Titanium Gas Tungsten Arc Fabrication: Problems and Approaches
Welding Ti with the GTAW process presents distinct challenges beyond those encountered with steel. The metal's significant reactivity, producing film formation that can cause voids and brittle formability, is a major concern. Furthermore, Ti's minimal thermal heat transfer makes controlling the heat-affected zone problematic. Approaches require meticulous cleaning to remove contaminants before and during fabrication, employing inert gases like argon or He to prevent reaction, and utilizing careful conditions – including reduced power and appropriate welding rates. Adequate technique and experience are vital for successful Ti fabrication.
