Ti Alloy Gas Tungsten Arc Welding: Difficulties and Approaches
Welding titanium with the gas tungsten arc process presents distinct difficulties beyond those encountered with steel. The metal's high reactivity, leading to oxide formation that can cause voids and poor formability, is a critical concern. Furthermore, titanium's reduced thermal response makes controlling the HAZ problematic. Approaches require meticulous cleaning to remove oxides before and during fabrication, employing inert gases like pure argon or He to minimize reaction, and utilizing precise settings – including reduced voltage and correct welding rates. Adequate procedure and expertise are crucial for high-quality Ti alloy fabrication.
