DUAL SHIELD 8100W DUAL SHIELD 7100 ULTRA An all-position flux cored wire for welding type weathering steels Classification $ Print AWS A5.20, Classification $ Print AWS A5.29: E80T1-W E71T-1/E71T-9/E71T-9M DESCRIPTION ESAB Dual Shield 7100 Ultra is an all-position flux cored electrode designed for optimum performance when using 100% CO2 shielding. The smooth metal transfer facilitates easy deposition of vertical-up stringer beads. Fillet contour is flat slightly convex with equal leg lengths and uniform sidewall welling. The slag coverage is complete and designed for easy removal. Weldmetal is consistently free of inclusions and porosity for X-ray soundness. WELDING CURRENT: DC + DESCRIPTION Dual Shield 8100W is an all-position flux cored wire developed specifically to meet the demand for weld deposits that colour match the low alloy, high strength weathering grade steels. Field testing on U.S.S. Cor-Ten showed that, after atmospheric exposure, there was no discernible difference between the colour of the weldmetal and the base metal. This electrode displays good operator appeal and produces high strength deposits. It is an ideal choice for structural applications where the architectural “weathering look” is of importance.
