Ti Alloy TIG Joining: Problems and Approaches
Welding Ti alloys with the TIG process presents unique challenges beyond those encountered with carbon steel. The material's elevated reactivity, producing film formation that can cause porosity and poor formability, is a critical concern. Furthermore, titanium's reduced thermal heat transfer makes managing the weld pool challenging. Remedies include meticulous degreasing to remove scale before and during fabrication, employing inert gases like argon or helium to prevent oxidation, and utilizing careful settings – including reduced power and appropriate travel speeds. Proper technique and expertise are essential for reliable titanium joining.
