Ti Alloy TIG Welding: Problems and Approaches
Welding titanium with the gas tungsten arc process presents specific difficulties beyond those encountered with ferrous metals. The alloy's significant reactivity, resulting scale formation that can cause inclusions and poor toughness, is a major concern. Furthermore, Ti's minimal thermal response makes regulating the heat-affected zone difficult. Remedies involve meticulous cleaning to remove oxides before and during welding, employing shielding gases like Ar or helium to minimize reaction, and utilizing controlled settings – including decreased voltage and suitable welding rates. Adequate method and skill are essential for high-quality titanium fabrication.
