Ti Alloy TIG Welding: Problems and Remedies
Welding Ti with the gas tungsten arc process presents distinct challenges beyond those encountered with ferrous metals. The material's significant reactivity, resulting scale formation that can cause inclusions and reduced formability, is a major concern. Furthermore, the alloy's minimal thermal response makes controlling the HAZ problematic. Remedies involve meticulous cleaning to remove oxides before and during joining, employing inert gases like Ar or a helium mix to inhibit oxidation, and utilizing careful welding parameters – including lower voltage and suitable feed rates. Proper technique and expertise are vital for high-quality titanium fabrication.
Stainless Steel Tig Welding: Ensuring Strength
To guarantee maximum joint strength when conducting Tig welding on austenitic steel , several important practices must be adhered to .
