9 Cored Wire Welding The flux-cored electrode is a continuous, tubular electrode wire, with a sheath of low carbon, mild steel and core containing deoxidizers, slag formers and arc stabilizers in powder form. Both strip and core materials are carefully monitored to conform with rigorous specifications. Automatic controls during production pro- vide a uniform, high quality product. Flux-cored wires are specifically designed to weld mild steel using either CO2 gas or Argon-Co2 gas mixtures. Flux-cored arc welding offers many inherent advantages over stick electrode welding. Higher deposition rates (typically double) and increased duty cycles (no electrode changing) mean savings in labor costs. The deeper penetration achieved with cored wire also permits less joint preparation, yet provides quality welds free from lack of fusion and slag entrapment. Also flux-cored wire welding is easy to learn.
