Process Engineering   for   Friction Welding 

We engineer your made-to-measure friction welding process using the full potential of the latest techniques in numerical process simulation. We help you to

  • find the best available friction welding solution for your joining problem and

  • spare significant development time and costs.

By using the predictive process simulation  available by  our in-house  developed software  virtua RFW, we understand the mechanisms and effect chains of your friction welding process in a world-wide unprecedented way.  In a cooperative project we will guide  you through the four  basic stages of simulation-aided process development:


  1. Gathering information and specifications of your weld problem

  2. Work-out concept designs

  3. Simulative discussion and optimization of the favorite design

  4. Experimental validation of the optimized design

1. Gathering information and specifications

First of all we gather all relevant information together with you in order to allow  for an successful simulative process development. This particular involves:

  • Material, design and process chain of parent parts

  • Material parameters, e.g.  flow curves,  heat capacity and heat conductivity 

  • Experimental data of similar  welds

Specifications questionnaire :

  • Mechanical and thermal loads on the  joint?

  • Position and shape tolerances?

  • Are there any  sensitive  areas, e.g. hardened surfaces, which must not be annealed during welding?

  • Corrosion  requirements of the weld?

  • Packaging requirements?

  • Available machine equipment?

In cooperation with our partners we can offer you the entire  engineering scope of your friction welding application from scratch to working functional prototypes.  Get in contact with us for more information!

The Self-Centered Friction Welding process   (SCFW) is known from high-end applications within the transmission and power train  and sets new landmarks in position accuracy of friction welded components. The tapered joint angle allows for an self-alignment of the parent parts, which gives an unprecedented run-out precision of the welded compound. At the same time a radial joint interface with small space requirements is achieved, which is in particular favorable for shaft-hub joints of all kinds.


The process simulation in virtua RFW  allows for an simulation-aided development of the design and process parameters and thus facilitates a fast and efficient engineering  for new applications of this innovative process.
