Ni-Cu Welding Electrodel
MONEL Welding Electrode 190 is used for shielded-metal-arc welding of MONEL alloys 400, R-405, and K-500. It is also used for surfacing of steel. The weld metal is resistant to corrosion by sea water, salts, and reducing acids. The electrode is capable of producing weld deposits that meet stringent radiographic requirements. Although the electrode produces sound joints in MONEL alloy K-500, the weld metal has lower strength since, unlike the base metal, it is not age hardenable. Dissimilar-welding applications for MONEL Welding Electrode 190 include joints between MONEL nickel-copper alloys and carbon steel, low-alloy carbon steel, copper, and copper-nickel alloys.
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.
