Compared to other methods, Friction Stir Welding offers so far unknown welding solutions. Welding absolutely tight aluminium-steel-joints is one of them. A combination of both metals offers countless advantages for industry sectors like the automobile industry or medical engineering.
The widely spaced melting points from 660°C and 1500°C lead to intermetallic phases when using traditional welding processes causing irregular solid and untight welding seams.
Friction Stir Welding allows to weld different metals solidly and absolutely gastight.These include:
- aluminium and steel
- aluminium and copper
- copper and steel
- alloys like brass and bronze
