What is AWS Class ERTI-12 MIG & TIG?
The AWS Class ERTi-12 filler wire is made from commercially pure titanium, with a touch of nickel and molybdenum added. This unique blend boosts corrosion resistance, especially in reducing and mildly acidic environments, while still providing good strength and ductility. The weld metal produced shows moderate tensile strength, excellent elongation, and reliable toughness. ERTi-12 ensures stable arc characteristics, a smooth weld bead finish, and good metallurgical compatibility when used with the right shielding gas control.
