Ti GTAW Fabrication: Difficulties and Solutions
Welding titanium with the TIG process presents distinct challenges beyond those encountered with carbon steel. The metal's high reactivity, resulting film formation that can cause inclusions and reduced formability, is a critical concern. Furthermore, titanium's minimal thermal response makes managing the heat-affected zone difficult. Solutions include meticulous cleaning to remove scale before and during fabrication, employing shielding gases like pure argon or a helium mix to minimize scale formation, and utilizing controlled conditions – including reduced power and suitable travel speeds. Adequate technique and expertise are essential for reliable titanium fabrication.
