Ti GTAW Joining: Difficulties and Remedies
Welding Ti with the TIG process presents unique problems beyond those encountered with ferrous metals. The alloy's significant reactivity, leading to scale formation that can cause porosity and poor ductility, is a principal concern. Furthermore, titanium's minimal thermal conductivity makes managing the weld pool difficult. Approaches involve meticulous degreasing to remove contaminants before and during welding, employing protective atmospheres like pure argon or He to minimize scale formation, and utilizing controlled welding parameters – including reduced power and appropriate feed rates. Correct procedure and skill are vital for successful titanium fabrication.
