Alloy 112 Welding Electrode is used for shielded-metal-arc welding of INCONEL® alloy 625, INCOLOY® alloy 825, INCOLOY® alloy 25-6MO, and other molybdenum-contain¬ing stainless steels. It is also used for surfacing of steel and for welding various corrosion-resistant alloys such as alloy 20. The weld metal has high strength at room and elevated tem¬peratures and has exceptional corrosion resistance, including resistance to pitting, crevice corrosion, and polythionic acid stress-corrosion cracking. Alloy 112 Welding Electrode is useful for many dissimilar joints involving INCONEL® alloys, INCOLOY® alloys, stainless steels, low-alloy steels, and carbon steels.
The electrodes provide excellent operability for groove and fillet welding in the downhand position and the electrodes through 3.2 size diameter are suitable for all position welding.
Power supply: direct current, electrode positive.
