Titanium TIG Fabrication: Challenges and Approaches
Welding titanium with the gas tungsten arc process presents distinct problems beyond those encountered with steel. The metal's high reactivity, resulting film formation that can cause inclusions and poor ductility, is a major concern. Furthermore, the alloy's reduced thermal response makes regulating the weld pool difficult. Approaches require meticulous degreasing to remove scale before and during welding, employing protective atmospheres like pure argon or He to minimize oxidation, and utilizing careful welding parameters – including lower voltage and suitable welding rates. Proper method and expertise are essential for reliable Ti alloy joining.
