Ti TIG Fabrication: Challenges and Solutions
Welding Ti alloys with the TIG process presents distinct challenges beyond those encountered with steel. The alloy's elevated reactivity, producing film formation that can cause inclusions and reduced toughness, is a critical concern. Furthermore, titanium's reduced thermal heat transfer makes controlling the HAZ challenging. Approaches require meticulous degreasing to remove scale before and during joining, employing shielding gases like pure argon or helium to minimize scale formation, and utilizing careful settings – including lower power and suitable feed rates. Correct procedure and expertise are essential for successful Ti fabrication.
304 Stainless Tig Welding: Ensuring Strength
To secure maximum joint strength when executing Tig welding on stainless steel , several important practices must be adhered to .
