Cold TIG Welding of Cast Iron --- WIG Kalt-Schweißen von Gußeisen

[@gyrojomo]

That guy knows what he is welding and how to do it, unlike the critics. It looks like a cooling water jacket that has been split by frost. Most of the commentators below are criticizing the repair as if a full strength butt weld is required; they would take at least 4 times as long (plus time to re-read the Boys Big Book of Welding) and would want to charge 4 times as much. Watch and learn, guys, instead of criticizing a guy who has probably forgotten more about welding than you will ever know.

[@thomasmeier9448]

It may be, that this guy is a good welder. I'm sorry, but this is a bad repair of cast iron. I do this job (cast iron welding) since over 35 years, I have never seen something like that shit. I hope, this work ist just for himself and not for a client.

[@gyrojomo]

Thomas, if you look at the comments, some dont even understand the principle behind cold TIG welding. All the weld had to be capable of is holding the water in with a bit of thermal growth and some vibration. Its not a structural weld. Cooling water jackets are sometimes repaired with nonmetallic compounds like Chemiweld.

[@georgiojansen7758]

his comment in german says, follow the welding procedure and some important detail is not shown or mentioned, stays his secret or you find it yourself..now anybody know this secret??

[@jonathanlittle3012]

My understanding is that tig welding cast iron requires technique and knowledge of what metals to use. I sure would like to learn how to make cast iron repairs with my powertig welder.

[@65sgboogieman8]

Sorry gyrojomo, but porosity is no fucking good no matter what. You should never weld cast without pre or post-heat. I don't care what new gay bullshit they come up with, it's crap compared to the tried and true. Also he should be dabbing his filler a little more than his tungsten, this video is a joke. Learn how to prop your hand instead of waving it around like a fucking fairy

[@julianlaustsen1991]

why didn't u drill holes at the end of the cracks and grind down in the crack to fill up?

[@MrMac5150]

Should have been cleaned sand blasted, and ground a valley out first.

[@TufdogsPlace]

+MrMac5150 I see what you mean... Good call

[@FrustratedBaboon]

Yes. Will crack again.

[@ricardobenin7830]

did not v out crack and or drill a hole at end of cracks

[@daveprototype6079]

I agree drill to relieve stress an v groove for strength

[@eddiepiecart6030]

That unprofessional weld will probably last 40 years.

[@mikebarton3218]

I have full respect for the determination and ingenuity of this man, not to mention his patience. Yes, the armchair experts will take the bait, that was inevitable. But I can't help thinking that a little more finesse - like a vise and maybe a simple test fixture would have been a benefit. I watched it end-to-end though. Mike

das hält von 12 bis Mittag.

[@olipas2775]

Wahrscheinlich hält das 40 Jahre

[@leonardpearlman4017]

Controversial welding practices aside, it looks like there's something very special about that welding table! Anyway, nothing is more controversial than welding cast iron. I have an old book about only this topic! Unfortunately the best practice of the time involved a lot of charcoal fire and asbestos sheet, building a temporary furnace and so on. People used huge torches (high power, also physically large if only to keep you away from all that hot stuff). Probably works too, but... I live in Florida where it's already hot!

[@plumbcrazy375]

That was funny you did what several other people said not to do but looks good to me

[@mannuel9165]

mic-ibarra from mexico what rod did you use ? aluminum bronze 309 ss or something different ?

[@williamgibson1269]

i can see so much wrong here. dont even want to go there

[@thebrokenbone]

i can`t believe it! nice job! it goes against almost 90% of what i have been taught but seems to work for you, awesome. are you doing it AC or DC? nickel rod? please if you have the time comment on this. thanks for sharing!

[@aguilayserpiente]

the pinging sounds are the cracks forming. Sadly this antique is cracking.

[@burakyunuscetin2331]

Sounds right.

[@MrMac5150]

Should have preheated the metal to take the tension off.

[@killallfornothing]

You can go without pre heat but only short distance, and if U pre-heat cooling down in sand or ashes, plus drilling hole on end of crack to stop going further...

[@paulerickson1906]

Beautiful. Much admired.

[@sverreeriksen1982]

interessting weld working, is that a cast iron filler you are using. mvh sverre eriksen

[@KiranDigavalli]

Warum haben sie ein "v" in der nähe von den crack nicht geschnitten, und warum haben sie die werkstück nicht vorgewärmt? Dennoch ist es eine interessantes video!

[@daveprototype6079]

Is that silicon bronze tig rod? Or 70s02

[@Peter-V_00]

If that was bronze wire this guy needs schooling.

[@daveprototype6079]

+MerlinxPV either way it could have been repaired cleaner.... Wouldn't hold my breath on this one.

[@Peter-V_00]

Very true

[@slpknt8645]

Die Hammerschläge auf einer WIG Naht.. selten so gelacht

[@osaelbarrantes8060]

Gut arbeit, aber Zeit wird zeigen.. Dankeschön und Gruß von Costa Rica. ANTWORTEN

[@thehereticofaustria3803]

Selten so einen "Pfusch" gesehen, alle Achtung!......

