Titanium TIG Fabrication: Challenges and Solutions
Welding titanium with the gas tungsten arc process presents distinct problems beyond those encountered with ferrous metals. The alloy's elevated reactivity, producing film formation that can cause inclusions and poor ductility, is a critical concern. Furthermore, titanium's reduced thermal heat transfer makes regulating the weld pool challenging. Approaches require meticulous degreasing to remove contaminants before and during welding, employing inert gases like pure argon or He to minimize scale formation, and utilizing precise welding parameters – including decreased voltage and appropriate travel speeds. Proper method and skill are crucial for reliable Ti alloy joining.
