Ti Alloy TIG Fabrication: Challenges and Solutions
Welding titanium with the TIG process presents distinct difficulties beyond those encountered with ferrous metals. The alloy's high reactivity, resulting oxide formation that can cause porosity and poor ductility, is a major concern. Furthermore, titanium's low thermal response makes regulating the HAZ problematic. Solutions include meticulous cleaning to remove oxides before and during welding, employing shielding gases like argon or He to minimize scale formation, and utilizing controlled conditions – including reduced voltage and appropriate travel speeds. Proper procedure and experience are essential for high-quality titanium fabrication.
Stainless Steel Tig Welding: Achieving Strength
To guarantee superior joint strength when executing Tig welding on stainless steel , several important practices must be observed.
