Repair cracked truck chassis by excellent welding skill

quite beautiful job, please enjoy it.

[@matts8023]

Seen a lot of repair videos on KZbin that were impressive because they worked...this was different. This guy really cared and di a great job. Was instantly impressed. Even little game can recognize big game!

[@gckshea]

This man is truly an artist. Looking at other repair videos of his, line boring, new bushings, stress fracture repairs, reassembly, and finishing...all top notch!!

[@CristianZamora]

All top notch trash

[@davidrichards3605]

Nice job but I think I would have added some strenghtening plates as a backup precaution.

[@BlackKnight-ll8qh]

Honestly, I was not expecting this to be that great. He truly amazed me with his work. Good job.

[@ddiablolll]

Many ways to fix yes. But fixing it with the tools you understand, is the best way. Good job

[@markh3279]

Nice, the heated section is now weaker.

[@autobody_experience]

I did trailer repairs for 45 years and we always sleeved the inside. It’s a lot more work but we take our safety a lot more seriously here!

[@arleigh31burke-zc2om]

it was sleeved already didn't you see?

[@jeremynull6652]

Some people dont realize, truck frames can have harder spots and softer spots depending on how they were designed. When hardened steel bends too much, it cracks. The only eay to fix it is too keep repairing it.

[@jankriz4611]

Good job!!!

[@dannmann17]

You are the master with a cutting torch👍🏻🇺🇸

[@user-cx1fp4jy7l]

хорошая работа ! а вообще марки сталей из которых изготавливают рамы для грузовиков НЕ СВАРИВАЮТЬСЯ А КЛЕПАЮТЬСЯ ИЛИ СОБИРАЮТЬСЯ НА БОЛТАХ бывают конечно исключения .

[@user-sd4qj1mo8k]

Вообще варится.. Но ввартвается кусок от рамы... Нормальными электродами определённым током... Но и после этого есть элемент лотерейеости... Затерают.. Красят.. И продают.

[@user-tx4fd5bn8j]

Корень с отрывом варить такое себе, и шов зря зачистили+ сверху усиление надо было наварить. А это наебка на продажу...

[@user-ud4gx8ye4q]

Ошибаешься, мой друг, прекрасно варится и хорошо работает рама после этого если соблюсти всю технологию( электроды, металл и т.д). А усиление конечно зря снял! Скорее всего точно на продажу.

[@Orc-nr7zn]

​@@user-ud4gx8ye4q у меня три года ходит без проблем, варил как тут показано примерно , снаружи тоже затер покрасил чтоб красиво, но с нутрянки наварены ещё пластины. На сварщика не учился - прижмет научишся всему...

[@user-fv2dc2wn8p]

​@@Orc-nr7znвесь смысл в усилении.

[@brianpatrick8441]

I know a pro when i seen one!! This guy is a pro!! Notice the fit? Thats how it's done!!

[@scottpitters3624]

It’s against DOT regulations to weld on heat treated truck frames because they are heat treated

[@blackened872]

I have a weird feeling this guy is out of the DOT’s jurisdiction

[@armandogonzales1365]

Awesome good job my only critique is grinding down the cap

[@traderman4378]

Nice job!!

Svaka čast🎉

[@dwhallon21]

From my point of view, he did an excellent job, cut out the old. Replaces with new in non cracking way...final product not only looked good , but was good

[@thomassullivan1676]

Need continuous welding both sides...right weld wire too good fitup

[@danobryant7740]

Very nice job indeed

Perfect grinder smooth, paint it up drive it for a month, now sell it.

[@user-jv8je9dr5e]

Хорошая работа , молодец сварной! Всё сделал аккуратно.

[@Ma_X64]

но неправильно

[@user-wz1sx8zm3v]

​@@Ma_X64почему не правильно?

[@Ma_X64]

@@user-wz1sx8zm3v потому что это делается не так. Тут у него основная цель была, чтобы было незаметно. Но оно через некоторое время снова лопнет вдоль сварочного шва. В таких случаях делается овальная или ромбовидная латка поверх трещины, чтобы сварной шов нигде не шел поперёк балки.

[@hotshotdave5159]

Instead of welding the crack and then reinforcing it with plates on the front and back, and now you have 2 welds that could possibly crack

[@wtfatc4556]

Yes but they are polished ! So you have 2 weak welds

[@drallersouldust3054]

it's a repair bro, a lot of truck owners don't have that much capital to replace the whole channel and it cost too much and it will take longer

[@fisicamatic]

I love when Americans or Europeans need to discover there is a whole world beyond their country and their life style. This video represents more than 50% of the planet. Or do you think we have all sort of tools and materials like you have?

[@leodcaribbean6224]

​@fisicamatic my guy the second you said Americans or European you lost your argument! you dont need to hate on others to show your point of view! your comment only shows your lack of education!

