Stick Welding Cast Iron Repair with Muggy Weld

6899 ratings | 984713 views
Stick Welding Cast Iron Repair with Muggy Weld. Cast iron can be tricky to repair because it's prone to cracking. Follow along as I repair a broken cast iron exhaust manifold using Muggy Weld with no pre-heat. For this demonstration I used a 2 step process starting with an electrode that can withstand the dirtiest of cast irons followed by a cap that has excellent crack resistance properties. Although I believe a good pre-heat and a slow cool down will give you the best chance for success, i wanted to see how this rod would respond in a worst case scenario such as cold welding. It handled the thermal stresses excellent without any signs of cracking. This would be a huge bonus for parts too big to get a good pre-heat / cool down or for parts that are not cost effective to be removed. Hit the notifications! We are going to be doing some more experiments with these rods, including tig welding.

Always place manifold in a charcoal grille and allow to fully heat up. Then weld. Then place back in charcoal fire and allow fire to cool and go out naturally. Next day all is well. It won't ever re-crack.

Hey Brandon , I would like to try the Muggy weld 72 and 77 rods to see if they can build up erosion on a 180 ton Carrier chiller. The water box lid and flange are rusted out!! I like your videos and was able to fix my broken cast bench vise after watching you weld cast with your mig. Thank you , keep up the good work!!

Thanks for the video Brandon! I I recently graduated welding trade school and don’t have much field experience so I love these videos. I just have a question. You drilled the crack so it wouldn’t spread but wouldn’t the weld consume the entire crack melting and fusing the edges anyway? Would you be able to explain how the crack would still spread even after being consumed by the weld and how drilling it prevents that? Thank you!
Brandon Lund (4 days ago)
Good question Michael. You would think that the weld would consume the crack but I was taught that the radius from the hole is what terminates the crack and keeps it from spreading.

Hi Brandon, with muggy weld rod I would repair a cast iron boiler used to heat a house. The pressure regulation system on the boiler failed causing the pressure to rise and breaking a piece off the boiler. One particular section was shattered and will have to be replaced by welding in a piece of mild steel.🤞🤞🤞

Okay... If I had some muggyweld I would use it to repair a cast iron flange in place. It's not coming off the tractor where it's been for 52 years. I have some Craftsman 3/32 cast iron rods that run on ac or dc. They are older than you and the flux is coming off them. I really need a proper weld with less chance of blowing through or cracking the iron. I can weld it with a warmed up motor.
Brandon Lund (7 days ago)
Your in it David and those Muggy Weld rods would be perfect for that repair! Be sure to keep an eye on that video. As soon as it hits 1M I'm making the announcement. Good luck!
Daniele Silvaggi (7 days ago)
A couple years back I had my Chevy 383 stroker engine on my engine startup stand and I couldn't get it started so I had it in my garage and it was the coldest winter ever here in Windsor Ontario Canada and guess what? Yup the block cracked in 2 places. I could send you the pics. So I have been doing a lot of research into welding it and I have heard about Muggy Weld but have not bought it yet. I would love to try it so I can finally get my 1980 Camaro back up and running again. Thanks for the opportunity for getting some.
Brandon Lund (7 days ago)
Your in it Daniele! It's a shame that the stroker got cracked but the good news is that Muggy Weld is a perfect fix for that! Be sure to keep an eye on that video. As soon as it hits 1M I'm making the announcement. Good luck!

The place I served my time at would have put that in the oven for a few hours before welding and in some cases the rods were also put in the oven.

That's my preferred method Carl. I wanted to see how these rods worked in a worse case scenario (no preheat, no post heat and no insulated / controlled cool down. They passed brilliantly.

Welding galvanised steel can be a pain. Makes my friend sick cause he doesn't wear a resperator and the fumes make him sick
Robert Green (7 days ago)
+Brandon Lund yes I've heard milk helps. I arc welded today and my shirt wasnt buttoned up at the top. Now I am flash burnt there. Not bad but still I would rather not have it
Brandon Lund (7 days ago)
You got that right Robert. It's also called Metal Fume Fever. I've had it 2x. If your buddy refuses to wear a respirator, at least have him pound some milk right after welding. It lessens the symptoms. Some say it's a myth but it worked for me and others I know.
Robert Green (8 days ago)
+Brandon Lund not problem. It is better to be protected than being sick
Brandon Lund (8 days ago)
My apologies Robert, I must have stainless on the brain, I meant to say galvanized not stainless. Galvanized metal is toxic when grinding, heating and welding. You should still use PPE when welding cutting grinding but stainless is not toxic like galvanized.
Robert Green (8 days ago)
+Brandon Lund I didn't know about stainless, although I'm not a welder by trade, I've never don't tig welding just arc welding. But that is an important thing to know about stainless. Thanks 👍

Good video , Ive always had better luck with parts from an engine if they are heated up , baked prior to welding to remove soaked in oil . Especially diesels. Ive really come to enjoy tig welding most stuff. Great video though , I sure will give muggy weld a try next time I have some damaged cast iron.
Brandon Lund (13 days ago)
Thanks Mark! This was more of a test to see how these rods would respond using the cold method. As you pointed out, I would also go with a preheat and post heat cooldown to give myself the best chance of it not cracking. After using these rods cold I can say with confidence they would work great with preheat.

