Titanium TIG Fabrication: Difficulties and Solutions
Welding titanium with the TIG process presents specific difficulties beyond those encountered with ferrous metals. The metal's significant reactivity, resulting film formation that can cause voids and brittle formability, is a critical concern. Furthermore, Ti's reduced thermal heat transfer makes controlling the weld pool problematic. Solutions include meticulous cleaning to remove oxides before and during welding, employing inert gases like pure argon or a helium mix to minimize oxidation, and utilizing careful welding parameters – including decreased voltage and suitable feed rates. Proper method and skill are vital for successful Ti alloy welding.
