MONEL Welding Electrode 187 

 

MONEL Welding Electrode 187 is used for shield-metal-arc welding of wrought or cast 70/30, 80/20, and 90/10 copper-nickel alloys. Like the baase metals with which ti is used, the weld metal resists fouling and corrosion in sea water and is useful for many marine and desalination applications. Dissimilar joints welded with the electrode include those between copper-nickel alloys and MONEL alloy 400 or Nickel 200.

 

The eletrodes 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.
