Ti TIG Welding: Challenges and Approaches
Welding Ti with the TIG process presents unique problems beyond those encountered with ferrous metals. The metal's elevated mig welding reactivity, producing film formation that can cause porosity and poor ductility, is a principal concern. Furthermore, the alloy's reduced thermal response makes regulating the heat-affected zone problematic. Remedies require meticulous degreasing to remove contaminants before and during welding, employing shielding gases like Ar or He to prevent oxidation, and utilizing precise conditions – including lower voltage and appropriate travel speeds. Proper method and expertise are vital for reliable titanium welding.
