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.

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.

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.

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?
This were the tractors that had almost a kilogramo of gold in the internals of the engine?
Isn't it gonna harden the cast iron and cause more cracks? I don't know just asking.
Great job pal
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.
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👍
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.
Hey that’s a nice jacket dude, l would totally use it to ride my bike... (which l don’t have) 😰🤷🏽♂️ 🏍
It would be great to be able to see the puddle.
Yes i was hoping to see the puddle aswell
Is the piston cast iron?.....if so why would you use tig over pre heat and braze???
Well done!
Félicitation for your job of quality professional very good.
Looks great
What kind of filler rod was used have some cast iron to repair myself
Another nice repair was it a weld or braze?
what's the purpose of the weird shaped top of the cylinder?
Why did you not pre-heat the piston? Did you use stainless rod?
Muggy weld 77?
well that's what i'm calling a piston!!
Right do they even make pistons like that anymore
It's a 1 cylinder 10L motor
@@zacharyp10 Its a 2 stroke unit, you shouldnt forget
Ive heard the joke of thwopping great big single cylinder motorcycles firing every other lamp post but this fires every other mobile phone mast!
Butane lighter laying next to welding going on?
Why is there such a big difference in the material where you weld and the casting? Looks like your weld doesnt blend properly? its 5 years since i welded last and we usually welded aluminium so im not experienced in this? Why the coloring difference?
What type of tungsten, Filler rod and gas was used?
Are you using a stainless steel welding rod?
Was wird da denn für ein Schweißstab verwendet?
Just curious, why did you choose TIG over stick?
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.
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.
Look at the filler color as he peens... it's a bronze braze
Excelente trabajo .
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?
what's the patches on your jacket looks like some type of military patchs
I love that jacket
а как так????? не разогрел? не почистил ? так нельзя делать .....!!!!!!!!!!!!!!!!!!!!!!!!!!
Fakt dobrá práce !
My question is don’t you have use ot a milling machine.Ron in Ohio usa
Guss schweißen muss man auch erstmal können, also Respekt👍👍👍 Gutes video
An sich hast du recht. Aber anscheinend auch keine Ahnung. Wenn man Guss schweißen will muss man es Spannungsarm glühen und es wird bei ungefähr 200 Grad Materialtemperatur geschweißt UND auch NICHT mit WIG sondern immer Autogen. Das was dieser Herr da im Video macht ist total falsch. Das hält auch bloß von morgens bis mittags.
@@Nordmanntanne96 Da hast du recht, Ahnung vom Gussschweißen habe ich nicht wirklich, habe ich erst ein Mal gemacht. Aber Do it yourself finde ich immer gut. Danke für die ausgiebige Info, denn das mit dem Glühen wusste ich gar nicht 😊👍
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.
the weld is full of air bubbles? why?
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.
very nice video. it would be great if you could show us actual torch work with covering camera lens with protective glass...
It also would be great for the camera.... :P
So what kind of fillet rod is he,using,?
I wonder what rods he was using?
Is The Funeral March appropriate music?
Did you use copper
whats the reason why you hammer the weld??
222 mm? Maybe 225?
What was used for filler?
C'est quoi comme chalumeau ? un découpeur plasma ?
was nimmsten für nen draht ?
I'm curious too. So no end of crack drilling. Brazing cast iron which you can do. But how is that low melting point bronze going to hold up to the high heat in the cylinder with at least 23 to 1 compression? That is what I am curious about. Not the craftsmanship.
Из какого материала сделан присадочный пруток?
what about lighter next to piston their low pressure but will explode
isnt this from the engine that can idle at 0 RPM?
good job j liked tig
Not badly done, But I think I would have taken out a larger area, I suspect some of the area around the fix is going to fail . I would have ground down all of the orange peel areas and used a light acid to see if I was into good metal or not. Then tig the snot outta it/grind /flap wheel it all out .
What filler rod did you use?
benny hill style hammering
What wire and gas are you using
Steel toed crocks?
What about the weight difference ?
looks like aluminum bronze filler rod with some awesome tig techniques
