Can My Part Be Rotary Friction Welded?

MTI Welding Technologies — 02/05/2023

To start things off, let's talk about Rotary Friction Welding and how it works.

Rotary Friction Welding is a solid-state process in which one part is rotated at a high speed and is pressed against another part that is held stationary. The resulting friction heats the parts, causing them to forge together.

MTI is the only company that offers all three types of Rotary Friction Welding technologies - Inertia, Direct Drive and Hybrid.

Why Choose Rotary Friction Welding Over Other Processes?

In some cases, the parts we join with Rotary Friction Welding were, at one time, welded with a different joining process.

Rotary Friction Welding is a quicker, stronger and more environmentally friendly alternative to fusion welding processes such as electric arc or gas welding or high-energy processes like electron beam or laser welding.

Other key benefits of Rotary Friction Welding include:

The ability to join bimetallics or dissimilar metals
Faster weld cycles
Minimal joint preparation
Material and production efficiency

Parts Commonly Joined With Rotary Friction Welding

There are dozens of applications suitable for Rotary Friction Welding, but in this blog we will simply list some of the most common examples, split by industry.

MTI has a proud history of joining parts for Aerospace companies and suppliers. Aerospace parts are typically high-strength and lightweight and can greatly benefit from the repeatable weld quality and near-net shapes that Rotary Friction Welding helps provide.

Some of those Aerospace parts include:

Engine rotor components
Landing gear
Structural components
Rivets
Jet engine fan shafts
Rotor assemblies

Rotary Friction Welding is also a popular choice for the Automotive industry. There are dozens of automotive applications that take advantage of the technology's short cycle times, weld quality and machine-controlled process. Some of the most common examples are:

Airbag inflators
Drive shafts (steel and aluminum)
Bimetallic valves
Hollow gallery pistons
Turbo charger shafts

Additionally, the Rotary process is popular within the Construction and Agricultural industries. Some commonly joined Rotary parts for Construction and Agriculture include:

Track rollers
Hydraulic cylinder rods
Drill bits
Piston rods
Lift screws
Water pumps

Rotary Friction Welding is also used frequently in the Oil and Gas industry. Examples of parts in this industry joined with Rotary Friction Welding include:

Rock drilling pipe
Directional drilling pipe
Drill pipe
Geological core drills

Ok, What About My Part?

Now that you have an idea of what kind of parts can be joined with Rotary Friction Welding, your thoughts may now be shifting back to your particular part or application. Maybe it's similar to one of the parts listed above, or maybe it isn't - that's OK, too. A key way to determine whether Rotary Friction Welding is a good fit for your application is to consider its size.

There are three part characteristics that determine the machine size required to make a successful Rotary friction weld:

Area of the weld interface: Generally speaking, the larger the contact area between the two pieces, the greater amount of axial load that is required to make a weld.
Materials being welded: Different materials (and different material combinations) will yield different results in terms of size limitations. For example, Aluminum requires less axial force per unit of area compared to steel or other high-strength materials.
Weld joint geometry: The two most common weld joint geometries for Rotary Friction Welding are bar to bar or tube to tube, but a bar to plate and tube to plate are also common.

Once we define these three characteristics, we can start thinking about which type of Rotary Friction Welding machine is a good match for your job.

Finding Your Machine Match

MTI offers Rotary machines with as little as 500 pounds of axial force, all the way up to machines with 2,000 tons of axial force.

The smaller machines weld applications such as titanium rivets or small aluminum parts. But once you cross the 400-ton threshold, almost all of those machines are welding titanium or high-strength alloy aerospace components.

However, the majority of applications and machines we build fall between the 0 and 100-ton range.

To Contract or Not to Contract?

While MTI does build a wide range of Rotary Friction Welding machines, you do not necessarily need to buy one of our machines to take advantage of our solid-state process.

Our Contract Friction Welding division offers more than a dozen Rotary friction welders for you to use on your next project. The machines, which are available at both our UK and US Manufacturing Services locations, range in size from 500 pounds of forge force up to 400 tons.

Identifying your anticipated annual part volume is generally a good first step to help start the conversation of whether a dedicated machine would be a better fit for your needs.

