Abracast 11 S
Bimetal” electrode for welding cast iron
Product description
Graphite-base coated electrode with ‘Bimetal’ steel core for high thermal and electrical conductivity.
The ‘Bimetal’ core allows very high melting speeds in both DC and AC without the risk of electrode overheating (a phenomenon commonly observed with conventional ‘Ferro-Nickel’). Suitable for assembly and repair of all types of highly-stressed cast iron and for all heterogeneous cast iron/steel assemblies, as well as for cast iron contaminated by paint, oxidation or oil. Casting defects, machine tool frames, gearboxes, cast-iron piping, etc.

Alternating current favors welding in all positions. The + polarity is mainly used when high deposition speed is required on large chamfers, or for all hard-to-reach areas (reduced joint visibility). For all flanged parts, we recommend depositing short beads of approx. 3 cm and hammering them in immediately to release residual stresses as far as possible.
