Ti Alloy TIG Fabrication: Problems and Approaches
Welding Ti alloys with the GTAW process presents specific difficulties beyond those encountered with carbon steel. The material's high reactivity, resulting scale formation that can cause voids and poor ductility, is a major concern. Furthermore, the alloy's reduced thermal conductivity makes controlling the weld pool challenging. Solutions require meticulous degreasing to remove contaminants before and during fabrication, employing shielding gases like argon or helium to minimize scale formation, and utilizing precise conditions – including reduced voltage and appropriate travel speeds. Adequate technique and skill are crucial for reliable titanium welding.
Austenitic Steel Tig Welding: Ensuring Strength
To obtain superior joint strength when conducting Tig welding on austenitic steel , several important practices must be followed .
