Ti Alloy Gas Tungsten Arc Joining: Problems and Remedies
Welding Ti alloys with the GTAW process presents unique difficulties beyond those encountered with steel. The metal's elevated reactivity, leading to oxide formation that can cause inclusions and poor formability, is a major concern. Furthermore, Ti's low thermal heat transfer makes controlling the heat-affected zone challenging. Approaches include meticulous preparation to remove contaminants before and during welding, employing shielding gases like Ar or a helium mix to inhibit reaction, and utilizing precise welding parameters – including lower power and correct travel speeds. Correct procedure and expertise are crucial for successful Ti alloy joining.
Stainless Steel Tig Welding: Ensuring Strength
To guarantee optimal joint strength when executing Tig welding on 304 stainless, several essential practices must be observed.
