Ti GTAW Joining: Difficulties and Solutions
Welding Ti with the GTAW process presents unique problems beyond those encountered with ferrous metals. The alloy's high reactivity, producing oxide formation that can cause voids and poor ductility, is a major concern. Furthermore, titanium's reduced thermal heat transfer makes regulating the HAZ problematic. Solutions require meticulous degreasing to remove scale before and during welding, employing inert gases like argon or He to prevent reaction, and utilizing careful settings – including reduced amperage and correct welding rates. Adequate method and expertise are crucial for high-quality titanium fabrication.
