Titanium GTAW Welding: Problems and Approaches
Welding Ti with the GTAW process presents unique problems beyond those encountered with steel. The metal's high reactivity, resulting oxide formation that can cause porosity and poor toughness, is a critical concern. Furthermore, the alloy's minimal thermal response makes controlling the weld pool difficult. Remedies involve meticulous cleaning to remove oxides before and during fabrication, employing inert gases like Ar or helium to inhibit oxidation, and utilizing controlled welding parameters – including lower power and appropriate travel speeds. Adequate procedure and experience stainless steel welding are essential for successful Ti joining.
