Copper-Nickel: Welding and joining plate, sheet and pipe

While copper and nickel are mutually soluble with each other as shown in Figure 1, a number of other elements are not soluble in the Cu-Ni alloy and if present may cause cracking in the heat affected zone (HAZ) or weld metal.Lead, sulfur and phosphorus are particularly detrimental and may cause intergranular hot cracking in highly restraint joints.
