Ti Alloy Gas Tungsten Arc Joining: Difficulties and Solutions
Welding Ti with the TIG process presents distinct difficulties beyond those encountered with carbon steel. The material's elevated reactivity, resulting scale formation that can cause inclusions and poor ductility, is a major concern. Furthermore, titanium's minimal thermal conductivity makes managing the heat-affected zone problematic. Solutions include meticulous cleaning to remove contaminants before and during welding, employing inert gases like pure argon or He to prevent reaction, and utilizing controlled conditions – including decreased power and suitable welding rates. Correct procedure and skill are essential for reliable titanium welding.
Stainless Steel Tig Welding: Maximizing Strength
To secure maximum joint strength when performing Tig welding on 304 stainless, several important practices must be observed.
