Welding nickel alloys and dissimilar metals

Special high nickel base electrode for crack-free, welding of Inconel®, Incoloy®, Nimonic®, Monel® and Hastelloy® alloys, as well as high alloyed stainless steel, heat resistant steel and ferritic steel. The alloy is also used for making dissimilar welds between nickel alloys and steel, stainless steel and copper alloys and between steel and

copper alloys. The excellent mechanical characteristics at low temperatures make the alloy suitable for welding nickel-steels (9%Ni) for use at subzero temperatures (down to -196 °C. Deposits have superior corrosion resistance and are resistant to temperatures up to 1100 °C in sulphur free atmospheres. Excellent welding properties: a stable arc even at low amperage, very easy slag removal and excellent weldability on alternating current.

Specifications & Usage


Furnaces and heat resistant parts, where thermal shocks occur, installations for liquefied gas.

Joining stainless to mild steel, welding crack sensitive steel types even with heavy sections.

Cushion layers for hard facings on problem steels.


Clean the pieces thoroughly, remove oil and grease.

Use stringer beads (do not weave).

The electrodes should be used dry.
