Titanium TIG Welding: Problems and Solutions
Welding titanium with the gas tungsten arc process presents distinct challenges beyond those encountered with carbon steel. The material's high reactivity, producing scale formation that can cause voids and poor formability, is a major concern. Furthermore, titanium's low thermal response makes controlling the heat-affected zone challenging. Remedies involve meticulous cleaning to remove scale before and during joining, employing protective atmospheres like pure argon or He to inhibit oxidation, and utilizing careful settings – including decreased power and correct feed rates. Proper method and skill are vital for successful Ti alloy joining.
