IRONWELD ER70S-6 Mild Steel TIG Welding Wire
Precision-drawn AWS A5.18 ER70S-6 solid TIG wire, engineered for clean, X-ray quality welds on mild and low carbon steel. The 1.6mm diameter suits general fabrication through to medium plate thickness, giving fabricators a versatile rod for structural, pipe, and general workshop welding.
Why choose this wire:
ER70S-6 carries higher manganese and silicon content than standard carbon steel wires, giving it stronger deoxidizing power. That matters in real workshop conditions: it welds cleanly through light mill scale, surface rust, or oil residue where a standard wire would porosity out. The extra silicon also boosts weld pool fluidity, producing a smoother, flatter bead profile and cutting down on post-weld grinding time.
Certification:
This wire holds classification approvals from Lloyd's Register (LR), American Bureau of Shipping (ABS), and Bureau Veritas (BV), alongside other major marine and structural classification bodies. These are the certifications shipyards, pressure vessel fabricators, and structural steel contractors ask for on their Material Test Certificates (MTC), since welds on classed vessels or structures must trace back to an approved consumable. For a wholesaler, stocking a wire with this certification spread means you can supply both general trade customers and compliance-driven industries (marine, construction, heavy engineering) off the same product.
Specifications:
Classification: AWS A5.18 ER70S-6 (also referenced as SG2, G3Si1, YGW12 depending on standard)
