Titanium TIG Welding: Problems and Solutions
Welding Ti alloys with the TIG process presents distinct challenges beyond those encountered with ferrous metals. The material's elevated reactivity, resulting scale formation that can cause voids and reduced ductility, is a critical concern. Furthermore, titanium's reduced thermal heat transfer makes managing the heat-affected zone challenging. Remedies require meticulous cleaning to remove oxides before and during welding, employing protective atmospheres like Ar or He to inhibit scale formation, and utilizing careful settings – including decreased voltage and correct travel speeds. Correct procedure and experience are crucial for reliable Ti alloy joining.