[@gasolinaoleo2349]

Pretty good 👍😎

[@gonzalolopez7199]

exelente trabajo saludos

[@cefkungfupipewelder1568]

Excellent work

[@andywells397]

Grinding off the cap is not a good idea. Its prone to cracking. The cap was neat enough to stay, good job though.

[@gabex59]

Actually the cap is a stress riser. Proper way to repair is grinding cap flush to base metal as he did.

[@obfuscated3090]

Caps above the surface are acceptable per many codes but must not be excessive. His would have passed AWS but no harm in grinding them and he properly polished with a flap wheel without reducing thickness below base metal. Tidy work and ample for the task.

[@shanegray7739]

Good job, I would run atleast 5 horizontal welds across the repair then grind flat, doing so changes the grain structure of the chassis further reducing the chance of cracking, you can see this if the weld is X-rayed,

[@thewayidoit8895]

​@@gabex59 don't tell a pipeline welder that.

[@user-xm5ld2qn9r]

Замечательная работа.

[@letcikigor]

Super👍

[@bigears4014]

Nice welding

[@maximilianohernanorioli705]

Muy bueno

[@ivanmiheev4255]

Не понимаю зачем вырезать. Ну прорезали бы на самой раме трещину шире. И через ее обработал внутряк. Проварил зачистил. И пожалуйста делай наружную трещину.

[@ninjayacdan]

Problem is, it doesn't matter how well you weld truck frame. That weld will always be a weak point unless you replace the entire frame strut...

[@joepierrepierre8104]

...And add fish plate!

[@mikewarpula911]

That repair is wrong nice job on patch and weld,now just gave it two places to Crack from.needs reinforcement

[@shawncozad8565]

Not if you use bubble gum as a reinforcement. But it has to be twice chewed. A lot of poeple dont know this.

[@jeremynull6652]

Typically it's not the weld itself that becomes the weak point after a repair. The weak point is usually the steel right next to it.

[@ninjayacdan]

@jeremynull6652 exactly, because the heat treatment has been ruined by the welding.

[@hubertrobinson8825]

The crack just disappeared

[@user-tx8lg6ni5s]

Судя по сварке с отрывом, электроды с рутиловым покрытием.

[@sekatyoukko69]

Nice work but never weld a truck frame. The correct way is to make a new piece and bolt it on.

[@vitaliiom2318]

Гарна обманка на продаж. А так пропрацює не довго

[@Kevin-qo6jw]

Its just gona break one the side of the weld it ruins the heat treating if the frame breaks you get a new fram rail

[@johnr5545]

God bless

[@dennismaloney7241]

That's a frame; it should be heated treated. We always heat treated locomotive frames on the railroad, and they weren't under as much stress as a truck.

[@user-nr8jt4jy4u]

👍👍👍

[@user-mp7ji8nh7u]

Не бита не крашена😂😂😂

[@grade8fabrication]

Nice repair but looks like it was all welded with a 6010, and never a 7018?

[@donaldwhite1928]

7018 is the way to go 6010 doesn’t have the tensal strength truck Frames aren’t mild steel

[@teresadasher939]

Isn't it against the law to repair a chassis crack and use the vehicle again

[@Tom-90210]

RIP weakened heat treated frame rail 😢

[@michaelippolito6778]

Frames are tempered this is not the ideal situation. But it works

[@jairoluna4477]

Ese trabajo esta bien quedo muy bien pero se vuelve a estrellar el chasis con el tiempo o es bueno soldar en un chasis y me os en un camión de carga pesada aun que si quedo muy bonito el trabajo con mucha limpieza

[@komsomolec1]

The cracked place should be reinforced by weldind additional steel plate.

[@hanselgretel8563]

Please start using DC welders with 6011 and 7018 rods. Instead of doing everything with 6013

[@leandrokingtorneadora]

Top

[@jamesedmond3351]

This frame has never been cracked or broken, honestly.

[@conradwilliams8302]

In America this would not be a repair it would be a replace job .. gotta love these third world places where safety just isn't a thing..

[@cab8188]

I don't understand this dab dab method that seams to be common to overseas welding videos ?????

[@alexscott730]

Lack of knowledge

[@Last_of_my_breed]

This guy is very skilled and understands metal very well and how it's prone to break.

They would have had a field day with E Lancs bodied buses

If only the English was excellent skill

[@baazigaj9125]

hi, which rod you used?

[@weldingartist55]

Domestic brand "Jiashi 100". Sorry for my late respond

[@user-rg9qt8tz1h]

Надо было краской покрасить и все на этом.

[@r.hernandez6152]

It might hold.idk though!

[@Dave-tm8rp]

Shouldn't have ground the weld it just made it weaker

[@davidbottles3035]

That was a huge no-no. I don’t care how good he is, no welding on the truck frame.

