Ti TIG Joining: Problems and Solutions
Welding Ti with the gas tungsten arc process presents specific difficulties beyond those encountered with ferrous metals. The material's elevated reactivity, leading to oxide formation that can cause voids and brittle ductility, is a major concern. Furthermore, Ti's minimal thermal response makes regulating the weld pool problematic. Remedies require meticulous preparation to remove contaminants before and during joining, employing shielding gases like Ar or a helium mix to inhibit scale formation, and utilizing careful conditions – including lower voltage and correct welding rates. Correct method and experience are essential for reliable titanium welding.
304 Stainless Tig Welding: Ensuring Strength
To obtain superior joint strength when executing Tig welding on stainless steel , several important practices must be observed.
