ER70S-6 is the most common and versatile choice for MIG (GMAW) welding of mild steel. But selecting the right diameter is crucial for achieving strong, clean welds and maximizing productivity.Your choice should be a strategic balance of four key factors:1. Material Thickness (The Primary Factor): Ma

Do you know that the diameter tolerance of your welding wire is a critical factor for welding performance? It directly impacts arc stability, wire feeding smoothness, and the final quality of your weld. Furthermore, the tolerance standards are not the same for solid and flux-cored wires. 1. Toleranc

When selecting a carbon steel welding wire like ER70S-6, a key decision is choosing between traditional copper-coated wire and the newer copper-free alternative. There's no outright "best" choice—only the right one for your specific application. Let's break it down!

Upon the arrival of raw materials at our Szeshang Welding factory, we conduct random sampling to test their chemical composition and mechanical properties.This ensures that all materials meet our strict production standards for manufacturing welding wire and welding electrode.Check out some laborato
