Ti Alloy GTAW Fabrication: Difficulties and Approaches
Welding Ti with the TIG process presents unique difficulties beyond those encountered with ferrous metals. The metal's high reactivity, resulting scale formation that can cause porosity and poor ductility, is a major concern. Furthermore, titanium's minimal thermal response makes managing the weld pool problematic. Approaches involve meticulous degreasing to remove contaminants before and during welding, employing inert gases like pure argon or He to minimize reaction, and utilizing controlled settings – including lower power and correct welding rates. Proper technique and expertise are crucial for successful Ti joining.
Austenitic Steel Tig Welding: Maximizing Strength
To secure superior joint strength when performing Tig welding on 304 stainless, several critical practices must be followed .
