Titanium TIG Fabrication: Challenges and Approaches
Welding Ti alloys with the GTAW process presents distinct difficulties beyond those encountered with ferrous metals. The alloy's significant reactivity, resulting film formation that can cause inclusions and brittle toughness, is a major concern. Furthermore, titanium's minimal thermal conductivity makes controlling the HAZ problematic. Solutions include meticulous degreasing to remove scale before and during joining, employing shielding gases like argon or a helium mix to minimize reaction, and utilizing careful welding parameters – including lower power and appropriate welding rates. Adequate technique and skill are crucial for reliable titanium joining.
