reminds me of a story about a ship's engine with a broken piston top.. they were far from port..but had a well equipped engine room with a lathe..the chief wondered how they would affect a repair as he made himself a coffee...looking at the oil stove gave him an idea he "chucked up " the piston in the lathe and cut the broken top out leaving as much as he could around the edges he the turned one of the cast iron stove lids down just enough that when the piston was heated and the lid cooled the two fell together in a perfect marriage he said it got them home and to his knowledge was never changed...
You saw "cast iron" and "welding". I am still waiting for the cast iron. He welded that as if he wanted to get home early. He touched the molten pool with the tungsten just before he laid it on it's side. Then he TRIED to melt out the porosity. Did you see the sparks fly. He should have ground it out before finishing . I have no idea what filler rod he used, but it looked a bronze type. I think the piston may have been cast steel, which is why he could weld it the way he did. Should have used stainless steel filler wire, though.
He cut into that piston with a cutoff wheel like a bad ass. He surely has done this type of work before and probably many times. Nice job! That's a real welder.
Yeah I was thinking the same. You're really free handing the cutout with an angle grinder outside in your yard? You're either a moron or a special breed of pro, turns out it was the latter. Awesome video.
Wow cast iron! It's like welding porridge. I'm watching this with interest. I TIG welded a garden ornament that was cast iron screwed to mild steel but the thread had pulled. It just kept cracking. Preheating and stainless filler rod then left in a powder coating oven to cool gradually overnight got the job done. That was a school day!
Why the negativity in some posts.. This a very difficult repair that is carefully and expertly carried out. In most places this would be death of part failure, here, made to live another day.
Jennifer WhiteWolf I feel like he did an amazing job except for the last 10%. I feel that it would have been very easy for him to fill all those pin holes in especially with Tig.
tig needs the cleanest surfaces - he should have cleaned the area. Sanding, blasting, ... and in the end with aceton. Also clean the bead after each torch turn off. you also have to preheat the thing seems kind of crappy tig work.
lol there is nothing clean about cast.... Someone needs to go back to school or try a weld repair like this for themselves otherwise your comment does not hold any weight.
I have done this myself, I would have done a more thourough cleaning, Then placed it in my oven and pre heated it to 550f over four hours. Kept there over night. After welding replace in oven over night to reduce stress. I would have used my needle gun on the weld before using the hammer also to remove stresses. It works for me. ChiefD
I've done quite a bit of TIG welding of cast iron. I prefer nickel 99 TIG wire. A lot of good welders like brazing cast iron, though. They usually use a torch. A little pre heat and slow cooling seems to help.
i dont mean to be off topic but does anyone know of a trick to get back into an instagram account? I somehow forgot the password. I would love any tricks you can give me.
@Jaden Coleman i really appreciate your reply. I got to the site through google and I'm in the hacking process now. I see it takes a while so I will get back to you later with my results.
Difficult weld at the best of times, but I wouldn't have tig welded that. I've always welded cast iron with standard arc welders using suitable rods. Before welding the item is groved as necessary and heated to a very high temperature, somewhat less than red. The weld is hammered in the same way to stress relieve, then cooled as slowly as possible. I've welded several vises that have broken at the neck very successfully with this method. It is necessary that the item be made of decent quality cast iron.
That was a pleasure to watch, thank you. This weld is going to get a beating with high compression and with the heating and cooling cycles I am really curious how well it holds up.
Peening is a nice trick :o) I need to get into that sort of weld relief. Although, mag-ally seems to be my thing at the moment. Let the ally rod blob down into the surface and then work it in before the magnesium gets angry and leaves the party.