May I use AC instead DC?
Brandon Lund (13 days ago)
If I remember correctly Mario, these rods can be used on AC or DC but if your looking to order some, I would check out their website to be sure. Cheers

yeah and what can happen is you grind it and it hides the crack because you have ground it.
Brandon Lund (13 days ago)
wrong. Grind first so you know where your crack ends. Your hole has to be beyond the crack.

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.
Brandon Lund (18 days ago)
Thanks man! I appreciate your kind words. I plan to get my hands on some cast rods and i cant wait to see how they flow. The manifold was more of an experiment on the basic process of applying a nickle filler to a cast part, (not necessarily a tutorial on what you should do to fix a manifold) but then some were saying it was not cast iron so I ended up switching our testing piece to a cast iron skillet to hopefully eliminate that cast iron / cast steel debate. Thanks again for the great information and comment!

Question. I have a manifold that broke between the 12 and 34 port on my SUV. can they be welded all the way back together?
Brandon Lund (21 days ago)
Cast iron can be tricky to weld and the only way of knowing is to give it a try. Some cast iron welds easily and some does not. If you plan to tray and weld it while on the vehicle, it is common to allow the vehicle to get up to temperature, then weld it and then then wrap in a welding blanket to allow it to cool slowly. I have a cast iron welding series playlist that might be helpful for you.

how about alluminium. is there a way to stickweld alluminium? is there available welding rod for alluminium?
Brandon Lund (23 days ago)
You can stick weld aluminum using DCEP. Its not pretty but it works. The rods are fairly expensive. Clean your material real good with a stainless brush and you need to preheat the part around 400f. It also helps if you have sacrificial tabs at the beginning and end of your weld that you can start / stop on.

You are incorrect about welding cherry red mild steel. Your undercut can also be cause by the too much angle on the electrode. If you purge the manifold while tig welding it, the weld inside will look nice like the outside.
Brandon Lund (30 days ago)
I'm confused why you would think mild steel cracks from being heated to cherry red and allowed to cool (this is exactly what happens when you weld) but I agree with everything else you said, including the importance of a purge when tig welding.

jason bourne (1 month ago)
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
Brandon Lund (1 month ago)

Not sure if they're still around, but awesome products Had a 1/16" ss rod max amp was 40, had a 120k psi tinsel & brass would stick to it. so w/e the application (i repaired cutting dies for the Hanover Shoe co) and has to splash a little brass on the cutter edge where worn.

Ocean Mariner (1 month ago)
When I learned, 1950s, after welding the cast iron was wrapped in an asbestos blanket so it would cool slowly. Small parts went into a tub of loose asbestos fibers. Shops and foundries that do a lot of cast iron welding usually have an oven.

+Brandon Lund Much better welders and rod today. New and better techniques. Lots of change in 60 years. I worked in shipyards, ships were steam and all the piping & boilers were covered in asbestos. But I still have 2 lungs.

Bad stuff! Before they knew the health hazards of asbestos. Ive been around asbestos quite a bit myself in the trades but I've always been careful. Hopefully it won't catch up with me. A couple of my viewers have mentioned the big ovens and if you have access, that is by far the best way to go.

Good video but you need to practice your aim with the slag hammer.

Nah, doesn't really matter. Just beat it. I usually use a needle gun but this is more DIY friendly.

A very good video...I weld, on occasion, learned a lot watching this and I really liked the little welder set...This was also a very good lesson in technique teaching as well...My thanks to the gent that made it.

hey im a pro welder. I'd never post a pic or video like that. if i did id add a warning. sum kid who isn't a pro welder mite c it & b convinced they can weld a load-bearing or pressurized cast iron part on their vehicle and it fails. They'll get hurt, GOD Forbid. Btw, there young welders - men & women - who can weld circles around me. No big deal. I had a feller ask me to "repair" a cast iron cooking pot. i refused. I trust my welds but I don't trust the properties of post-welded cast iron parts. I could have made him promise me he'll never cook in it and he does anyway & he gets hurt or sum one else does. To viewers: If u need a cast iron part welded, FIND A CERTIFIED WELDER. If it goes on ur vehicle, chuck the damaged one & buy a new one. DONT take any chances.

crappy unsat weld infused with slag

Mike Mullins I looked on your channel for your cast iron welding video and to my surprise I found nothing 😂😂😂 Nice try. GO troll elsewhere, or at least watch and learn before you make dumb comments.

Это отлично, поэтому что оно исправлено.

You should have sand blast it before you welded it
Brandon Lund (2 months ago)
+madbear3512 Thats a great idea! Here is the one that I use (except mine is red). It's just a little hand held unit that works really good. A 50 lb bag of sand lasts a long time. https://amzn.to/2PWTZ9a

+Brandon Lund Idk much about em. How much does a good one cost. Do you need a shit ton of sand. You should do a video on em.
Brandon Lund (2 months ago)
Although I do own a sandblaster, I feel that most DIY folks probably dont, which is why I did not do it that way.

Excellent repair method!
