Description
Welding rod/wire electrode made of nickel with particularly low carbon content for TIG or MIG welding of pure nickel for operating temperatures up to +450°C. Cold-tough up to -196°C.
Most important applications
Nickel, low alloyed nickel (Ni-semi-INi-casting), e.g. LC - Ni 99,6 (2.4061), NiMn 5 (2.4116), G - Ni 95 (2.4170) as well as joints with steel, cast steel, copper;
Plating and buffer layers

Special notes
Cleanliness of the workpiece in the weld area is a prerequisite for a crack-free joint. Bottom seam protection is required for thin sheets and root welds. For V- and X-welds the opening angle should be at least 70°.
TIG - Welding rod should always be guided in the protective gas area.
MIG - wire electrode should preferably be welded with pulsed arc. At high welding speeds work with a gas shield following the torch (argon shower).
