Cast iron welding is a necessary skill. Let’s say that the exhaust manifold on your Caterpillar digger cracks on a job site and you need to repair it. What should you do? Well, historically, the most reliable method has been to apply a special heating and cooling approach. You would remove the cast iron part, … Continued
Due to the temperamental nature of all cast iron types, there’s a common—as well as unfortunate—misconception that it’s nearly impossible to create a quality weld using cast iron. Several welders have been misinformed regarding the possibilities found in cast iron when it’s handled properly. It isn’t uncommon for the professionals here at Muggy Weld to … Continued
75 is a non-conductive nickel iron welding rod formulated to join dirty and contaminated cast irons. This universal electrode can be used to weld a wide variety of malleable, ductile, and nodular cast irons. In addition, it is ideally suited for the repair of defective or cracked malleable iron castings.
Ductile cast iron is a cast iron that is lighter than steel, corrosion, wear and impact resistant, high strength, and durable. Whereas brittle gray cast iron is used in shrink-free parts such as engine blocks and exhaust manifolds, ductile is used extensively in industries where tensile strength is vital, such as ductile iron pipes for water or sewer lines, oil-well pumps, agricultural tractors, truck axles, hydrostatic barrels, machine tooling, piano harps, suspension system parts, wheel hubs, high-pressure valves, steering knuckles, and spindle supports.
Malleable cast iron is similar to gray and ductile cast irons, but has the unique properties of being bendable and flexible without cracking. It has higher elongation properties than ductile cast iron, is stronger and more impact resistant than gray or ductile cast iron, and has high shock absorption and abrasion resistance. These qualities are useful in heavy duty applications such as marine equipment, railroad equipment, farm equipment, crankshafts, pipe fittings, compressor hubs, mining hardware, flanges, machine parts, universal joints, electrical fittings, hand tools, washers, brackets, fence fittings, power line hardware, and connecting rods.
Key Features:
Note: Begin by beveling the joint. Drill holes 1/2 inch from each end of the crack to prevent further cracking while welding. Tack weld to retain alignment. Use AC or DC reverse polarity, electrode positive. Maintain a short arc and make short passes and peen each pass promptly to chip off slag before cooling. Continue back whipping and overlapping until all deposits are connected. Cool naturally.
One thing that’s just as important as knowing how to weld is also knowing how to follow proper safety protocols. While a rewarding skill to have, welding can be incredibly dangerous if not done right. It’s for this reason that you should thoroughly familiarize yourself with proper safety rules before you begin any actual metalworking. We’ve created … Continued
72 burnt cast iron welding rod is a nickel free electrode which penetrates deep to seal in porosity generating contaminants prior to finish the weld with 77 cast iron electrode.
Cast iron is frequently used in industrial applications due to its low melting point, ability to withstand high temperatures, and durability. However, cast iron also tends to be brittle and can be exceedingly dirty, burnt, or heat affected–especially in maintenance industry welding applications. While 77 electrode has controlled penetration, which is ideal for non-cracking and machinability, it may not be able to bond to burnt or heat affected cast iron parts–72 should be used for these applications. With its high penetration, 72 can anchor deep into the subsurface of dirty cast iron, sealing in contaminates prior to finish welding with 77. 72 is used for a cladding operation, then the weld is completed with 77.
Key Features:
Note: DC Reverse (+), AC For best results clean and bevel the cast iron before welding. Remove all surface oil and grease along with rust, paint, etc. A bright shiny surface by grinding or sanding disk is optimal for the best penetration. Use stringer or moderate weave technique. When cladding, cover the entire base surface prior to finish welding. Not recommended for cast iron cookware.
