Welding difficulties

When welding copper-nickel alloys, it is possible to oxidize the weld metal and dissolve hydrogen in it, which leads to the appearance of pores and increases the tendency to brittleness. The mechanism of formation of these defects is similar to that observed in the welding of copper. The nickel NiO that is formed has a melting point one and a half times higher than the melting point of the base material, and since NiO is still poorly discharged into the slag, it remains in the seam, impairing its quality.

Welding technology

Preferably, welding with a non-consumable electrode, since in this case there is less evaporation of zinc, tin and other elements. Preheating for copper alloys is required for thicknesses exceeding 12 mm. Gas welding is used in a limited way to obtain compounds of nickel and nickel-copper alloys. In acetylene-oxygen welding, a minimum flame is necessary, since an excess of oxygen or an excess of acetylene causes porosity, brittleness of the seam. For welding nickel, a filler wire with the same chemical composition as the base metal or with a small amount of manganese, magnesium, silicon and titanium is used.
