Ti GTAW Welding: Problems and Approaches
Welding Ti with the GTAW process presents specific challenges beyond those encountered with steel. The metal's elevated reactivity, resulting film formation that can cause voids and reduced toughness, is a major concern. Furthermore, the alloy's reduced thermal heat transfer makes managing the heat-affected zone problematic. Remedies involve meticulous cleaning to remove scale before and during welding, employing shielding gases like pure argon or a helium mix to inhibit reaction, and utilizing stainless steel welding controlled settings – including decreased voltage and appropriate feed rates. Adequate procedure and experience are essential for successful Ti welding.
