Ti Alloy TIG Fabrication: Difficulties and Solutions
Welding titanium with the gas tungsten arc process presents specific problems beyond those encountered with ferrous metals. The alloy's high reactivity, leading to film formation that can cause inclusions and reduced toughness, is a critical concern. Furthermore, titanium's reduced thermal conductivity makes managing the heat-affected zone pipe bending difficult. Remedies require meticulous degreasing to remove contaminants before and during welding, employing shielding gases like Ar or a helium mix to inhibit oxidation, and utilizing careful welding parameters – including lower voltage and correct feed rates. Proper method and expertise are vital for reliable Ti alloy welding.
Stainless Steel Tig Welding: Ensuring Strength
