Ti Gas Tungsten Arc Joining: Challenges and Approaches
Welding Ti with the gas tungsten arc process presents unique challenges beyond those encountered with carbon steel. The metal's elevated reactivity, leading to oxide formation that can cause inclusions and brittle toughness, is a principal concern. Furthermore, titanium's minimal thermal conductivity makes managing the weld pool problematic. Remedies include meticulous cleaning to remove scale before and during welding, employing shielding gases like pure argon or helium to minimize oxidation, and utilizing controlled settings – including decreased power and appropriate feed rates. Proper procedure and skill are essential for successful titanium welding.
Austenitic Steel Tig Welding: Ensuring Strength
To obtain superior joint strength when executing Tig welding on austenitic steel , several critical practices must be adhered to .
