Ti Alloy GTAW Fabrication: Problems and Approaches
Welding titanium with the gas tungsten arc process presents distinct challenges beyond those encountered with carbon steel. The alloy's high reactivity, producing film formation that can cause porosity and reduced formability, is a major concern. Furthermore, titanium's reduced thermal heat transfer makes controlling the weld pool challenging. Solutions require meticulous degreasing to remove oxides before and during welding, employing shielding gases like pure argon or helium to minimize scale formation, and utilizing precise welding parameters – including lower amperage and appropriate travel speeds. Adequate procedure and experience are crucial for high-quality Ti alloy welding.
Austenitic Steel Tig Welding: Ensuring Strength
