Investigation of new welding technology for aluminium

The Belgian welding Institute and the Aluminum Center will start a research project about a new spot weld technique; friction spot welding. The connection is created by using friction. This welding technology is particularly suitable for welding aluminium, and provides a solution to the difficulties that resistance spot welding is facing when joining aluminium, such as the electrode wear and tool life.


  • ideal for welding aluminium,
  • offers a solution to the problems of the resistance spot welding of aluminium alloys,
  • welding of advanced higher-strength aluminium alloys is possible, which are not weldable with conventional welding techniques,
  • welding of dissimilar materials, such as aluminium-steel, coated aluminium alloys, or materials with unequal thicknesses,
  • short welding time,
  • ecological process: no filler materials or protective gases are used and there are no welding fumes, IR-, UV- or electromagnetic radiation.

Aim of the project

To demonstrate the possibilities of this process and to investigate the implementation, a practical research project will be conducted. The goal is to explore the possibilities of this process in terms of weldability of materials and applicability in industry.

In addition, industrial case studies will be developed to show the potential of the process. These new possibilities, more specific the use of lightweight materials and the possibility to combine them with conventional steels, will allow you to manufacture products with a smaller weight, a better performance, or an increased integration of functionalities, and therefore a higher added value.

Interested in participating ?

If you are interested to follow up this project, please fill in the letter of intent, and send it to the Belgian Welding Institute (mail, email or fax). If you don’t have a specific application in mind yet, but if you wish to follow up the further evolution of this technology, please let us also know as well, so we can send you updates on the project. Only registered companies are entitled to receive the reports and results of the investigation (defined contractually by IWT). The project can only be started if there is sufficient interest from the industry.
