My father worked for Ingalls then became a machinist for Calumet and Hecla Wolverine division of Copper tubing works.

MG makes the best contaminated cast iron rod I have ever used. I repaired cast iron pouring cups on molds in an aluminum foundry for years using their rods. The cast iron cups were sprayed with a non stick coating several times a day. You can t get any more contaminated than that. Sometimes they were cracked sometimes they had holes and sometimes they were broken off. I drilled cracks and ground off the edges on the others to 45 degrees. Then preheated and made a pass on each side of the crack and peened each pass. Then joined and filled the gap peening each pass never allowing to cool. All passes are made at 30 to 40 amps. Then you wrap tightly in a welding blanket and allow to cool completely and repeen. Worked great on the nastiest cast iron I ve ever seen. The rods are high but worth the cost. The cups were in daily use and held up for years. The other rod companies I contacted said it couldn t be done but MG said they had just what I needed and if it didn t work they would send their field expert out to help solve the problem if it could be solved. It worked great with a few minutes on the phone with their expert for instruction. M G is an outstanding customer service based company with many problem solving rods.

Many interesting comments. When I learned to weld cast iron during my apprenticeship late 60S, we had cast iron welding filler rods. They were .25" square cross section and about 24" long. Used these with an oxy set and the filler "disappeared" into the work. You end up with an almost invisible weld that looked almost like the original! The cast iron filler rod became the workpiece, it merged before your eyes. No cracks, no joins just solid cast iron! Beautiful! It did require pre and post hearing to relieve stresses. Cast iron filler rods have not been available in Australia for MANY years. Regards Peter

I came from the old school of silicon bronze filler for cast iron. What a PITA. Even after stop drilling, v gouging, pre heat 500deg. in a heat treat oven and short stitch TIG welding and peening followed by post heating with natural cool down, the manifolds just like yours (small block Ford) still had the distinctive 'tinkling' sound of cracking at room temp. Arrgghh!!! Had to do that one all over again before success. There's an additional addendum to this story, maybe fodder for later??Then I discovered Eutectic's '680' filler. Considerable stretch when cooling, works on all ferrite materials, and beautiful easily controlled puddling. Worked even when you do not take all the time, precautions with a quick and dirty give a hoot attempt. Used to feel this would make a rookie look like a hero!!But this new Muggy filler is new to me.

​@@BrandonLund You're welcome. It's a very strong and resilient alloy, it has been designed in the end of the forties for welding turbine blades on the jet engines. So it's practically impervious to heat, thermal cycles, vibrations and corrosion. Besides it's very easy to use, needs lows amps, works AC and DC, giving beautiful welds with small inverters, and the "glass" pops alone. Another use I did was for welding galvanized tubing as the HAZ is pretty small and the welds need none grinding after. So no job after, just a local cold galva on less that one inch wide. That pays alone the price in professional use, cutting down the work.

A little informative side step from the main topic: Many people know to drill a hole in material to prevent further cracking, but never thought about why this works. It has to do with Pressure = Force / Area (P=F/A). When you drill a hole, that force is applied over the circumference of the entire hole you drilled instead of the end of the crack. The pressure is diminished by spreading the force over a greater area. Obviously, if the force is too great, and the hole too small, it can crack beyond the drill hole. Been there.

I even managed to grab it, but it rolled out of my hand and broke into 3 pieces - nowhere near the weld btw! Moral of the story was, sometimes cast becomes so brittle that it's a waste of time repairing it.

Hey brandon if your reading this to help with cast iron, place some scrap plate next to your crack and strike a very low setting arc on the plate and heat a low setting up then dip over to your crack, its alot more efficient then trying to start the arc on the cast iron if its stubborn, if that manifold is thick enough then need not to worry it just helps get a better temperature for your start.

Some twenty-odd years ago, my neighbor had an early '70s Ford pickup with a 460 and a HUGE crack (1/4"+) in the exhaust manifold. He asked if I could weld it, so we gave it a try. We used my wire-feed welder with ER70S-7 wire, and an acetylene torch with a rosebud tip. With it still on the truck, we heated the manifold up to a dull/medium orange, then with the welder set at a low heat setting, proceeded to fill in the gaping maw that was the crack, until it was sealed. It still wasn't leaking when he sold the truck some 5-7 years later. I'm still amazed and impressed.

I also never use grinding wheel to prep weld area. I used dremmel bit. Does not smear metal molecules like a grinding wheel. Heat up before weld and cover or wrap to let weld cool slow as possible to room temperature. I used fire bricks when able to retain heat and a weld blanket if available. Problem was other workers would steal blanket. I preheated bricks in welding rod warmer that I used for 7018 rods to keep out moisture. Loved certanium. I to always drilled holes end if cracked area.

