Technical data
EN ISO 18274: S Ni 2061 (NiTi3)
AWS A5.14: ERNi-1
Material no.: 2.4155

Applications
For alloy-like joint welding of
2.4056 - Ni 99.6 Si
2.4062 - Ni 99.4 Fe
2.4066 - Ni 99.2
as well as for mixed joints with unalloyed and low-alloyed
steels, e.g:
P 235 GH, P 265 GH, 17 Mn 4, S 255 N, S 355 N.
Also for non-alloy joint and build-up welding (cast iron cold welding) of cast iron with lamellar or spheroidal graphite, austenitic cast iron, white and black malleable cast iron as well as joint welding with steel or cast steel. Also for production welding.

Typical applications are
Pipes, fittings, containers, apparatus, heating coils, evaporation elements, pumps, valve parts, mixer parts, heat exchangers as well as pressing and drawing tools, large valves and gate valves, rolling mill cylinders and cast iron sealing rings.

Processing instructions
Clean welding areas. Adjust the heat input during welding to the component, its material and dimensions. Weld workpieces with low energy in line bead technique. Limit the interpass temperature to 150 °C. Ensure a continuous supply of filler material.
Form sufficiently for root welds. Use wire brushes made of austenitic CrNi steels.
The following also applies when welding cast iron:
Remove cracked and otherwise damaged material as well as the casting skin. Generally weld without preheating. Weld workpieces subject to shrinkage, especially those made of laminar cast iron, with short beads (1-3 cm long). Immediately after welding, hammer off the weld beads when red hot. Allow the workpieces to cool slowly in the oven or under insulating materials.
