Ti TIG Welding: Challenges and Remedies
Welding Ti with the gas tungsten arc process presents specific problems beyond those encountered with steel. The alloy's high reactivity, producing oxide formation that can cause inclusions and poor formability, is a critical concern. Furthermore, titanium's reduced thermal heat transfer makes managing the heat-affected zone problematic. Solutions require meticulous cleaning to remove oxides before and during fabrication, employing inert gases like Ar or a helium mix to inhibit reaction, and utilizing precise settings – including reduced voltage and correct feed rates. Proper procedure and expertise are vital for high-quality titanium joining.
Austenitic Steel Tig Welding: Achieving Strength