Brandon, I am a cast iron expert with 40 years experience. Almost all your information is spot on except one thing you NEVER use nickel rod on an exhaust manifold regardless of any claims to the contrary by the manufacturers of the rod. The reason is simple they get red hot during hard driving. If you don't believe me just run your car hard at night the look at the manifold, it will be glowing red. The expansion/contraction rate of nickel is much different than cast iron and it WILL eventually crack again. It's not a matter of whether it will crack but when. I've been shown nickel repaired manifolds that the owner claims are holding just fine but a close inspection will show a hairline crack along the edge of the weld EVERY time if it has been awhile since the repair. There is only one way to PROPERLY repair an exhaust manifold and that is by using the same material as a filler rod; in other words you MUST use a cast iron rod as a filler because it has the same expansion/contraction rate. They are available at some welding shops but can sometimes be hard to find because so few welders know how to use them and the ONLY way to use them is by gas welding with a high heat flux. The manifold must be clamped to a strong back to hold its flatness and even then it may have to be ground flat at a head shop. Preheating and post heating the entire manifold to the proper temperature is a must; generally to a blue/brown color but temp sticks are better at about 500 to 600 degrees and it must be buried in sand (preferably heated) for slow cooling or slowly cooled in an oven. It is well beyond the experience of even most experienced welders as it is like welding mud and it takes a LOT of practice to do properly. I would suggest you try it just for the experience. It is somewhat like regular gas welding but MUCH harder to do properly. Exhaust manifolds have gotten to be pretty cheap with many running just $50 to $100. And I can assure you I would charge more than that to properly repair a manifold but some are hard or impossible to find and that's when you find someone who can weld manifolds but you MUST insist it be done with cast iron rod. If they claim otherwise find a different welder. One note about using nickel rods. You are right about welding one inch at a time (depending on the thickness) and peening the weld after but a good rule of thumb is allow it to cool to the point where you can place your hand on it before welding the next inch. Cast iron welding takes time either by using nickel or cast iron rod. I watched my boss try to nickel weld a cast iron bell housing once and he tried to do a four inch weld all at once. Even with peening it kept cracking on him. I could not convince him how to do it properly so I walked away; he never did get it repaired and trashed it. He had decades of welding experience but no cast iron experience. Even welders with that much experience sometimes just don't know how to do cast iron.

If I were a customer with a cracked block, I would gladly pay a few hundred dollars or more to have my boat fixed Vs. buying a whole new motor. A lot of people are under the impression that cast iron cant be repaired. That is far from true. As long as they know it will never be as strong as the factory original and that there is a possibility that it could fail at some point down the road, everyone wins.

The undercut may be that you went a bit fast with your weld and didn't let the weld fill in. There is a tendency to run quick with cast iron because it doesnt like heat, but you still have to allow that weld rod fill in its own cut. Excellent video

jason bourne You are spot on when you say there is a tendency to run quick when welding cast. We all try to limit that heat input, and in an effort to do that, sometimes we go a bit too fast. Thank you for this great comment! Cheers brother!

I have a test piece of cast iron that was stick welded with a pure nickel electrode sat in my wood stove, it has gone through hundreds of heating and cooling cycles and not cracked. I preheat to 300 c, stitch weld, then leave to cool overnight in a bucket of dry sand.

I watched because we share the same last name. Probably not related. I am adopted anyway. Years ago the cast iron hitch for our disk (farm tillage thing) broke and Dad started hunting for a new used disk because in the 70's there weren't many options. Our local blacksmith didn't want to tackle it. My HS shop instructor suggested cast iron rods which were apparently new. I was not an accomplished welder by any sense of the word. I gave it the can do anything if you try attitude and we used that disk for several years later. Oliver brand. I got really lucky. Years later I became a certified weld inspector at a major defence contractor. Was just one of those merit badges that I rarely needed. But, a nice tool to have in the box. Hole drilling to stop the crack is a very sound metallurgical method.

Great name Larry. Its actually a made up name my great grandfather came up with when he immigrated to the United States from Sweeden. His last name prior to the name change was Mattson, so for that reason I'm not related to many lunds :). Cast iron rods are awesome! You can still get them but its becoming a lost art.

As at least one other guy has said this is an exhaust manifold for a GM LS engine and they are likely cast steel rather than cast iron. And they are very popular for DIY turbo manifold setups. I am running a set of these manifolds on my turbo 6.0 and I welded/modified them extensively using a MIG welder and no preheat or other fancy gimmickery.