Our machines are available for weld development, prototyping or production runs. Whether you need MTI to take your part from concept to completion, or you simply just need us to join your parts, we can create a custom solution for your project.

What's Next?

By now, you should have a solid idea of whether Rotary Friction Welding could be a suitable joining technology for your application. But, there's a good chance you still have some questions related to your specific part. Don't hesitate to reach out to Steve Marr, Head of Business Development in Europe, at steve.marr@mtiwelding.co.uk

To help prepare for our first conversation, it's helpful to communicate or provide some of the things we have talked about in this blog, including a part sketch, a description of your part's purpose, whether you are interested in buying a friction welder, your anticipated timeline and a projected budget.

Linear Friction Welding: A Solution for Titanium Forgings

MTI Welding Technologies — 28/08/2023

In the world of Aerospace and advanced engineering, titanium forgings have long been hailed as critical, unique materials for their lightweight yet high strength properties. However, a recent and developing disruption to the existing supply chain may threaten the availability of these critical components.

Amidst this challenging scenario, a promising solution emerges – Linear friction welding, a cutting-edge technique that has the potential to mitigate the crisis and revolutionize the manufacturing of titanium forgings.

The Challenge

As a critical and highly demanded material, supply chain issues cause disruptions for the companies that depend on it. Given the sometimes complex geometry and critical nature of the components manufactured from the forgings, the tooling and machines required to provide an alternative solution to component supply are not easily replaced. That brings us to the current challenge. Russia is a top supplier in the titanium market, accounting for nearly 20% of the global supply and 45% of titanium Aerospace components.

With international sanctions being imposed against Russia (and predicted to increase), it's essential to consider alternative ways of manufacturing titanium forgings that are cost effective and environmentally conscious.

Titanium Forgings

So, why are titanium forgings so unique?

Titanium forgings refers to Titanium that has undergone a forging process where the metal is hot forged into the required geometry according to the desired application. By undergoing a forging process, the titanium gets enhanced strength, improved material integrity, and a longer useful life with minimal maintenance needed because the grain direction is manipulated in accordance to the load path within the component during its service life. Besides enhanced strength, titanium is also forged because the price per pound of raw titanium is high, and forgings are designed to minimize the amount of expensive material that needs to be removed.

And for the Aerospace industry where many airframe components are manufactured from titanium forgings since the end product typically weighs between 150-220 tons, titanium is a critical component when trying to trim weight without compromising safety of mission critical components.

Forging A Solution: Linear Friction Welding

Like all friction welding processes, Linear friction welding is a forging technique that generates heat from relative motion and axial force to create a solid-state weld. Linear friction welding applies an oscillatory motion while the components are in contact to generate heat which allows any geometry to be joined. Once the oscillatory motion between the components has plasticized the weld interface, the bond is consolidated by rapidly stopping oscillation and forging the components together creating a solid-state bond.

So, how can Linear friction welding be used to manufacture titanium forgings?

One of the most unique benefits that Linear friction welding offers is near-net shape joining, also known as close contour. Near-net shape manufacturing is the process of joining several smaller parts to form a larger part. This enables 3 dimensional tailored blanks with virtually any geometry to be produced on a single machine. Using the appropriate tooling, near-net shapes can be built from individual stock sections or smaller forgings, allowing the finalized welded part to be very close to the end product's geometry. You may recall near-net shape manufacturing for blisks in the Aerospace industry.

But, did you know that near-net shape manufacturing is especially advantageous for titanium and titanium alloys? That's because titanium is an expensive material, and close contouring provides production flexibility and reduces machining time and production costs while wasting less material. In other words, Linear friction welding can reduce Aerospace companies' buy-to-fly ratio by up to 90% when compared to billet machining and around 50% when compared to forging with near-net shape manufacturing of titanium. In addition to the material cost and machining time savings, near-net shapes manufactured from prismatic stock material provide consistent clamping locations and eliminate the need for a separate pre-machining step for clamping faces during production.

Another unique advantage of Linear friction welding is the ability to manipulate the grain structure of the material, in this case titanium. Linear friction welding has the ability to align the grain structure of the subsections within the tailored blank in accordance with the load path of the part. This is especially beneficial as favorably manipulating the grain structure increases the performance of the titanium in comparison to billet machining, making the Linear friction welded component performance similar to that of forged structures all while using less energy, less material, and less machining time than traditional forging methods.