no preheat? you waited for it to cooldown? Like small welds technique? What was the additive metal? looks more like brazing then welding with high nickel content rod?
That is a hard weld to make! That piston top is so impregnated with extra carbon from being in high heat application where soot is produced from burning fossil fuel. That trash boiling out of that piston top will make it fight any filler metal flowing onto it.
TIG weld steel straps on the cam towers for additional strength for bigger camshafts, no preheat. Weld 1 inch then go to furthest tower and weld 1 inch. The idea is to let things cool off before going back to 1st weld. It's closer to TIG brazing than actual welding as the head doesn't actually melt, just "sweats".
Weil ich schon schlechte Erfahrungen mit massigen Teilen gemacht habe hätte ich den Kolben auf min. 200 Grad vorgewärmt. Aber er wird das nicht das erste Mal machen.
Schöner Nasenkolben! ob das die Wärmespannungen später dauerhaft aushält und mitmacht ist bei Krümmern auch oft ein Problem schön geschweißt und reißt dann gern wieder ein
Soo many internet welders that have never even picked up a torch...First off, Its a 12-50hp engine...there wont be too much stress on this piston. Also, he using aluminum bronze filler which means hes brazing not welding...His goal was to eliminate the crack so it wouldn't spread and fill in the crater he made doing so. Which is why hes brazing in aluminum bronze. Its not a structural repair, that's why there wasn't too much of a need to preheat. It could have been done cleaner and better, but this will do the job just fine for its intended purpose.
I dont know if he did preheat, but he didnt do post-weld cooling procedure....he stopped welding and then started grinding right away...And people there say, we are haters who say fancy shit
To answer the question.. YES! To minimize problems due to stress you must A Pre-Heat over hours, do the repair and then Re-Heat it up to say five hundred hold that for a few hours an then Reduce the temp fifty degrees per hr till you can remove it by hand. It’s little over kill maybe, but it’s always worked for me and my Grandad he was an old school Blacksmith coke forge anvil the works. I was in the Seabees for twenty Five years, you hang around Battalions, CBU’s, and NCTC’s long enough you learn just about everything you need. ChiefD
That's some premo pitting you got going on there. Personally, I would have touched up the cut with a diamond tip and a die grinder, so there was a smother surface to wield to. I am wondering though. On a piece like this, would he have pre-heated it?
This is usually true. A bit of preheat won't do any harm. Just remember that "cast iron" includes many grades. Some are easily weldable with minimal prep and common fillers. Some cannot be fusion welded and will require brazing or silver solder to be repaired or joined.
We used to re-crown pistons for ships and we had to heat them in the furnace for hours then put on our insulated gloves and turn the mig wide open and basically spray arc them. Even with the insulated bunker gloves we would still get huge water blisters on the toos of our hands, sucked but had to be done. Cool video.
+Max Maruszewski I'm guessing he used EZ weld filler. Just google it and you'll find the seller. He's reasonably priced relative to buying nickle rod. I've used it and it welds very nicely and does a nice repair.
D. Slater Cast iron is so hard to weld most welders will say 50/50 chance of it working. If you use conventional nickle rod(expensive!) you'll have to preheat, weld and if the welding doesn't keep the heat of the base metal up (engine block etc) you'll have to keep pre heating it till the repair is done then do a very slow post heat cool down. Real pain. The easy weld bypasses all that and you go strait to weld and your done. I've used it on engine blocks and exhaust manifolds. Had very good success with it. Don't get hung up on equipment. If you learn on a crappy old machine, you'll be an expert when you get a good one. Best of luck.
When you say soldering are you talking about using lead/tin alloy filler metal? I've never seen this process used. I've seen allot of brazing used in cast iron.
what kind of rod are u using to fill the crack?? how come u have not pre-heated the piston before u start to fill the crack with metal?? shouldn't you have put drill stop holes at the end of the cracks to try and prevent the cracks from continuing??

