AWS A5.11 ENiCrMo-3
Nickel Base Alloy, Coated Electrode — INCONEL® Welding Electrode 112
INCONEL® Welding Electrode 112
INCONEL® Welding Electrode 112 is used for shielded-metal-arc welding of INCONEL® alloy 625, INCOLOY alloy 825, INCOLOY alloy 25-6MO, and other molybdenum-corrosion- resistant alloys such as alloy 20. The weld metal has high strength at room and elevated temperatures and has exceptional corrosion resistance, including resistance to pitting, crevice corrosion, and polythionic acid stress-corrosion cracking. INCONEL® Welding electrode 112 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 filet welding in the downhand position and the smaller diameter electrodes are also suitable for all position welding. Power supply: direct current, electrode positive.

HAYNES® 112 Welding Electrodes
HAYNES® 112 Welding Electrodes are used for the shielded metal arc welding of 625, 825 and molybdenum-containing alloys. The weld metal has good resistance to corrosion including pitting and crevice corrosion. In addition, the electrodes are useful for overlay and cladding of various grades of steel including stainless, low alloy and carbon steels. The electrode makes a great dissimilar joining electrode when joining HAYNES® and HASTELLOY® materials to stainless and carbon steels. The coating is designed for great operability, especially out-of-position welding.