The Process

MTI has developed a streamlined production process using titanium subsections to produce full-scale, near-net shapes. Take a look:

1. Nesting of titanium blanks from plate - The process starts with a titanium plate. The components needed to construct the near-net shapes will be orientated according to the rolling direction of the material and the most efficient extraction layout. The components will then undergo water jet cutting.
2. Weld subsections together - This is where Linear friction welding comes in. In most cases, with the correct tooling, the components can be welded directly from the water jet cutting machine. Depending on the geometry of the manufactured part, some pre-weld preparation may be required. Linear friction welding can then be performed in sequence to produce near-net shapes from the titanium. During construction, complex geometries or critical safety components might need to undergo non-destructive testing. However, this can be done using automation systems away from the friction welding machine, if necessary.
3. Heat treatment - MTI has worked closely with multiple manufacturers to define an appropriate heat treatment and stress relieving process that compliments the Linear friction welding process. Heat treating helps to avoid the formation of cracks in the material and can further improve fatigue resistance.
4. Final machining - Once Linear friction welding is completed, final machining must be done to the near-net shape parts to complete the component's final form.

This illustration evaluates the differences in material required to produce a pre-machined near-net shape when using LFW (Linear Friction Welding), forgings, and a prismatic billet. In this generic comparison, an LFW blank and a forging would yield a 67% reduction in material in comparison to a forging, and an 80% reduction in comparison to a prismatic billet. While these figures are hypothetical, they are indicative of actual values that have been defined through detailed product assessments.

And, getting started with friction welding is easier than you may think! At MTI, we have teams dedicated to helping you from the creation of your part drawings to the manufacturing of production-ready components, all included in our comprehensive Weld Development program.

MTI and Siemens Join Forces to Lead the Way in Welding Technology for The Axle Market.

MTI Welding Technologies — 19/12/2017

Global joining solutions provider MTI collaborated with technology company HMK, the Siemens motion partner, to pioneer the development of a double axle friction welding machine worth in excess of £2 million for one of the worlds leading trailer manufacturers.

The 16m friction welding machine, which was delivered in February of 2017, welds a complete axle in just one cycle. The machine sets a new standard for the axle industry, reducing cycle times by up to 10 percent and potentially reducing the requirement of a third shift.

MTI invested 2000 hours to design this machine, but the cost and efficiency benefits it will deliver to customers are unbeatable, said MTI Managing Director Richard Jones.

A fully automated machine, the double axle friction welder eliminates slow and manual part load and unload operations. Specifically designed for the axle market, fully finished axles for multiple applications are delivered with precision part accuracy and statistical data monitoring for the quality process.

Its already well-exceeded expectations of the customer and with these results as evidence, we look forward to introducing the double axle friction welder to new clients and markets, said Jones.

Surpassing rigid industry specifications, the machine delivers workpiece orientation to less than ±1° and achieves TIR up to 0.25 mm. The double axle machine also features a CpK rating of 1.67, a critical performance measurement utilised by the industry which demands a CpK of 1.33 or above to satisfy most automotive customers.

The impressive friction welder also features automatically-positioning clamps and offers near-unlimited recipes through its PC interface, allowing different axle production runs to be scheduled on one machine. This eliminates the need to juggle schedules across multiple, single-weld machines.

Several other complex features have been designed into the machine to allow the customer to enhance its patented technology developments for future axle designs.

As MTIs most advanced double axle friction welder, the machine is the first of its kind to utilise Siemens SIMOTION high-end motion control system along with the latest motor and drive technology from Siemens SINAMICS range which is Industry 4.0 ready.

We are very proud to have partnered with HMK to develop such a revolutionary welding machine, said Jones. With its market-leading Siemens operating system and MTIs patented welding technology, you would be hard-pressed to find another product that offers such flexibility and process control.

MTI's friction-welding kernel has been architected to maximise its use of the SIMOTION platform. By fully utilising the available powerful task architecture and execution system available, the system can adjust the priority of tasks within the processor according to when their execution is at its most critical for the friction-welding process. As a result, the friction-welding process can be controlled down to a sub-millisecond level.

