Ti GTAW Fabrication: Challenges and Remedies
Welding titanium with the GTAW process presents unique challenges beyond those encountered with steel. The alloy's significant reactivity, producing film formation that can cause inclusions and brittle ductility, is a major concern. Furthermore, Ti's reduced thermal response makes controlling the weld pool difficult. Approaches include meticulous degreasing to remove oxides before and during fabrication, employing inert gases like pure argon or a helium mix to minimize oxidation, and utilizing careful settings – including reduced voltage and suitable travel speeds. Correct procedure and expertise are essential for reliable Ti fabrication.
