It is superior to nickel rod in deposition, welding strength and joining between weld-molten iron and cast-iron weldment.

It can give cold-deposition to any large cast-iron weldment without preheating irrespective of seasons and makes it possible to process shut with machine.

Its coating material is abundant in the country and its core wire is made of ordinary steel. So it can be mass-produced without using nickel.

The newly developed welding rod is available for all sorts of cast-iron weldments.
