Detailed Description

An extension of our superior line of carbon steel UltraCore products, 81Ni1A75-H is designed for high strength, low-alloy applications using 75% argon/25% CO2. The use of mixed shielding gas stabilizes arc characteristics, reduces spatter levels, and washes out the weld bead for a flat appearance. These electrodes exhibit robust impact properties, even with a notch offset of 2.5 mm from weld centerline, as well as superior crack resistance, due to low diffusible hydrogen levels (4 mL/100 g of weld deposit max). This electrode is ideally suited to replace E8018-C3 stick electrodes for added efficiency and increased productivity in bridge fabrication, offshore work, or structural fabrication
