Ti Gas Tungsten Arc Joining: Difficulties and Remedies
Welding titanium with the TIG process presents specific problems beyond those encountered with ferrous metals. The material's elevated reactivity, leading to scale formation that CNC machining parts can cause voids and brittle ductility, is a critical concern. Furthermore, the alloy's reduced thermal heat transfer makes managing the weld pool problematic. Approaches require meticulous cleaning to remove scale before and during welding, employing shielding gases like pure argon or helium to minimize reaction, and utilizing precise conditions – including decreased voltage and suitable feed rates. Correct procedure and skill are vital for successful Ti alloy welding.
