61
AWS A5.7 ERNi-1
ASME SFA 5.14 ERNi-1
61 is a high nickel filler metal used for MIG, TIG or plasma arc welding of
high nickel base 200 or low carbon nickel 201 to themselves or to each other. 61 is also used for joining nickel 200 and 201 to dissimilar metals such as carbon steel, stainless steel, Inconel® and Incoloy® alloys, copper-nickel alloys and Monel® alloys. Excellent for overlaying
on steel and for welding cast iron. Titanium content in the wire controls weld metal porosity.
