AWS A5.15 / ASME SFA5.15 ENi-CI
JIS Z3252 DFCNi

EN ISO 1071 - E C Ni-CI 1

Notes on Usage

Welding Positions:

① Chip off base metal completely at the repairing part.
② There is a possibility that cracks spreads or makes holes at both ends of repairing part.
③ Keep the weld metal length less than 50mm(2 inch) to disperse welding heat. Adopt back stepping stone or symmetry method by turns.
④ Hot peen in every pass.

⑤ The preheat temperatures vary in accordance with the size, kind and shape of the base metal.150℃(302℉) is appropriate in general.

Applications

AWS A5.15 / ASME SFA5.15 ENi-CI can be used for repairing cast iron and joining of various kinds of cast iron products such as cylinder covers, motor beds, casings and gears. Repairing of meehanite, alloy and malleable cast iron.

Characteristics on Usage

AWS A5.15 / ASME SFA5.15 ENi-CI is a graphite type coated electrode, depositing nickel weld metal. Hardening of heat
affected zone is small and machining of the welds is comparatively easy. Therefore it is suitable for welding alloy cast iron of poor weldability, malleable cast iron and hydraulically pressured partsas well as common cast iron. AWS A5.15 / ASME SFA5.15 ENi-CI
