Esab Coreshield 11 description: Coreshield 11 is an all-position self-shielded flux cored welding wire meeting all requirements for the E71T-11 classification. Coreshield 11 is excellent for use on single or multiple pass lap, fillet and butt welds on mild steels in all welding positions. Limitations do exist for multipass welds in excess of 1/2 in (12.7 mm). It produces smooth arc action, full slag coverage, easy slag removal, and low spatter. This product should find excellent acceptance in general purpose mild steel fabrication. In structural fabrication, the product can be used where no seismic requirements are present. Coreshield 11 is run DCEN.
