Titanium GTAW Fabrication: Problems and Approaches
Welding Ti with the TIG process presents specific problems beyond those encountered with ferrous metals. The metal's high reactivity, leading to oxide formation that can cause inclusions and poor toughness, is a major concern. Furthermore, Ti's low thermal heat transfer makes controlling the weld pool challenging. Approaches require meticulous preparation to remove oxides before and during welding, employing shielding gases like pure argon or helium to inhibit oxidation, and utilizing precise conditions – including lower power and appropriate welding rates. Proper procedure and skill are crucial for high-quality titanium welding.
