“Bimetal“ electrode for cast iron welding
Description & applications
Graphite-basic coating and «Bimetal» core wire with high electrical conductivity. The «Bimetal» core wire authorize very important fusion speeds with direct current as well as alternative current without any overheating risks of the electrode (phenomenon often notice with conventional Ferro-Nickel).
For repair and construction welding on all cast iron types and dissimilar joints between cast iron and steels.
Grey cast iron, malleable, nodular:

Welding Instructions
Alternative current favours the welding in all positions. The polarity + is essentially reserved when an important deposit speed on large chamfers is searched, or on areas with difficult access (reduced visibility of the joint) - For same applications, it’s recommended to depose short beads followed by immediate hammering to release stress.
