Ni-190
AWS/SFA5.11 Class ENiCu-7 UNS W84190
Washington Alloy 190 flux-coated electrodes are designed for shielded metal arc welding of nickel-copper Monel® 400 and 404 to themselves and to steel. This electrode is perfect for joining many nickel copper alloys to copper, copper-nickel, carbon steel and low alloy steel. Washington Alloy 190 is also used for overlaying on steel and for welding the clad side of joints in steel clad with a nickel-copper alloy.
APPLICATIONS
Washington Alloy 190 is a very popular electrode. Most common uses include electroplating and chemical pickling equipment, polyvinylchloride production plants, sea water desalination plants and in waste water treatment plants.