Processing of the servo-drive position loops is also passed down to the drive using Dynamic Servo Control (DSC) to reduce task-load on the processor and improve performance. The system offers unrivalled control over process parameters including spindle position in-cycle for even tighter finished part tolerances than previously thought possible.

In addition to the aforementioned features, the machine takes full advantage of the Safety-Integrated functions offered with the SINAMICS drive-system to allow safe operation of the machine via teach-pendant for set-up.

Equipped with market leading machine performance statistics, MTI is now focusing on introducing the double axle friction welder to new customers in the axle and trailer industry whilst simultaneously expanding into the truck and lorry transmission market.

Friction Welding for Turbochargers

MTI Welding Technologies — 20/09/2023

The Automotive industry is no stranger to friction welding. Within an Automotive vehicle's internal combustion engine lies around 2,400 parts that must work together to get us from point A to point B, and friction welding is used to join many of those parts! One of those parts is the Turbocharger.

Turbochargers are a vital component for automotive vehicles, providing a significant boost in power and performance and enables engines to be smaller and more fuel-efficient. As a key component, its important turbochargers are manufactured with quality, durability, and repeatability in mind.

Why Friction Welding?

While there are a few joining techniques that can be used to join turbochargers, the top choice is friction welding for its exceptional joint strength and reliability.

Take a more traditional method such as MIG or TIG welding, which are also used to join turbochargers. These are fusion processes that will introduce higher heat and possible contamination to the material being joined, which poses a risk to the material’s mechanical properties. Friction welding is a solid-state joining technique where melting never occurs, which means the materials keep all if not most of their mechanical properties.

So, what are the benefits of Friction Welding for Turbochargers?

1. Joining bimetallics / dissimilar materials – Friction welding has the broadest capabilities for joining dissimilar materials with the same high-strength bond you’d come to expect. Typically, turbochargers are made from two different metals, take Steel and Inconel as an example. Steel is an ideal choice for the turbocharger shafts as it needs to be Hardenable and wear-resistant. Inconel can be used for the wheel for its heat-resistance and high-strength. This allows you to save on material costs by using Steel where Inconel (or another expensive material) isn’t required.
2. Superior joint strength & part repeatability – Friction welding creates a solid-state bond of forged-quality for the optimal joint strength. And, because the friction welding process is machine-controlled with pre-determined parameters, each part is made consistently without operator error.
3. Improved fatigue resistance – Friction welding produces welds with excellent fatigue resistance which is particularly advantageous for turbochargers as they experience high cyclic loads and vibrations, ensuring durability and reliability.
4. Pre and post-weld processing – Most turbochargers require post-weld heat treating as they are made from Hardenable materials which requires higher energy input to make a higher strength weld joint. The friction welding process allows for careful variations of the energy input and cooling rates optimising the integrity of the final weld joint.

Why MTI?

MTI has been a trusted producer of automotive components for nearly 100 years - our extensive experience, dedication to quality, and industry know-how make us the right solution for you. Additionally, MTI has the widest range of Rotary friction welding technologies including Direct Drive and Inertia, both of which are excellent choices for joining turbochargers.

A Step-by-Step Guide to MTI's Weld Development Process

MTI Welding Technologies — 16/05/2023

Practice makes perfect: it’s an old saying, but one that continues to ring true in just about every aspect of life – especially when it comes to manufacturing.

At MTI, we wouldn’t necessarily label our weld development process as practice, but the concept follows a similar flow – plan, detect, adjust.

It’s true, our experienced team of engineers would certainly be able to offer predictions based on historical experience about what might happen if certain materials and geometries were to be joined through friction welding. After all, our team has a combined 300 years of friction welding experience. However, we couldn’t be certain about the results until we studied each angle of the project and considered each of the customer’s requests.

This thorough testing process is known as a weld development.

Why You Need a Weld Development

While MTI has decades of experience successfully joining countless materials for all industries, no two jobs are the same. For example, the performance needs of a drive shaft are different from a shock absorber body, even if the materials are identical.

Each material combination, weld geometry, incoming part condition and tooling concept must be proven with experimental data in order to avoid a lengthy post-weld testing process. This saves not just time, but also money because we are cutting down on material wastage by identifying solutions earlier in the friction welding process.

