Friction Stir Welding
- Quality in Depth
Cleaner, leaner, stronger
In contrast to conventional welding techniques, the FSW process requires no filler material, gas or other consumables - and consumes much less energy. Generating no harmful gases, no slag, no spatter and little sound, the process actively contributes to a better working environment, while simultaneously boosting productivity. Best of all, weld-strength quality is excellent.
FSW opens up whole new areas in welding technology. Rapid and high quality welds of aluminum 2xxx and 7xxx series alloys, as well as copper and magnesium - traditionally considered unweldable - are now possible.
