Explore our core product lineup featuring optimized metallurgy, strict tolerances, and global structural compliance certifications.
Founded in 2004 in Wulian, Rizhao City, Shandong Province, Wulian Yuxin Hardware Equipment Co., Ltd. has evolved from a regional pioneer to a high-capacity, technology-oriented global exporter. We specialize in producing premium structural welding consumables, engineered to withstand high pressure, sub-zero working temperatures, and structural fatigue.
With a massive 15,000-square-meter modern factory floor, we manage the complete wire drawing, straightening, surface pickling, and packaging processes in-house. This comprehensive manufacturing integration guarantees that our flagship TIG Welding Bundle 5kg offerings maintain absolute trace metallurgical homogeneity, uniform copper-layer thickness, and zero surface-level contaminant values.
Fully certified by ISO9001 and CE frameworks.
Wire straightness & thickness controlled under ±0.02mm.
Gas Tungsten Arc Welding (GTAW / TIG) requires exceptionally pure welding wire formulations to prevent slag inclusions, micro-porosity, and unstable arcs. Our TIG Welding Rods (available in 5kg bundles) are manufactured with premium wire rods and optimized levels of Silicon (Si) and Manganese (Mn) as primary deoxidizers.
This composition guarantees an ultra-clean weld pool and exceptional fluid control under pure Argon shielding gas. For specialized stainless steel (such as ER308L / ER316L) and carbon steel (ER70S-6) grades, Yuxin’s proprietary thermal processing steps align the grain boundaries of the material, providing high crack resistance in structural fabrication.
| Alloy Grade | AWS Spec | C (%) | Mn (%) | Si (%) |
|---|---|---|---|---|
| ER70S-6 | AWS A5.18 | 0.06 - 0.15 | 1.40 - 1.85 | 0.80 - 1.15 |
| ER308L | AWS A5.9 | ≤ 0.03 | 1.00 - 2.50 | 0.30 - 0.65 |
| ER316L | AWS A5.9 | ≤ 0.03 | 1.00 - 2.50 | 0.30 - 0.65 |
Analyzing key supply challenges, logistical specifications, and strategic solutions for modern high-precision welding operations.
TIG wire bundles are highly susceptible to ambient humidity and oxidation, which leads to hydrogen cracking. Yuxin supplies all 5kg bundles in triple-sealed plastic canisters, containing silica-gel desiccants inside protective external structural cartons.
Manual or hot-wire TIG processes require exceptionally straight rods to prevent wire-stalling or erratic arc behavior. Yuxin utilizes precision multi-roller rotary straightening processes, ensuring straightness deviation is below 0.5mm per meter.
Global oil & gas, pressure vessel, and infrastructure projects demand complete mill test certificates (MTC) for each batch. Wulian Yuxin offers full chemical trace identification from ladle analysis down to final bundle shipping labels.
