Acor Cu Ni
Copper nickel basic coated electrode
Description & applications
Basic coated copper nickel electrode for joining CuNi-alloys with up to 30%Ni and for surfacing the final layer on CuNi70/30 clad steel.
The weld metal is resistant against seawater. The electrode can be welded in all positions except vertical down, the slag is easy to remove and the weld beads are regular.
Main applications: In ship building, oil refineries, and desalination plants.