That is a massive piston. Lanz Bulldog is another one of my favorite tractors along with International Harvester Cub Cadet and Cub Lo-Boy
I would like to have seen the teardown and rebuild of the engine also . That was one heck of a repair 👍👍🇺🇸
Lanz bulldogs are old two stroke single cylinder hot bulb engine powered tractors, repair probably not that hard
My grandfather is 79 yo and still craving about the bulldog he drove to the scrapyard in the late 50s
Got this reccomended after watching the visio race video on big single cylinder engines
When he holds on to the guard on that grinder gives me chills. My Buddy almost cut his thumb off like that.

Peening the metal to minimize stress cracking.
Peening lol 😉

Whats the filler rod?
The fact that it’s cast and it came out that good astonished me
It would be great to be able to see the puddle.
Yes i was hoping to see the puddle aswell

Isn't it gonna harden the cast iron and cause more cracks? I don't know just asking.
Great job! Keep up the good work
Bro what the hell man i though you have sleeping effects
Just like how I would've done it, awesome work.
Yeah, great job. God help people who go near anything you weld...
Great video, music which seemed to suit the task rather well. I am curious to know of any pre and post heat treatment used?
Muggy weld 77?
Will this fit in my Honda?
+krap101 it will
maybe if you take back seats out
Put Honda engine inside the piston add wheels and drive it arround.
krap101 no it wont!
its bigger than your Honda.
Is the piston cast iron?.....if so why would you use tig over pre heat and braze???
I wonder what rods he was using?
Hey that’s a nice jacket dude, l would totally use it to ride my bike... (which l don’t have) 😰🤷🏽♂️ 🏍
What type of tungsten, Filler rod and gas was used?
That was some fine dentistry.
no preheat? you waited for it to cooldown? Like small welds technique? What was the additive metal? looks more like brazing then welding with high nickel content rod?
That is a hard weld to make! That piston top is so impregnated with extra carbon from being in high heat application where soot is produced from burning fossil fuel. That trash boiling out of that piston top will make it fight any filler metal flowing onto it.
instead of silicon bronze he should use aluminum bronze with ac to cook out the trash..
I use silicon bronze on cast iron Pinto heads.
do they hold? With or without preheat?

Very well repaired
Ive heard the joke of thwopping great big single cylinder motorcycles firing every other lamp post but this fires every other mobile phone mast!
what's the purpose of the weird shaped top of the cylinder?
This were the tractors that had almost a kilogramo of gold in the internals of the engine?
With which add martial you have welded it, is that just copper bagette, or type of material correct, I see that you weld it with the btig.
this is cast steel not IRON, isnt it? i am looking for castSTEEL welding tips and stick electrodes...anyone knows this stuff?
Would you heat the piston to 400'F before welding it and heat afterwards?

Why did you not pre-heat the piston? Did you use stainless rod?
Drill the crack ends to stop it creeping?
whats the reason why you hammer the weld??

Silicone?
Félicitation for your job of quality professional very good.
What was used for filler?
C'est quoi comme chalumeau ? un découpeur plasma ?
I am wondering what filler material did you use?? Thank you Kevin
Nice work Do You use stainless welding material and how many AMP do you have on the TIG welder👍
Was wird da denn für ein Schweißstab verwendet?
Butane lighter laying next to welding going on?
That's some premo pitting you got going on there.
Personally, I would have touched up the cut with a diamond tip and a die grinder, so there was a smother surface to wield to.
I am wondering though. On a piece like this, would he have pre-heated it?
I think he should have. Pretty hard to go wrong pre heating cast iron but you can do less than excellent by NOT pre heating.
Great job pal
looks like aluminum bronze filler rod with some awesome tig techniques
I am not a welder, but wouldn't it be better to heat the Piston with charcoal before welding to avoid embrittlement of the HAZ?
the weld is full of air bubbles? why?
So what kind of fillet rod is he,using,?
Another nice repair was it a weld or braze?
That's exactly what I want inside my corolla
222 mm? Maybe 225?
What filler rod did you use?
Brazing a piston?
Steel toed crocks?
And I always thought you had to heat cast iron up to weld it, learn something new every day.
This is usually true. A bit of preheat won't do any harm. Just remember that "cast iron" includes many grades. Some are easily weldable with minimal prep and common fillers. Some cannot be fusion welded and will require brazing or silver solder to be repaired or joined.

What is the fillermetal you use?

Looks great
what about lighter next to piston their low pressure but will explode
What alloy was used?
And that weld will has the same thermal expand index as the piston?
No but it's that or nothing when those pistons arent made anymore
