General Description
Electrode for welding of corrosion resistant NiCu-alloys, and for welding of Cu-alloys with Ni and Ni-alloys, and also for anti corrosion deposit on mild and low alloyed construction steel. Deposit metal resistant against cracks, it is ductile metal and correspond to the most strict requirement for corrosion resistance in sea water, acid and alkaline. Electrode applicable for welding of corrosion resistant steel like “Monel” on production of petrol and ammonium sulfate, and also in energetic objects.