[@mrjodoe]

reinigen der Risses, Vorheizen des Werkstücks...

[@OrlandoRodriguez-fg6hb]

Bro, are u using EZ Weld as material for this?

[@ІгорТкаченко-й1е]

А хіба чавун перед зваркою не потрібно прогрівати?

[@fredfeuerstein5929]

Sollte man nicht vorher ein paar Heftstellen machen ?

[@adriasava695]

curatat inainte,slefuit,gresit sudat imi pare rau!!!!!!!!!!!

[@TufdogsPlace]

Nice work !

[@MrMac5150]

+Tufdog's Place Not the right way.

[@daveprototype6079]

+MrMac5150 definitely not the right way

[@MrSteve05m]

erstens die naht sieht mal richtig scheiße aus und wenn man das Material vor dem verschweißen richtig sauber macht bekommt man auch keine Poren

[@danielostle9460]

Looks like a butcher prepping kangaroo for dog food but if it works

[@carryitaround]

This repair will hold just fine unless they allow it to refreeze.

[@65sgboogieman8]

Ha. Yeah, what a great repair....................

[@westpaddy76]

Sollte am Anfang und Ende des Bruchs nicht gebohrt werden. Und sollte das Aushämmern nicht laufend gemacht werden - einige Zentimeter scheißen - hämmern - schweißen ....usw.

[@kolbenschieber]

einige Zentimeter scheißen... Jo!

[@westpaddy76]

das hab ich jetzt nicht verstanden?

[@westpaddy76]

Achso, lol, das hab ich falsch geschrieben. Hahaaa. Sorry. Schweißen...schon klar *gg*

[@Peter-V_00]

That repair will fail, it should have been cleaned better then repaired with aluminum bronze tig or flame applied braze.

[@bingosunnoon9341]

It's fine. It is not cast iron.

[@Peter-V_00]

@@bingosunnoon9341 Must be why the video title says it's "cast iron" because it's not.

[@bingosunnoon9341]

​@@Peter-V_00 I didn't catch that but it makes sense. Every cast piece I was given to repair was said to be cast iron. It never was

[@Hedley27]

Für mich sieht das aus als wäre der "Schweisszusatz" Bronze . und kein Stahl

[@jestemtere9140]

tragedia. udziadowane niesamowicie.

[@andreipetrasun2691]

I think beter braze, than weld cast iron:)

[@РоманК-с7й]

Иоганн Штраус звучит в тему..

[@robertward1993]

I been welding professionally my whole life....that was painful to watch

[@robertward1993]

@Christopher Smith Love ya dude.....I meant no I'll will or harm

[@robertward1993]

Total respect for what you do from one welder to another

[@welderlogic1806]

Right there with you. I've been welding 37 years now and I've never seen someone do a worse job than this on cast iron. Dirty material, no preheat, way too much welding in between stops, not paying any attention to interpass temp,TIG welding when you should be using stick, He didn't even try to dig the crack out of the metal. Not even drilling a hole at the end of the crack. He just threw a cover pass right over it. Wow. I hope the people that brought that part to him didn't pay him for his work.

[@thomasmeier9448]

Shit repair.

[@ludditeneaderthal]

An unpressurized water jacket on a hot bulb 2 stroke diesel. It probably sees a 120 degree f temp variation, zero mechanical stress, and seasonal use. That "all wrong" (according to the comment experts) braze and peen tig job will undoubtedly outlive the "experts" who naysay so loudly

[@vor3484]

was daran ist jetzt kalt?

[@hummelu6]

Ich denke mal das sich das Kaltschweißen darauf bezieht das der Zylinder vor dem Schweißen nicht aufgeheitzt wurde, denn beim WIG Schweißen ist der Wärmeeintrag doch weniger als bei E-Hand Schweißen

[@faktorfred2545]

Kompletter Murks !

[@westpaddy76]

+Faktor Fred Woran kann man das erkennen?

[@faktorfred2545]

Schweißstelle nicht von der harten Gusshaut befreit. Bruchfuge nicht ausgeschliffen. Werkstück nicht entsprechend vorgewärmt, wie für solch ein Teil erforderlich und unter Materialspannung geschweißt.

[@ocintataable]

Niet schoon gemaakt, slechte las

[@ronniebrown8775]

Thats a welder

[@killallfornothing]

It is not professional way of doing this.

[@65sgboogieman8]

yeah a real shitty one

[@Tauchboot]

Na alter Schwede sowas habe ich noch nicht gesehen .jetzt wissen sicher viele Leute wo man nicht hingehen sollte um seinen Zylinder Schweißen zu lassen. Dieses Video müsste eigentlich heißen, wie man es niemals machen sollte.

[@sascha1839]

Tauchboot wo ich das gesehen habe musste ich gleich lachen was das für Typen sind die ihren Schrott hier für Qualitätsarbeit halten der Typ sollte in dem video lieber Briefmarken sammeln oder ein anderen Schwachsinn aber alle Filme sind solche Reinfälle von diesen Hirten
