Ti Alloy Gas Tungsten Arc Fabrication: Problems and Remedies
Welding Ti alloys with the GTAW process presents specific problems beyond those encountered with carbon steel. The material's significant reactivity, producing oxide formation that can cause voids and brittle formability, is a critical concern. Furthermore, Ti's low thermal conductivity makes controlling the heat-affected zone problematic. Approaches require meticulous cleaning to remove scale before and during fabrication, employing shielding gases like argon or a helium mix to prevent scale formation, and utilizing careful welding parameters – including lower amperage and correct travel speeds. Adequate technique and experience are crucial for high-quality titanium welding.
Austenitic Steel Tig Welding: Maximizing Strength
To guarantee superior joint strength when executing Tig welding on austenitic steel , several important practices must be observed.
