Titanium TIG Fabrication: Challenges and Solutions
Welding Ti alloys with the TIG process presents distinct challenges beyond those encountered with carbon steel. The material's significant reactivity, resulting film formation that can cause inclusions and poor toughness, is a principal concern. Furthermore, titanium's reduced thermal heat transfer makes controlling the HAZ problematic. Solutions require meticulous cleaning to remove scale before and during fabrication, employing protective atmospheres like argon or He to minimize scale formation, and utilizing careful conditions – including decreased voltage and correct feed rates. Correct technique and experience are vital for reliable Ti alloy fabrication.
Stainless Steel Tig Welding: Maximizing Strength
To guarantee maximum joint strength when conducting Tig welding on stainless steel , several important practices must be followed .
