Titanium GTAW Joining: Problems and Remedies
Welding Ti alloys with the gas tungsten arc process presents distinct problems beyond those encountered with carbon steel. The metal's high reactivity, leading to oxide formation that can cause porosity and poor toughness, is a major concern. Furthermore, titanium's low thermal conductivity makes regulating the weld pool challenging. Solutions require meticulous preparation to remove scale before and during welding, employing shielding gases like pure argon or He to prevent reaction, and utilizing controlled welding parameters – including lower voltage and appropriate travel speeds. Proper procedure and skill are vital for high-quality Ti welding.
Stainless Steel Tig Welding: Ensuring Strength
To obtain superior joint strength when performing Tig welding on 304 stainless, several critical practices must be followed .
