What is friction welding?
Why use friction welding?
The benefits of friction welding are numerous. Amongst other things, friction welding allows components to retain the strength of its parent material. In situations where one part of the component demands very specific capabilities (i.e. stainless, corrosion resistance) and another does not, friction welding eliminates the need for building components out a solid piece of expensive material. These all add up to savings through the entire production process, from using only the right material for the right job, and saving money on CNC machining.
Knowledge is key
We have built up our expert knowledge about friction welding and we have refined our manufacturing process over the years. Please have a look at our knowledge library for brief information and tips & tricks.

Friction welding utilized
The history of rotary friction welding goes back several decades. The automotive and aerospace industries have both utilized friction welding for years. Relying on the strength of the welds and possiblities afforded by using expensive materials only where needed.
Thomson has been Aviatec’s main supplier of friction welding machines. As of 2020 Aviatec has three friction welding machines at their disposal. Combined with the modern CNC lathes Aviatec is able to assist with the production requirements are customers have.
Literature Review of Friction Welding Research – march 9, 2020
“This literature review is the startup of a project regarding an analysis of rotary friction welds. The statement to be investigated is that cylindrical elements joined by means of friction welding are stronger/harder than similar elements joined by classical welding methods.This statement is based on experience from an automotive parts supplier and has withstood the test of time.Therefore, this literature review will cover literature on friction welding in general, and more specifically on rotary friction welding. It will also give an overview of experimental results in literature, regarding a varietyof different material combinations. Due to the task of analyzing the welding theoretically, we will also review the use of mathematical models for prediction of temperatures and hardening processes in the weld components.”
