Ti GTAW Fabrication: Challenges and Approaches
Welding Ti alloys with the gas tungsten arc process presents unique problems beyond those encountered with ferrous metals. The alloy's elevated reactivity, leading to oxide formation that can cause voids and brittle toughness, is a principal concern. Furthermore, titanium's reduced thermal response makes managing the heat-affected zone difficult. Approaches involve meticulous preparation to remove contaminants before and during welding, employing shielding gases like argon or a helium mix to minimize reaction, and utilizing controlled settings – including lower amperage and suitable feed rates. Proper method and skill are crucial for high-quality Ti welding.
