Application

Repair welding of defects in gray cast iron components.

Characteristics

JL-Z208 is a cast iron welding rod with a low-carbon steel core and a strongly graphitized flux coating. It can be used with both AC and DC power sources and is cost-effective. The weld seam can transform into gray cast iron when cooled slowly, but it has relatively poor crack resistance.

Deposited metal chemical composition:%

Reference welding parameter: (AC、DC+)

Note

The welding rod must be baked at 250±10°C for 1-2 hours before use.

For small thin-walled castings with defects in areas of insufficient rigidity, preheating may not be required for welding repairs, whereas general weldments must be preheated to 400±10°C. Post-weld slow cooling with insulation should be maintained, after which the repaired area may potentially be machinable.

This welding rod is not suitable for important casting structures subjected to stress and impact.
