Coreshield 7 flux cored wire is a self-shielded wire designed for single or multiple pass welding of mild steel when impact toughness is not a requirement. The high deposition rate can be successfully translated into fast travel speeds. The DCEN (electrode negative) operation is characterized by a spray-like transfer and a wetting slag which make it ideal for lap and step-up fillet welds. The crumbly slag is easily removed with light scraping; the weld bead is slightly convex. The smaller diameters can be applied vertically down on 10 gauge (3.5 mm) and thicker steels. Coreshield 7 is ideally suited for structural steel applications where no seismic requirements are specified.
