Titanium GTAW Joining: Problems and Solutions
Welding titanium with the gas tungsten arc process presents distinct difficulties beyond those encountered with ferrous metals. The metal's high reactivity, resulting oxide formation that can cause voids and poor ductility, is a critical concern. Furthermore, titanium's low thermal response makes controlling the weld pool problematic. Solutions involve meticulous preparation to remove oxides before and during welding, employing inert gases like argon or helium to minimize scale formation, and utilizing controlled conditions – including lower power and correct welding rates. Adequate procedure and expertise are essential for reliable titanium welding.
