Ti GTAW Welding: Problems and Approaches
Welding titanium with the gas tungsten arc process presents specific problems beyond those encountered with carbon steel. The alloy's high reactivity, leading to scale formation that can cause inclusions and poor ductility, is a principal concern. Furthermore, titanium's minimal thermal response makes managing the HAZ difficult. Approaches require meticulous degreasing to remove oxides before and during welding, employing inert gases like pure argon or He to prevent scale formation, and utilizing precise settings – including reduced power and appropriate travel speeds. Adequate technique and expertise are essential for reliable titanium fabrication.
