Ti GTAW Welding: Difficulties and Remedies
Welding titanium with the TIG process presents unique problems beyond those encountered with ferrous metals. The alloy's high reactivity, leading to oxide formation that can cause inclusions and brittle ductility, is a major concern. Furthermore, the alloy's minimal thermal response makes managing the heat-affected zone problematic. Approaches involve meticulous preparation to remove oxides before and during metal stamping joining, employing inert gases like argon or a helium mix to prevent scale formation, and utilizing controlled welding parameters – including decreased voltage and appropriate travel speeds. Adequate technique and skill are essential for successful Ti alloy welding.
