Ti GTAW Fabrication: Difficulties and Remedies

Welding Ti with the gas tungsten arc process presents specific difficulties beyond those encountered with ferrous metals. The alloy's significant reactivity, producing scale formation that can cause voids and poor ductility, is a critical concern. Furthermore, titanium's reduced thermal heat transfer makes managing the heat-affected zone problematic. Approaches involve meticulous degreasing to remove scale before and during joining, employing shielding gases like pure argon or helium to prevent scale formation, and utilizing precise settings – including reduced amperage and correct feed rates. Correct procedure and expertise are essential for successful Ti welding.

Austenitic Steel Tig Welding: Achieving Strength
