Ti Gas Tungsten Arc Fabrication: Challenges and Approaches
Welding titanium with the TIG process presents unique problems beyond those encountered with ferrous metals. The alloy's elevated reactivity, leading to scale formation that can cause inclusions and reduced toughness, is a critical concern. Furthermore, titanium's reduced thermal response makes regulating the heat-affected zone difficult. Approaches include meticulous degreasing to remove scale before and during joining, employing inert gases like argon or a helium mix to inhibit reaction, and utilizing careful welding parameters – including decreased voltage and correct welding rates. Correct technique and expertise are vital for high-quality Ti joining.
