Ti Gas Tungsten Arc Fabrication: Challenges and Remedies
Welding titanium with the GTAW process presents unique problems beyond those encountered with steel. The alloy's elevated reactivity, resulting oxide formation that can cause porosity and poor formability, is a major concern. Furthermore, the alloy's minimal thermal heat transfer makes regulating the heat-affected zone difficult. Solutions involve meticulous degreasing to remove oxides before and during fabrication, employing shielding gases like pure argon or helium to prevent scale formation, and utilizing controlled welding parameters – including lower voltage and correct feed rates. Adequate technique and expertise are crucial for successful Ti alloy joining.
