Friction stir welded radiators stay sealed


Tailored Welded Blanks (TWB) for Audi and Mercedes:

  • Our friction stir welded TWB in the Audi R8 was the first structural application of FSW in Europe, besides being the world’s first aluminium TWB

  • Friction stir welding is consistent, making it ideal for series production

  • For the Mercedes SL we manufacture the first threepart friction stir welded TWB in a mass-produced vehicle


Main floor of the Mercedes SL:

  • Extremely thinwalled profiles

  • Nevertheless high stability owing to special geometry


Radiators for electric cars:

  • Mass production

  • First automated manufacturing cell with FSW, machining, pressure testing

Energy and environment

Environmentally friendly aluminium welding

Energy and environment

  • Friction stir welding without rework despite seam in full view - no burrs
