Ti Alloy TIG Fabrication: Problems and Solutions
Welding Ti alloys with the GTAW process presents distinct problems beyond those encountered with steel. The material's significant reactivity, producing scale formation that can cause voids and poor toughness, is a major concern. Furthermore, titanium's reduced thermal conductivity makes regulating the weld pool problematic. Remedies require meticulous degreasing to remove oxides before and during fabrication, employing inert gases like argon or helium to inhibit scale formation, and utilizing precise settings – including reduced voltage and suitable travel speeds. Proper technique and experience are essential for successful Ti alloy joining.
