Ti GTAW Welding: Problems and Remedies
Welding Ti alloys with the gas tungsten arc process presents unique problems beyond those encountered with ferrous metals. The alloy's elevated reactivity, resulting film formation that can cause inclusions and reduced formability, is a principal concern. Furthermore, Ti's reduced thermal heat transfer makes managing the weld pool challenging. Remedies involve meticulous degreasing to remove scale before and during welding, employing protective atmospheres like Ar or helium to minimize scale formation, and utilizing precise conditions – including lower voltage and appropriate travel speeds. Correct procedure and experience are essential for reliable titanium welding.
