ENi-CI Cast Iron Welding Electrode
ENi-CI Cast Iron Welding Electrode Introduction
AWS ENi-CI is a covered welding electrode with pure nickel core and graphitic coating for cast iron. The weld seam metal has excellent machinability and cracks resistibility. Both AC and DC can be applied.
A nickel-cored electrode designed to weld normal grades cast irons. The weld metal is soft and easily machinable, deposition is performed or slightly preheated material. It is suitable for joining cast irons for the rectification of casting and repairing of broken parts.
The ENi-CI electrode is designed for welding of gray iron castings to themselves, as well as joining them to mild steels or stainless steels. Preheat and interpass of 350ºF minimum are recommended during welding.
ERNi-CI Cast Iron Welding Electrode Application
AWS A5.15 ENi-CI cast iron welding electrode is used for repair welding thin pieces and processing surface of cast iron, as well as important gray cast iron pieces, such as engine gearbox, machining tools, guideway, etc.
1. Welding electrodes must be baked for 1 hour at the temperature of 150℃ before welding.
2. For cast iron parts bearing impact stress, it is not good to use it.
3. For welding detects of small and thin cast iron parts fabricated by low steel, welding electrodes needn’t be preheated; for general welded pieces, welding electrodes should be preheated to around 400℃, cool it after welding and the welding zone may be processed by cutting.
Packing: In cartons of 20kgs net each, consisting of 8boxes x 2. 5kgs for size 2. 5mm and 4boxes×5kgs for other sizes.
