Filler Metal Alloy 61 is used for submerged-arc welding (SAW) of Nickel 200® and 201. It is also used for surfacing and strip cladding of steel. Suitable submerged arc flux, should be used with the submerged-arc process. The reaction of titanium with carbon maintains a low level of free carbon and enables the filler metal to be used with Nickel 201. The weld metal has good corrosion resistance, particularly in alkalies.
Dissimilar-welding applications for Nickel Filler Metal 61 include joining Nickel 200 and 201 to stainless steels, carbon steels, INCONEL® alloys, INCOLOY® alloys, copper-nickel alloys, and MONEL® alloys. It is also used for joining MONEL® alloys and copper-nickel alloys to carbon steels, and for joining copper-nickel alloys to INCONEL® and INCOLOY® alloys.
