Nickle Alloy Welding Electrode E BK 92
Nickle Based Welding Electrode E BK 92 For DC+ SMAW stock electrode. 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 alkali’s.
Applications
BK 92 is developed for welding and cladding Nickel 200 and Ni
1736: EL-NiTi3
ckel 201. This alloy is also suited for surfacing of steel. Dissimilar welding applications of filler metal NiTi 3 include joining Nickel 200 and 201 to stainless steels, copper-nickel alloys, and Monel alloys. It is also used for joining Monel alloys and coppernickel alloys to carbon steels, and for joining copper-nickel alloys to Inconel en Incoloy alloys.
