Titanium TIG Joining: Problems and Approaches
Welding Ti alloys with the gas tungsten arc process presents unique problems beyond those encountered with carbon steel. The alloy's high reactivity, resulting film formation that can cause porosity and reduced toughness, is a principal concern. Furthermore, titanium's minimal thermal response makes regulating the weld pool problematic. Solutions involve meticulous degreasing to remove oxides before and during fabrication, employing shielding gases like Ar or helium to minimize oxidation, and utilizing careful conditions – including lower power and suitable travel speeds. Proper technique and experience are crucial for high-quality titanium fabrication.
