Ti Alloy TIG Welding: Challenges and Remedies
Welding Ti with the GTAW process presents unique challenges beyond those encountered with steel. The material's elevated reactivity, resulting film formation that can cause inclusions and poor toughness, is a major concern. Furthermore, the alloy's low thermal heat transfer makes managing the weld pool problematic. Approaches require meticulous preparation to remove scale before and during joining, employing inert gases like pure argon or He to inhibit scale formation, and utilizing controlled conditions – including lower voltage and correct travel speeds. Adequate method and experience are vital for high-quality titanium welding.
