Titanium Gas Tungsten Arc Fabrication: Problems and Approaches
Welding titanium with the GTAW process presents specific challenges beyond those encountered with steel. The metal's significant reactivity, resulting scale formation that can cause voids and brittle ductility, is a major concern. Furthermore, Ti's low thermal conductivity makes controlling the heat-affected zone problematic. Approaches involve meticulous degreasing to remove scale before and during fabrication, employing shielding gases like pure argon or He to minimize reaction, and utilizing careful conditions – including lower power and appropriate feed rates. Correct method and skill are crucial for reliable Ti alloy fabrication.
