Ti Alloy TIG Joining: Challenges and Solutions
Welding stainless steel welding Ti alloys with the GTAW process presents specific problems beyond those encountered with steel. The material's high reactivity, resulting scale formation that can cause voids and brittle toughness, is a major concern. Furthermore, the alloy's reduced thermal response makes controlling the weld pool problematic. Remedies involve meticulous cleaning to remove contaminants before and during joining, employing shielding gases like Ar or He to inhibit reaction, and utilizing controlled settings – including lower power and correct feed rates. Proper technique and skill are crucial for successful Ti fabrication.
