Weathering Steel Welding Wire

Our company produces two main series of weathering steel welding wires: gas shielded welding wire and submerged arc welding wire. The products have advantages such as strength, toughness, ductility, corrosion resistance, high temperature resistance, and fatigue resistance.

Our Weathering Steel Welding Wire includes two main series: Gas Shielded Welding Wire (MIG) and Submerged Arc Welding Wire (SAW).

Designed for welding weathering steels, the deposited metal features excellent toughness, ductility, corrosion resistance, high-temperature resistance, and fatigue resistance. It is ideal for steel structures exposed to harsh atmospheric environments over long periods.
