Product Description
Introduction:
AWS ENiCu-B is a kind of cast iron electrode with Ni-Cu alloy (Monel) core wire and strong reducibility graphite type coating.Both the welding performance and the machinability are quite similar with those of AWS ENi-C1.However,dueto the higher shrinkage rate, the crack-resistance is worse, The welded joint has lower strength,so it is not suitablefor welding force-bearing parts. It can be used for welding gray cast iron under normal temperature or preheated a little (to about 300ºC).AC/DC.
Application:
Used for repair welding on gray cast iron pieces not requiring strength too much.
Instruction:
1.The electrodes must be baked under about 150ºC for an hour before welding.
2.When welding,stringer bead is suitable in the manipulation of electrodes. Every time, the weld length is suitable when lower than 50mm. The welded places should be hammered lightly immediately after welding so as to eliminate the stress in the welded areas and avoid cracks.
