Technical data
DIN EN ISO 1071: E C Ni-CI 1
AWS A5.15: ENi-Cl
Applications
For non-alloy joint and build-up welding (cast iron cold welding) of cast iron materials such as malleable cast iron, cast iron with lamellar or spheroidal graphite and for repairing oil-soaked cast iron materials.
Typical application examples are
Cylinder blocks and heads, oil and water pumps, oil pans, slide and gearbox housings, eccentric disks, base plates of loom shutters, beater hearts, rollers, pistons, cylinders and sliding surfaces.
Processing instructions
Remove cracked and otherwise damaged material as well as the casting skin. Thermally work out cracks and drill off crack ends. Clean welding areas. If possible and if conditions permit, preheat the component to 150 °C to a maximum of 300 °C. Weld as cold as possible (≤ 300 °C) with short stitch beads. Weld workpieces subject to shrinkage with short beads (1 - 3 cm long). Immediately after welding, hammer off the weld beads when red hot.
Welding positions: all, except PG (f)
Type of current: = (-- ) or ~
