Cast Iron Electrode Carver - 9750
PROCEDUREAll rust, scale and oil should be removed from the surface to be welded. Preheat casting to 250C and maintain interpass temperature. Maintain a short arc and use either the stringer bead or slight weaving technique. Skip weld in order to dissipate the heat as evenly as possible into the work piece. Peen rapidly to help relieve stresses. Always back-step the crater before breaking the arc. Clean off slag between passes. Cover the finished unit after welding in order to retard the cooling rate.
APPLICATIONSUse CARVER 9750 when high strength crack-free welds are required on all cast iron maintenance applications; including motor housings, gears, sprockets, ladles, flaska and trasmission housings, Excellent for building up shy areas and filling holes in castings. Use for all repair and joining welds on gray, malleable, ductile and nodular cast iron and their joining to steel alloys.
FEATURESCARVER 9750 is for the repair and joining of heavy sections of cast iron. The high carbon in CARVER 9750 promotes the formation of graphite in the weld metal, thereby reducing shrinkage stresses and the possibility of heat affected zone cracking. CARVER 9750 weld deposits are machinable. Designed specifically for on-the-job repairs of cast iron, which eleminates the necessity of dismantling equipment. While pre-heating is recommended, the electrode may be used without pre-heating or post-heating in many instances.TECHNICAL DATAAlloy Type : Ni, Fe AlloyTensile Strength : 430 N/mm2Machinability : GoodHardness : Rockwell C 21-26RECOMMENDED CURRENT RANGESIZE (mm) 3.15 4.00 5.00AMPS 90-110 100-130 140-170
