Ti Alloy GTAW Joining: Challenges and Solutions
Welding titanium with the TIG process presents unique difficulties beyond those encountered with ferrous metals. The alloy's elevated reactivity, leading to oxide formation that can cause voids and poor ductility, is a principal concern. Furthermore, titanium's minimal thermal conductivity makes regulating the heat-affected zone challenging. Remedies require meticulous preparation to remove oxides before and during fabrication, employing shielding gases like pure argon or helium to minimize oxidation, and utilizing precise welding parameters – including lower amperage and correct travel speeds. Proper technique and skill are crucial for reliable Ti fabrication.
