Ti Alloy TIG Fabrication: Problems and Solutions
Welding Ti with the GTAW process presents specific problems beyond those encountered with ferrous metals. The metal's significant reactivity, producing oxide formation that can cause porosity and poor toughness, is a major concern. Furthermore, titanium's minimal thermal response makes regulating the heat-affected zone challenging. Remedies include meticulous cleaning to remove contaminants before precision metal products and during welding, employing inert gases like argon or He to inhibit scale formation, and utilizing careful welding parameters – including lower amperage and appropriate feed rates. Proper procedure and skill are vital for reliable Ti joining.
