Titanium GTAW Fabrication: Difficulties and Solutions
Welding Ti alloys with the TIG process presents unique difficulties beyond those encountered with ferrous metals. The alloy's high reactivity, leading to oxide formation that can cause voids stainless steel welding and brittle formability, is a major concern. Furthermore, titanium's reduced thermal conductivity makes controlling the heat-affected zone problematic. Solutions require meticulous degreasing to remove oxides before and during joining, employing shielding gases like argon or helium to inhibit scale formation, and utilizing careful welding parameters – including lower amperage and correct travel speeds. Correct procedure and expertise are crucial for reliable Ti welding.
Stainless Steel Tig Welding: Maximizing Strength
