How Do You Weld Copper-Nickel?
Copper-nickel alloy provides excellent resistance to corrosion and has been used to make boat hulls for over 50 years and is commonly used in many marine applications. Since it is a malleable alloy, it can easily be repaired with welding if the need arises. You can attach two pieces of alloy together or seal a crack with a MIG welder. MIG welding copper-nickel is fast and controllable when repairing copper-nickel alloy. Does this Spark an idea?

How to Weld Copper Nickel
-
1
Prepare the surface of the welding area by cleaning with a stainless steel wire brush by removing paint, dirt and grime. Wipe clean with a shop towel.
-
2
Use clamps to hold the copper-nickel alloy in place if welding two separate pieces together. You may also tack weld them together by creating small welds in a few spots where the pieces mate.

3
Attach the alligator clip of the ground cable to the work area. Turn on the MIG welder and set to the desired amperage output.
-
4
Put on the welding helmet and insulated gloves. Create a weld pool with the torch. A weld pool is a puddle of melted metal that will form from the heat of the torch.
-
5
Allow the wire to stick out at least 1/8 inch from the wire contact tube when welding. Hold the contact tube in the direction of travel. Drag the weld pool along the length of the copper-nickel until the weld is complete.
-
6
Allow the copper-nickel to cool. Use the stainless steel wire brush to remove rough edges. Wipe away weld splatter with a shop towel.
