Ni-Cr-Mo Filler Metal
INCONEL Filler Metal 622 is used for gas-tungsten-arc and gas-metal-arc welding of INCONEL alloys 22 and 625, INCOLOY alloy 25-6MO, and INCOLOY alloy 825. This is also an excellent dissimilar metal welding product that offers protection against preferential weld metal corrosion when used for joining molybdenum-containing stainless steels, INCONEL alloy C-276, and INCONEL alloy 625. The high chromium content, along with the tungsten and molybdenum, give good resistance to pitting and crevice corrosion. INCONEL Filler Metal 622 is useful for many dissimilar joints involving INCONEL and INCOLOY alloys, and carbon, low-alloy and stainless steels. Submerged arc welding and overlaying can be done with INCOFLUX NT120 Submerged Arc Flux.
