MONEL ® Welding Electrode 187
Roshako offers MONEL Welding Electrode 187, specifically designed for shielded-metal-arc welding of wrought or cast 70/30, 80/20, and 90/10 copper-nickel alloys. Known for its exceptional resistance to fouling and corrosion in seawater, this electrode is widely used in marine and desalination applications. It is also suitable for dissimilar welding, including joints between copper-nickel alloys and MONEL alloy 400 or Nickel 200.
With excellent operability for groove and fillet welding in the downhand position, the smaller diameter electrodes are ideal for all-position welding. Powered by direct current, electrode positive (DCEP), Roshako’s MONEL 187 welding electrode ensures high-quality, durable welds for industrial applications across UAE, Dubai, Abu Dhabi, and the GCC region.
