Titanium GTAW Joining: Problems and Solutions
Welding Ti with the gas tungsten arc process presents unique challenges beyond those encountered with steel. The metal's high reactivity, leading to film formation that can cause inclusions and poor formability, is a principal concern. Furthermore, titanium's low thermal conductivity makes controlling the heat-affected zone difficult. Remedies involve meticulous cleaning to remove contaminants before and during welding, employing shielding CNC machining parts gases like Ar or a helium mix to prevent scale formation, and utilizing careful welding parameters – including lower amperage and appropriate feed rates. Proper method and experience are crucial for reliable Ti alloy fabrication.
Austenitic Steel Tig Welding: Ensuring Strength
