Ni-Cr-Mo Welding Electrodel
INCONEL Welding Electrode 122 is used for shielded-metal-arc welding of INCONEL alloys 622 and 625, INCOLOY alloy 25-6MO, and INCOLOY alloy 825. This is an excellent dissimilar metal welding electrode that offers protection against preferential weld metal corrosion when used for joining molybdenum-containing stainless steels, INCONEL alloy C-276, and INCONEL alloy 625. It is a versatile welding product for the chemical, power, petroleum, and marine industries.
The electrodes provide excellent operability for groove and fillet welding in the downhand position and the smaller diameter electrodes are also suitable for all position welding. Power supply: direct current, electrode positive.
