Pioneering Excellence in Welding Solutions Since 2004
Established in Wulian, Rizhao City, Shandong Province, Wulian Yuxin Hardware Equipment Co., Ltd. has grown from a locally excellent manufacturer to a globally recognized producer of premium welding consumables. With our own 15,000-square-meter production facility and advanced manufacturing equipment, we proudly maintain complete control over our production processes, ensuring consistent quality across our entire product range.
By investing continuously in state-of-the-art wire drawing lines, chemical analysis labs, and precision copper-coating workshops, we provide global bulk buyers with premium SG2 (ER70S-6) welding wires, flux-cored wires, and stainless steel wire consumables. Our team aligns our operation with international quality frameworks to exceed expectations in dynamic assembly lines.
A comprehensive guide to material specifications, metallurgy parameters, and macro applications for international procurement officers.
SG2 carbon steel wires (EN ISO 14341-A G 3Si1) require precise control of Silicon (0.80% - 1.15%) and Manganese (1.40% - 1.85%) to ensure high deoxidation in the molten pool, mitigating pore formation and maximizing tensile strength.
Through our proprietary chemical cleaning process post wire-drawing, we reduce surface residue. This prevents arc instability and significantly decreases post-weld cleanup time on heavy machinery parts.
Utilizing Layer Precision Winding (LPW), our SG2 spools bypass typical tangles that trigger downtime in high-efficiency robotic welding lines. Ideal for continuous, unattended workshop usage.
Understanding standard mappings simplifies selection for complex engineering projects. Below is a comparative guide showing standard certifications for Wulian Yuxin products:
| Common Standard Name | AWS A5.18 Code | EN ISO 14341-A Code | Shielding Gas Requirement | Tensile Strength (MPa) | Yield Strength (MPa) |
|---|---|---|---|---|---|
| SG2 Solid Wire | ER70S-6 | G 3Si1 / G 42 4 M21 3Si1 | 100% CO2 or Ar-CO2 Blends | 500 - 640 | ≥ 420 |
| E71T Flux-Cored | E71T-1C / 1M | T 46 2 P C1 1 H5 | 100% CO2 | 480 - 660 | ≥ 400 |
| Stainless Steel Wire | ER308L / ER316L | G 19 9 L / G 19 12 3 L | Argon + 2% O2 / CO2 | 510 - 690 | ≥ 350 |
For modern procurement officers, securing a reliable flow of wholesale SG2 welding consumables requires managing container shipping timelines, compliance standards, and mechanical variance. Wulian Yuxin offers targeted systems to optimize these pipelines:
