| Description
and Applications |
| Nickeltech
is a nickel cored coated electrode for without preheating repair |
| welding
of all current cast iron qualities, nodular cast iron and all kind
of |
| malleable
cast irons. It is recommended also for joining these cast irons to |
| steel,
to stainless steels and to copper alloys. |
| Distinguished
by its outstanding welding characteristics such as good |
| wetting
ability of the molten metal. Before welding dirt, paint, oil and |
| grease
must be removed from the surface of the material to be welded |
| over
sufficient with. Small electrode diameters, low amperages, short arc, |
| short
runs less than 10 times electrode diameter are recommended to |
| avoid
overheating. After the weld metal deposition slag must be remove |
| immediately
and the bead must be penned to release the welding stresses. |
| Preheating
to 100-200ºC is recommended for thick walled components. |
