Ti Gas Tungsten Arc Fabrication: Difficulties and Approaches
Welding titanium with the gas tungsten arc process presents unique challenges beyond those encountered with steel. The metal's high reactivity, producing scale formation that can cause voids and poor formability, is a major concern. Furthermore, Ti's minimal thermal conductivity makes regulating the HAZ challenging. Remedies involve meticulous preparation to remove scale before and during fabrication, employing shielding gases like pure argon or He to inhibit scale formation, and utilizing controlled welding parameters – including reduced amperage and appropriate welding rates. Adequate technique and expertise are crucial for reliable Ti alloy joining.
