Ti Alloy GTAW Welding: Challenges and Solutions
Welding Ti alloys with the TIG process presents distinct challenges beyond those encountered with carbon steel. The material's high reactivity, producing oxide formation that can cause voids and poor formability, is a major concern. Furthermore, the alloy's low thermal heat transfer makes managing the weld pool problematic. Approaches involve meticulous preparation to remove scale before and during fabrication, employing shielding gases like pure argon metal stamping or He to minimize scale formation, and utilizing precise settings – including lower power and appropriate feed rates. Proper method and skill are crucial for reliable Ti welding.
