Application

Suitable for repairing thin cast iron parts and machined surfaces, such as cylinder heads, engine mounts, gearboxes, and important gray cast iron components like machine tool guide rails.

Characteristics

JL-Z308 is nickel core graphite-coated cast iron electrode. The coating appears black with a slight reddish hue, suitable for both AC and DC applications, featuring stable arc performance, fine droplet transfer, and uniform slag coverage.

Deposited metal chemical composition:%

Reference welding parameter:(AC、DC+）

Note

The welding rod does not require pre-baking before welding. In cases of poor packaging or moisture absorption, it can be baked at 80-120°C for 1-1.5 hours.

Stress in the weld repair zone can be relieved by hammering the weld to avoid cracks.

To minimize the infiltration of impurity elements from the base metal into the weld, reduce the width of the chilled zone, and improve crack resistance and machinability, small currents should be used as much as possible for cold welding of cast iron.
