Ti Gas Tungsten Arc Joining: Challenges and Approaches
Welding Ti with the TIG process presents specific difficulties beyond those encountered with carbon steel. The alloy's high reactivity, leading to scale formation that can cause voids and brittle ductility, is a critical concern. Furthermore, the alloy's low thermal heat transfer makes controlling the weld pool difficult. Approaches require meticulous preparation to remove oxides before and during joining, employing shielding gases like Ar or He to minimize oxidation, and utilizing precise welding parameters – including reduced voltage and correct welding rates. Correct procedure and skill are vital for high-quality Ti alloy fabrication.
Stainless Steel Tig Welding: Achieving Strength
To guarantee optimal joint strength when performing Tig welding on 304 stainless, several essential practices must be adhered to .
