Titanium TIG Fabrication: Problems and Remedies
Welding Ti alloys with the gas tungsten arc process presents unique difficulties beyond those encountered with ferrous metals. The alloy's high reactivity, leading to oxide formation that can cause inclusions and poor ductility, is a critical concern. Furthermore, Ti's low thermal conductivity makes regulating the heat-affected zone challenging. Remedies involve meticulous degreasing to remove scale before and during welding, employing inert gases like pure argon or He to prevent reaction, and utilizing careful settings – including decreased amperage and correct travel speeds. Correct procedure and experience are essential for reliable titanium welding.
