Ti Alloy TIG Fabrication: Problems and Remedies
Welding Ti with the GTAW process presents specific problems beyond those encountered with steel. The alloy's significant reactivity, resulting oxide formation that can cause porosity and reduced ductility, is a critical concern. Furthermore, titanium's reduced thermal response makes controlling the weld pool problematic. Approaches involve meticulous degreasing to remove oxides before and mig welding during joining, employing inert gases like Ar or He to inhibit oxidation, and utilizing controlled conditions – including reduced voltage and correct feed rates. Adequate procedure and experience are crucial for reliable Ti alloy fabrication.
