What is AWS Class ERTI-12 MIG and TIG Filler Rod Welding Wire ?

AWS Class ERTi-12 filler metal is a titanium alloy that mainly consists of titanium, with minor additions of 0.3% molybdenum and 0.8% nickel. This combination significantly boosts corrosion resistance, especially in mildly reducing environments like nitric and sulfuric acids. ERTi-12 boasts a tensile strength of approximately 483–586 MPa (70–85 ksi), along with excellent ductility and good weldability. Its enhanced resistance to crevice corrosion and stress corrosion cracking makes it a reliable option for challenging service conditions. ERTi-12 meets ASTM B863 standards, making it perfect for applications that demand both corrosion protection and mechanical strength.
