Titanium Gas Tungsten Arc Welding: Difficulties and Approaches
Welding Ti alloys with the gas tungsten arc process presents distinct difficulties beyond those encountered with carbon steel. The alloy's high reactivity, resulting film formation that can cause porosity and poor formability, is a critical concern. Furthermore, the alloy's reduced thermal heat transfer makes regulating the HAZ problematic. Solutions require meticulous degreasing to remove contaminants before and during welding, employing protective atmospheres like argon or He to minimize scale formation, and utilizing controlled conditions – including lower voltage and appropriate travel speeds. Proper procedure and skill are vital for successful Ti joining.
