Description
CARBO DURIT Ni E – 6 mm
CARBO DURITNi E is a specialized electrode designed for manual arc welding. The alloy, with its low melting point ranging between 900 and 1000°C, flows exceptionally well. The nickel-based matrix alloy offers superior resistance against acids and other corrosive agents. This electrode is unique in its ability to produce a smooth, clean surface. It’s a tubular rod that contains fused tungsten carbides embedded in a nickel base matrix alloy.
- Standards: DIN 8555 G 21-GF-UM-50-CG, DIN EN 14700 E Ni20
- Welding positions: PA, PB
- Flux-cored wire equivalent: CARBO F-DURIT Ni
Characteristics
- CARBO DURIT Ni E is “unique” in that it produces a smooth, clean surface.
- CARBO DURIT Ni E is a tubular rod containing fused tungsten carbides in a nickel base matrix alloy.
- The weld metal is composed of 60 to 65 % fused tungsten carbides which are embedded in a matrix alloy containing 35 to 40 % NiSiB.
- CARBO DURIT Ni A is used for applications which are subject to extremely heavy abrasive wear and corrosive media at the same time.
Typical applications
- Hardfacing equipment parts made of ferritic and austenitic steels.
- Mixer blades, milling plates, conveyor worms, stabilizer blades, slurry pump valves
- Moulding sand preparation plants
- Corrosion resistant welded coatings on parts which are subject to strong abrasive wear, e.g. in the chemical industry and the food industry.
Recommendations for best welding results
- Thoroughly clean the welding zone. It should be exempt from grease, scale, corrosion, and similar contamination.
- Preheat the work piece to 300 – 500 deg C.
- During the welding process the local base material temperature has to be increased to 650 degC, however, overheating should be avoided.
