AWS A5.29 CLASS E 81T1-Ni1
E81T1-Ni1 is a titania slag formulation flux cored wire for single or multi-pass flat or fillet welds on medium and heavy thickness 1% nickel steel plate used in petro-chemical construction, mining and earth-moving equipment, and for weathering steels where color-match is not required. E81T1-Ni1 is noted for its high disposition rates, low spatter generation, ease of slag removal, and excellent weld bead appearance. The shield gas recommended is 100% CO2.
E81T1-Ni is used extensively in the fabrication, erection, and repair of structural fabrication of higher strength. Steels having a 70,000-80,000 psi tensile strength. The weld metal analysis of the deposit is similar to E8018-C3 low hydrogen electrodes. The weld deposits are smooth and have deep penetration. E81T1-Ni1 is noted for its smooth arc and minimum spatter. When used for horizontal fillet joints the weld bead has
