Titanium Gas Tungsten Arc Joining: Problems and Approaches
Welding Ti with the TIG process presents specific difficulties beyond those encountered with carbon steel. The material's elevated reactivity, producing oxide formation that can cause inclusions and poor toughness, is a major concern. Furthermore, titanium's minimal thermal conductivity makes controlling the weld pool problematic. Approaches include meticulous degreasing to remove oxides before and during welding, employing protective atmospheres like pure argon or helium to minimize reaction, and utilizing controlled welding parameters – including lower power and correct travel speeds. Proper procedure and experience are vital for successful Ti joining.
