Titanium TIG Fabrication: Difficulties and Approaches
Welding Ti with the TIG process presents unique problems beyond those encountered with carbon steel. The alloy's elevated reactivity, leading to scale formation that can cause inclusions and reduced formability, is a major concern. Furthermore, Ti's low thermal conductivity makes regulating the HAZ problematic. Solutions involve meticulous preparation to remove scale before and during fabrication, employing shielding gases like pure argon or a helium mix to metal stamping prevent reaction, and utilizing careful settings – including decreased voltage and appropriate travel speeds. Correct technique and experience are crucial for successful titanium fabrication.
Austenitic Steel Tig Welding: Ensuring Strength
