Titanium GTAW Welding: Difficulties and Approaches
Welding titanium with the GTAW process presents distinct problems beyond those encountered with steel. The alloy's elevated reactivity, resulting oxide formation that can cause inclusions and reduced ductility, is a critical concern. Furthermore, titanium's reduced thermal conductivity makes managing the weld pool challenging. Approaches include meticulous preparation to remove scale before and during welding, employing inert gases like pure argon or He Tig welding aluminum to minimize scale formation, and utilizing precise settings – including decreased power and appropriate travel speeds. Correct procedure and experience are vital for high-quality Ti fabrication.