The main purpose of a weld development is to optimise the results that ensure the production parts are fit for purpose. This promotes extended part life, reduces scrap, and fosters a strong weld and design.

A special emphasis is placed on our aerospace customers who may be utilising powdered materials in their applications. In addition to the different complexities of those materials, we realise all aerospace applications require a foundation of weld data and destructive testing to prove that each weld is fit for purpose based upon machine data collected during welding.

Let's learn about the different forms of friction welding and explore which one may be best for your application.

What is Friction Welding?

Before we dive into the weld development process, let’s talk about friction welding and how it’s different from other welding methods.

Friction welding is a solid-state process and comes in several different forms: Rotary friction welding, Linear friction welding, Friction Stir welding, plug welding, and our newest technology, Low Force friction welding.

Friction welding creates a 100-percent bond of the contact area and creates joints of forged quality. The weld properties are superior to welds created with fusion processes, such as MIG or TIG welding, because a friction weld does not result in melting. The absence of melting helps create a higher strength bond and greatly increases the design flexibility of each part.

Additionally, friction welding requires minimal joint preparation, is a repeatable process, produces faster cycle times and can join dissimilar metals.

In fact, one of the best reasons to take advantage of a weld development is for joining bimetallics, since the material properties can vary greatly from one metal to another.

Now that you’re familiar with how friction welding works, let’s talk about what to expect when you contact MTI to begin a weld development program.

Beginning the Weld Development Process

When you sit down with MTI for the first time to discuss your project, you will need to provide us with a few pieces of information, including:

The materials to be joined
Specifications of the materials to be joined to your supplier's expectations
The geometries to be joined
The area at the weld interface (diameter and wall thickness for tubular weld geometries)
The purpose the finished part will serve
Annual part volume expectations

One of the best ways to begin this conversation is to offer a part print or sketch of the application you want to create or improve. Having a sketch is much more beneficial and will provide more detail than if you described your part over the phone or an email.

Identifying a Timeline

Our team should be able to give you a rough estimate of the time required for a weld development while the conversation is in its earliest stages.

How much time it takes to elevate each part from concept to completion relies on many factors, including:

Whether MTI has friction welded your application before
Whether MTI has friction welded your materials before
The complexity of your parameters
The number of industry quality certifications your application must meet
Whether you want a machine built for your application

MTI’s weld development program is comprised of three phases. However, this multi-phase approach is generally only needed when we are doing something new. It may not be required for Rotary friction welding. We may enter a Boundary Condition Phase where we determine how to use weld development data to ensure weld quality for machine data during production.

The traditional three phases are classified as:

Phase 1 – Proof of Concept: In this phase, our team determines, through a variety of different tests, whether it’s feasible to join your materials and geometries.

Phase 2 – Small-Scale Development: In Phase 2, we develop small-scale portions of your part to test their strength and durability.

Phase 3 – Large-Scale Development: In this phase, we develop full-scale parts to test their viability on our friction welders. This is the final step before producing production parts.

Now, let’s explore each phase of the weld development to learn more about each step of the process.

Phase 1 - Proof of Concept

At MTI, we define a successful weld as a joint that meets the performance requirements that are fit for the purpose of the welded assembly we’re creating.

The fit-for-purpose performance requirements may include:

Heat Affected Zone (HAZ) width
The hardness of the HAZ
Tensile strength at the weld line
High and low cycle fatigue
Elongation
Yield strength
Residual stress
Microstructure

These qualities can be determined through metallurgical testing. Both MTI’s UK and US locations have in-house metallurgical labs equipped with various equipment to complete these tests.

Without identifying the relevant qualities listed above, the designer of a production part assembly cannot design the joint. That’s why it’s critical that MTI identifies these details before the design process begins.

It’s important to note that the process forces in friction welding are significantly different than other processes, so the part must be designed to withstand those forces – that’s why there are so many layers to our initial steps.

Plus, the resulting metallurgical and physical properties are different than any other joining process, so those must also be considered for the part design. Redesigning the part for optimised properties will change the process forces and redesigning the part for process forces can change the metallurgical and physical properties of the resulting weld.