[@williamnelson2332]

Never weld on a truck frame. Tempered steel

[@alexscott730]

And cast from a mold

[@epiphgd4302]

Jb weld would sort it.

[@totalyep]

Truck frames are heat treated and should never be welded.

[@Lucas-ix8bg]

I wonder where this truck is today? Down in a ravine or in a scrapyard?

[@alexscott730]

In the ravine next to the scrap yard....lol

[@user-jh6du6xv9d]

Как новая

[@peteharrison9816]

U should have cool it with burnt motor oil

[@kevinwalls19]

How did he only cut through one skin on the chassis how did the torch not blow through the second one 🤔

[@danielelliott3659]

It was rusty underneath. It would be hard to cut both pieces at one time an it would look pretty rough.

[@obfuscated3090]

Practice! Every repair welder should practice cutting on scrap frames. It only takes a few hours to get good with a torch and it's fun.

[@user-sp3gq1up9n]

The liquid didnt blow through the second skin.

[@markspence20xx]

There is a contact resistance between the two pieces of steel. The piece below did not get hot enough to cause it to burn. I had to cut a trailer like this once. Burning two layers of steel is problematic.

[@sanek9894]

Это проверенный способ,не сомневайтесь.мастер знает свое дело!

[@dennisdethloff7467]

Replace the rail

[@josemartins4087]

Show

[@dexterjsullen]

Why didn't he just weld the crack instead making more joints of failure (putting in a cut piece

[@PhunkyChikin]

It will fail again at the crack location if simply welded back. The patch puts parent material back in the high stress area where the crack initiated.

[@dexterjsullen]

@@PhunkyChikin he didn't reinforce it, still the same thickness, so that stress still exist in that spot (but I guess new material)

[@exploreindia9957]

Number??

[@markspence20xx]

Great job! I would not have ground the weld flush, however.

[@alexscott730]

Exactly.He automatically made it weaker by grinding those beads flush like that....

[@MrTench8]

Leaving the welds on would have been stronger but he clearly wanted to disguise the fact that it had ever been cracked!

[@thisisyourcaptainspeaking2259]

Crack kills.

[@DS-Turbo]

So instead of fixing one stress crack you made 2

[@user-gv3zo9uq1e]

Just for sale!

[@clist9406]

Do not heat or weld in this area

[@williampage2561]

We junk cracked frames in America

[@alexscott730]

Because we have road regulations based on common sense.

[@rolandgeb9970]

It might look nice or even professional but it's not. One doesn't weld this truck frame to "fix" it but even if it would be a thing, over-head welding is weak af. If a Austrian mechanic would fix a truck frame like this and it fails some time after (and it will fail) the poor mechanic will be in a lot of trouble...

[@Pinky_Staines1947]

Stop overloading the truck!!!!!!!!!

[@surfblue100]

[@mrt227zxr]

These should not be welded, you should fit a channel in side and out and bolt it.

[@georgegrill3262]

To be strong, you still need to bolt a fish plate over it!

[@gregorymainville4039]

Great repair, I was thinking fish plate as well,welded though 😄

[@goatsinker347]

Isn’t the triangle shape bad due to sharp corners? Should it not have been the shape of an inverted parabola?

[@obfuscated3090]

The corners after welding are not truly "sharp". Reinforcement plate customs vary but that example produces a longer, stronger joint than a butt joint while removing metal adjacent to the original failure which also likely has internal damage. He used an "upright L" reinforcement which are widely recommended for dump trucks (page 11): www.gmupfitter.com/wp-content/uploads/2021/06/2018_Chassis_BstPrac_093017.pdf

[@lanebigham6570]

I am not a welder but I have had to use the services of those who are both professionally and privately and it is my experience that if a welder doesn't want to weld something they tell you it can't be welded but if they do want the work they tell you the weld will be as strong or more than the original steel

[@kwacz]

Or sometimes they cant weld it due to skill level or experience. Not every welder is skilled at everything. Some people are better at certain things than others.

[@ChevyConQueso]

​@@kwacz Yep. Same as doctors, lawyers, and mechanics. There is just way too much to know it all, and they damn sure don't teach you everything in school. You want the guy you're about to hire to be honest. You can always get a second opinion.

[@williamgibble8361]

I guess the guy is only useing what he has, but electrode welding is not the recommended process for repairing high carbon steel vehicle frame. Reason being it's a much hotter process causing to great of an heat effected zone in the high carbon frame metal , Mig is the preferred process .

[@juguetecaro3910]

Terrible job 😅😅

[@mikewhitman745]

Garbage job. Not done correctly, it's still a massive weak point in the frame. It needs to be plated.

[@CristianZamora]

It WILL NOT hold... it IS going to crack. Truck frames are heat treated... all he did was make it MORE brittle
