I have had good luck with MG 289 , which is an all nickle rod,use about 1/3 less amperage than you would normally use on a mild steel wire, the puddle will be very fluid. - AC;DC+ Graphite basic coated. Royal Welding Wires Ltd. offers superior-quality mild steel welding electrodes for industrial and residential applications for customers around the world. After welding, let it cool down at a slow rate for a couple of hours to avoid hardening and strong contraction stress. In either case iron or steel it pays to peen the hell out of it between each pass.Each electrode company has their (fancy ) electrodes for iron or steel such as cromatron,certanium,MG,perma,ect.AND pre &post heat should be consitered depending on base material and size. . Cast Iron electrodes (E-CI) with about 2.0%C, provide a structure similar to that of gray cast iron: the weld metal is likely to harden unless proper provisions are put in place. Characteristics : Newton -CI NM is a medium heavy coated, graphite electrode for non-machinable weld on all types of cast irons weld metal is extremely tough, Pre heating is recommended between 300C to 800C depending upon the thickness of parent-metal. In this case, a minimum penetration type weld is obtained and by the proper technique penetration should be kept to a minimum.

Standard Specification for Cast Iron Soil Pipe and Fittings ASTM International / 01-Jan-2009 / 44 pages . I'm pessimistic you will get a good result. The most common type of steel is the low-carbon or mild steel. The result is complete metal fusion without the need for fluxes, fillers, gasses, or an external heat source. It deposits a machinable weld which bonds to cast iron in a smooth and flat. If its steel use the 8018, if its cast iron use the Nickel 99. Most 300 series stainless will crack at some point, due to the excess carbon in the cast iron. By Dave Date 11-09-2001 17:29. It contains only 0.05-0.30% carbon and is by far the easiest metal to weld. Friction welding provides a high-strength, cost-effective solution to join steel and cast iron components together. Offered electrodes are used for machinery construction, truck frames and . Nickel-55 cast iron welding rod can be used for welding of gray cast iron, cast iron to carbon steel, cast iron . You have to preheat cast steel if it is thicker than 0.75 (19mm), it has more than 0.40% carbon, or it is low-alloy steel. Preheat to 250 F (120 C) to prevent hydrogen in the weld. I am faced with the task of welding a ductile cast iron gear to a mild steel shaft. Flux-cored self-shielding electrode wires (E60T-7), operating with electrode negative (straight polarity), have also been used for certain cast iron to mild steel applications. If you weld cast iron to steel with an ESt rod or with common rods such as the E7018, E6013, or even worse the E6011, you will have a high risk of cracking. Nickel 99 (AWS specification & Classification: A5.15- ENi-CI) is a high nickel base cast iron rod. 4. E7081-1 with supplement designation is used for welding of low-temperature applications. The PDF has 8 sections: Electrodes for mild steel. Your first step before you start any welding will be to actually check the parts. . . Any signs of damage are a no-go.

Step 1 - Check the Parts Thoroughly. Welding Cast Iron Electrodes; Creep Resistant Electrode; Welding Wire; Cast Iron Electrodes; . When done ,leave casting to cool in place (let the fire burn out). - Mild Steel General Purpose JACKSUN 5 - E 6011 JACKSUN 5 - E 6013 . The difference between cast iron and steel is the carbon content in each metal. Specification: AWS A/ SFA- 5.1 E 6013; IS 814- ERR 4211 ; . If performance is the prime thing, I've had great success with Aluminum Bronze A-2. way. ix AWS A5.15:1990 (R2016) Foreword This foreword is not part of AWS A5.15:1990 (R2016). The first specification for electrodes and rods for welding cast iron was published more than thirty years ago as a joint If that's not possible, brazing is a great solution. Since the electrode operates on low voltage and current, the heat input to the base metal is minimum. Ferro-Nickel alloy. Technical Detail Product Name Classification Mechanical Properties Of Weld Metal (Typical) Unique Feature(All Vaccum Packed) TDS AWS/SFA Yield Strength N/mm2 Tensile Strength N/mm2(MIN) Elongation 4D(%) Impact (J) Welding Conditions MACHINABLE CAST IRON WELDING ELECTRODES (HIGH NICKEL) 1 GM CAST 2 (55) E NiFe-CI 400 500 15 (2 in.)

The solid-state process requires minimal joint preparation and eliminates the possibility of porosity or slag inclusion . Cast iron is pretty easy to cut (although it is dirty), so there's often a way to drill and tap a hole for a bolt or drill a hole for a pin of some sort. After about 45 min.- 1 hour the casting should be warm enough to weld. On the other hand, cast iron contains more silicon and impurities compared to steel which ends up affecting such things as shrinkage rate, melting point .
