Ti Alloy TIG Joining: Difficulties and Approaches
Welding titanium with the TIG process presents distinct difficulties beyond those encountered with carbon steel. The material's significant reactivity, producing film formation that can cause porosity and poor toughness, is a critical concern. Furthermore, Ti's low thermal conductivity makes managing the heat-affected zone problematic. Approaches include meticulous cleaning to remove scale before and during welding, employing shielding gases like pure argon or helium to minimize scale formation, and utilizing precise conditions – including lower power and suitable feed rates. Proper procedure and skill are essential for reliable Ti alloy joining.
Stainless Steel Tig Welding: Achieving Strength