If they are iron, they can be MIG welded with a little patience and no cracks. Tons of people on LS1tech doing it and I've done it. Rockin' em on the turbo 6.0. If it is iron like you guys say, it's a way better iron than you'd find on a manifold from a small block in the 70s.

The welds in this video do look very nice. Even the 72 rod seemed to weld nice. I've seen other muggy weld videos that didn't have such pretty welds. They actually looked pretty bad. Unfortunately I did not have a positive experience in using this rod. I recently tried the 77 rods to weld a cast iron hydraulic fitting to a steel JIC fitting. This should have been the perfect solution since it is advertised to be able to weld steel to cast iron with little or no porosity. The surfaces were carefully prepared/beveled on a lathe and cleaned very well to all shiny metal. The 77 rod would not hold an arc at 100 amps and would barely weld at 115 amps which is higher than the max recommended heat. The beads seemed to burn in if I could get it to hold the arc but I later found out the welds did not bond that well. The 1/8 rod is supposed to hold an arc from 60 to 110 amps. This rod is advertised to have no porosity, however after cleaning up the weld on the lathe, I found 6 pin holes that caused leaks. I attempted to grind them out and re-weld them, but more leaks appeared. After grinding out the pin holes, I found the penetration was much less than acceptable. This rod is also supposed to be easily machined. I did machine the weld, but I broke 4 carbide bits in the process. Realizing this rod was not meeting the manufacturer's claims for my application, I went old school and brazed it and then machined the surface again and solved the problems. I have no leaks and a professional looking fitting. Sometimes the old proven ways are the best. At $12 per rod shipped, I expected superior results. Needless to say, I was completely disappointed with the performance of this rod. Some people may have good success with this rod, but I found out the hard way, at least in my case it did not perform and failed on all points. So at best, I'd say as an experienced welder, It might weld well in some cases, but not so good in other cases for no apparent reason. I'll stick with tried and true from now on. I need something I can count on at a fair price.

@BrandonLund

I'm sorry to hear that your experience was less than desirable. I assume you were running DCEP? I ran both of these these rods at the lower end of the spectrum but I think my unit might run a couple amps hot but I have yet to confirm that. I did not experience any problems keeping them lit and the re strikes were crisp. I spun the rod between passes on a file as I mentioned in the video just to keep the electrode exposed. The 72 rod went in nice for me. It felt like 6010/6011 while the 77 rod seemed a little more forgiving and flowed similar to a 7018.. Again, sorry to hear you had a bad experience. Welding cast is stressful enough as it is :) Thanks for watching!

@keithmray

I was running an AC box I've had for decades. I didn't run the 72 rod because that was intended for contaminated metal and it mentioned that the 72 rod would be more porous. My casting was very clean and perfectly prepped. It did look like it flowed in nicely for you. I believe if I'd turned up the heat to an even hotter setting, It would have welded better, but that would be going against what you're trying to do working with cast iron. My observation is, it's not consistent from one situation to another. I probably could have experimented and gotten decent work out of it, but I couldn't risk destroying a casting that coudln't be replaced. I needed it to work according to the specifications and manufacturer's recommendations. That just isn't how it worked out.

That Manifold appears to be from a V8 Buick .

I have welded many Manifolds like this and not had issues. A neat trick if there is a spring works close by is ask if you can place the manifold in their Oven for a couple of hours and then into the hot sand pit if they use one to cools slowly :)

I can vouch for the efficacy of Muggy welding rods. They flow and wet in like butter. They're my go-to rod on cast iron. You can also knock the flux off and TIG with them. I keep a selection of these rods on hand for the occasional cast iron job and they always work well.

Looks like a LS exhaust manifold

I weld cast iron with a plasma welder using plain mild steel rods and a small amount of preheat. The weld area becomes a combination of the cast iron and mild steel as the weld pool forms a medium carbon alloy. At the same time I never clean the weld area as the plasma welder cremates any rust or dirt into a powder and it blows off with the plasma flame and leaves a clean metal area. I've welded many cast iron frames for garden furniture that have cracked over time. Best weld repairs were on cast iron drilling machine tables that people have drilled into. The plasma welder is a Multiplaz 3500.

I wonder about the cause of an actual crack. It could be about load stress. You are one of the few with confidence in a cast iron repair. Farm equipment is the extent of my welding and all I have is an ancient AC rig. Glad to know these rods will work for me. Thanks for a great video!
