Electrode for joining dissimilar metals with highest crack resistance

Special electrode with high nickel content for joining unalloyed and alloyed steel, stainless steel and heat resistant steel, nickel and nickel alloys, copper and copper alloys.

Also suitable for dissimilar welding of these metals. The deposit has a very high ductility, is ferrite free, corrosion resistant and heat resistant up to high temperatures.

Excellent weldability on alternating current.

Specifications & Usage


Joining dissimilar metals, especially for high thicknesses and rigid joints.

Welding of cryogenic steels: vessels and pipes for liquefied gases.

Intermediate layer in copper-steel joints.

Welding of crack sensitive steel types: roller guides of cement kilns, hydraulic cylinders.


Clean and degrease the work piece.

Weld with a short arc, the electrode almost vertical to the work piece.

Crack sensitive steels should be preheated depending on the composition and the dimensions. Normally 100 to 250 °C (210-480 °F) will be sufficient.

Always use dry electrodes.
