Ti Alloy GTAW Welding: Difficulties and Approaches
Welding Ti alloys with the TIG process presents unique problems beyond those encountered with carbon steel. The material's high reactivity, leading to oxide formation that can cause porosity and brittle ductility, is a major concern. Furthermore, titanium's low thermal heat transfer makes regulating the weld pool difficult. Remedies involve meticulous cleaning to remove scale before and during welding, employing protective atmospheres like argon or a helium mix to inhibit reaction, and utilizing careful conditions – including decreased power and appropriate welding rates. Correct method and skill are vital for reliable Ti alloy joining.
