Import Aws Er70s-6 Copper Coated Welding Wire — Buy in Bulk from Supplier in China

The AWS ER70S-6 copper coated welding wire from Dezhou Deming Welding Material Co., Ltd is a mild steel MIG and TIG filler metal designed for industrial welding applications requiring high performance. It meets AWS A5.18 specification, with a copper coating that enhances electrical conductivity and arc stability, reducing spatter and improving feedability. The wire is supplied in spools suitable for automated and semi-automated welding systems, with diameters tailored for precision work.

This ER70S-6 variant contains elevated levels of manganese and silicon deoxidizers, which improve wettability and produce smooth, strong weld beads with minimal slag. Typical chemical composition includes 0.06-0.15% carbon, 1.40-1.85% manganese, and 0.80-1.15% silicon, with the copper coating adding 0.1-0.3% by weight. The wire is standard for joining carbon and low-alloy steels in automotive, construction, and heavy fabrication sectors where clean, reliable welds are critical.

Industrial buyers source this wire for structural steel fabrication, pipeline welding, and repair work where AWS compliance is mandatory. Dezhou Deming Welding Material Co., Ltd operates from Shandong, with a planned annual productivity of 12,000 tons, catering to bulk orders. Buyers should confirm spool sizes, diameter tolerances, and packaging specifications, as these can vary by order volume and application. The wire is compatible with CO2, argon, or mixed gas shielding for versatile use.

Dezhou Deming Welding Material Co., Ltd is based in Chuangye Road, Dezhou, Shandong, China, with a focus on manufacturing AWS-compliant welding consumables. The company has operated since 2001, with a significant investment of RMB 30 million in production capacity, reflecting its long-term commitment to the welding materials sector. Its harbor-tier trust status indicates a verified operational presence, though current response metrics are not available.

The supplier specializes in copper-coated welding wires, including the ER70S-6 grade, and serves industries where precision and compliance with international standards are non-negotiable. While the profile does not list certifications like ISO or SGS, buyers are advised to request documentation for quality assurance. The company’s planned annual output of 12,000 tons suggests capacity for large-scale orders, but specific lead times and MOQs must be confirmed directly with the supplier.
