Ti GTAW Welding: Challenges and Remedies
Welding Ti alloys with the GTAW process presents distinct challenges beyond those encountered with steel. The alloy's elevated reactivity, producing scale formation that can cause voids and brittle formability, is a major concern. Furthermore, Ti's minimal thermal conductivity makes controlling the heat-affected zone problematic. Approaches include meticulous degreasing to remove oxides before and during joining, employing inert gases like pure argon or helium to inhibit metal stamping oxidation, and utilizing controlled conditions – including lower power and appropriate feed rates. Proper procedure and expertise are essential for reliable Ti joining.
Stainless Steel Tig Welding: Maximizing Strength
To obtain optimal joint strength when executing Tig welding on stainless steel , several essential practices must be observed.
