Ti TIG Joining: Challenges and Remedies
Welding titanium with the GTAW process presents unique challenges beyond those encountered with steel. The alloy's significant reactivity, resulting scale formation that can cause inclusions and poor ductility, is a critical concern. Furthermore, the alloy's minimal thermal heat transfer makes regulating the weld pool challenging. Remedies involve meticulous cleaning to remove contaminants before and during joining, employing protective atmospheres like Ar or helium to inhibit oxidation, and utilizing careful settings – including lower amperage and suitable travel speeds. Proper technique and experience are vital for high-quality Ti alloy joining.
Stainless Steel Tig Welding: Maximizing Strength
