Product Details
ER70S-2 is a solid welding wire designed for use in TIG (Gas Tungsten Arc Welding) and MIG (Gas Metal Arc Welding) processes. It is primarily used for welding carbon steels and low-alloy steels, offering excellent mechanical properties and strong welds. The "ER" in its name stands for "Electrode or Rod," indicating that it can be used as either a filler rod for TIG or a wire electrode for MIG. The "70" signifies a minimum tensile strength of 70,000 psi, ensuring good structural integrity, while the "S" denotes that it is a solid wire, not flux-cored. The "-2" indicates the specific deoxidizer formulation in the wire, which sets it apart from other wires like ER70S-3 or ER70S-6. One of the key advantages of ER70S-2 is its triple deoxidizer system, typically consisting of aluminum, titanium, and zirconium. These elements allow the wire to perform well even on steels that are not perfectly clean, such as those with mill scale, rust, or oil residue. This makes it particularly suitable for root pass welding or for use in situations where surface preparation may be less than ideal. The deoxidizers help prevent porosity and improve arc stability, resulting in clean, high-quality welds with minimal defects. This filler wire is widely used in a variety of industries, including automotive manufacturing, pipeline construction, pressure vessel fabrication, and structural steelwork. It is suitable for both single-pass and multi-pass welding, and it provides a smooth weld bead with good ductility and impact resistance. These characteristics make ER70S-2 a reliable choice for many critical and general-purpose welding applications.
