In contrast to conventional fusion welding and joining processes, friction stir welding offers completely new solutions, including joining tight aluminum-steel compounds. Combining these two metals as compounds is highly beneficial to several industries, for instance, the automotive sector and medical technology.
In conventional techniques, the enormous difference in melting points — 660 °C (1,220 °F / 933 °C) and up to 1,500 °C (2,732 °F / 1,773 °K) — leads to intermetallic phases during the welding process. As a result, the joint is often not consistently strong and tight. FSW makes it possible to join different metals in a strong and gas-tight manner.
We offer special solutions for (among others):
- Aluminum and steel
- Aluminum and copper
- Copper and steel
- Alloys, such as brass and bronze
