Re: [MW:22688] Copper alloy electrodes

Hi,

There are special consumables made for 90/10. You can contact manufactures like bohler (UTP), FSH & special metals. 

Consumables of type ELCuNi10Mn

Will give you 90/10 composition.

Dear Yogesh Pawar,

Kindly see the attached details of options available, to weld MONEL (Cu-Ni)

These are the products of Special Metals-USA.

Also, enclosed is 'Selector Chart' for  Nickel- based Alloys.

In case, you need welding consumables for other Copper-based alloys, then

AMPCO - USA products are available.

Best Regards

Nearest available electrode could be monel type with 70 Cu - 30 Ni.

GMAW followed by SMAW is suitable GTAW.

ECuNi- Coated Electrode

Copper-nickel alloys and selected bronzes to themselves and to Alloy

400 or Alloy 200

Electrodes of the Copper-nickel classification are used for shielded metal

arc welding or wrought or cast 70/30, 80/20 and 90/10 copper-nickel alloys

to themselves or to each other. They also are used for welding the clad side

of copper-nickel clad steel. Preheating is generally not necessary.

 

ERCuNi - Filler wire.

Copper-nickel alloys and selected bronzes to themselves and to Alloy

400 or Alloy 200.

In Copper-nickel filler metals, the nickel addition strengthens the weld metal

and improves the corrosion resistance, particularly against salt water. The weld

metal has good hot and cold ductility. Copper-nickel filler metals are used for

welding most copper-nickel alloys. When using the GTAW or GMAW processes,

preheating is not required. Welding is done in all positions