Phase 2 - Small-Scale Development

Once we have gathered all the required knowledge of the materials and the assembly, we can begin working toward developing small-scale parts for testing. This step also involves fine-tuning the tooling required to fit your part on an MTI friction welder.

If we use the same material and choose the correct parameters for evaluation, then these parameters are not specific to a geometry of a weld – they are scalable to larger welds. This is especially important later when we are ready to move on to larger-scale development parts.

Friction welding is a repeatable process because there are only two variables the machine must control – energy and forge force. These are tweaked to produce the intended result. The combination of forge force and energy leads to upset, which is a loss of length in the part. That upset often translates into weld flash, which is the extrusion of plasticised material at the weld line. Flash may form as a smooth curl or jagged ribbon in traditional friction welding. With Low Force friction welding, there may be no flash at all.

With some additional evaluations surrounding the upset, we can ensure that slight non-machine variations to the process do not change the material properties of the application.

This process will ensure each weld produced by the machine is a good weld. This will also produce the data that the designer needs to create the part while the manufacturing team focuses on the design of the process.

In this stage of weld development, upset can be used as a quality assurance tool if you have the data to show that the pressure and energy produced a good-quality weld, as demonstrated by the mechanical and physical testing done ahead of time.

Once we weld sample parts, we will conduct a post-weld inspection. This looks for flaws that may not show up on machine data, such as incoming flaws in the forging or a lack of proper clean-up in post-weld machining.

To Contract or Not to Contract?

Also at this point in the process, we should be able to identify whether you want MTI to handle your project with our Contract Friction Welding services or if you are interested in joining your new parts on your own MTI-built friction welder.

If you choose to purchase a dedicated friction welder for your project, we will handle the weld development on our in-house machines while yours is being built.

Alternatively, you have the option of purchasing a lab machine, which is designed to facilitate the foundation of the data needed for your project.

In that case, we would begin the development on our machines until your lab machine was ready.

Phase 3 - Large-Scale Development

Once you and our team are satisfied with the data and results produced in the Proof of Concept and Small-Scale Development phases, we can move on to full-scale development. These parts will mirror your final product and will serve as the last step before achieving production-ready parts.

While the small-scale development may focus on one portion of the part, such as the weld, in this phase, we observe how the entire part reacts to the process in its entirety to ensure the quality is maintained.

Ready to Begin?

By now, you should have a solid understanding of MTI’s weld development process and what to expect in each phase. However, it’s important to note that there is a lot more depth to our process than is represented in this document. To explore your application further, we would sign a mutual NDA so we can learn more about your application and you can gain a better understanding of our process.

MTI Friction Welding for Electric Vehicles (EVs)

MTI Welding Technologies — 27/06/2023

As electric vehicles continue to claim larger percents of yearly automotive sales across Europe and the world, new opportunities are constantly presenting themselves for companies that support the auto industry.

Friction welding is the most effective bimetallic joining technology available. With friction welding, the welds are of forged quality and the materials are plasticised rather than melted, creating higher strength welds than fusion processes. Plus, a properly developed friction weld will not develop galvanic corrosion, also known as bimetallic corrosion, around the joint.

Here are three common friction welding applications for EVs made from joining copper to aluminium:

1. Rotary friction welded eletrical connectors

MTI uses Rotary friction welding to join aluminium alloys to copper alloys for electrical connectors. By doing so, we get the benefit of copper’s heat transfer properties combined with the cost saving benefits of using aluminium.

2. Rotary friction welded battery cables

MTI also uses Rotary friction welding to join copper to aluminium for battery cables. In this case, copper and aluminium are both ideal for different reasons. Copper provides high electrical conductivity with little resistance while aluminium is a much lighter metal. By substituting heavier metals for aluminium when applicable, we’re able to reduce the weight of the final vehicle, which is referred to as lightweighting. That’s why combining aluminium with other materials has become a critical aspect of automotive production.

3. Linear friction welded heat exchanger plates

Using Linear friction welding, MTI joins copper to aluminium to form heat exchanger plates for vehicles. While copper transfers heat faster than almost any other metal, copper doesn't mount to other surfaces very well or very rigidly. So, copper is welded to aluminium, allowing the aluminium to be used as the mounting surface.

Have you made the switch to electric vehicles?
