ERNiFe-CI Nickel Alloy Welding Wire Tig Filler Rod Mig and Tig Welding Rods

Short Description:

ERNiFe-CI is used for welding of cast iron. This filler metal is extensively employed to overlay the cast iron rolls. It is also used to repair the castings. A preheat and interpass temperature of 175ºC (350ºF) minimum is recommended during welding, without which the weld and heat affected zones could develop cracks.

ERNiFe-CI is used for welding of cast iron. This filler metal is extensively employed to overlay the cast iron rolls. It is also used to repair the castings. A preheat and interpass temperature of 175ºC (350ºF) minimum is recommended during welding, without which the weld and heat affected zones could develop cracks.

Ni 55 (AWS class not specified) is a nominally 55% Nickel wire. The lower Nickel content makes this alloy more economical than Ni 99. Weld deposits are usually machine-able, but under conditions of high admixture, the welds can become hard and difficult to machine. It is often used for repairing castings with heavy or thick sections. As compared to Ni 99, welds made with 55 Ni are stronger and more ductile, and more tolerant of phosphorous in the casting. It also has a lower coefficient of expansion than Ni 99, resulting in fewer fusion line cracks.
