Prevention and Control of Distortion in Arc Welding

[@christianlewis7055]

Nothing like old instructional videos, they always explain things best.

[@MrShobar]

It was a film.

[@francismarin8905]

You are all right

[@talleho8445]

Agreed, the little shrink cartoon has very good visual explanation too. Great education film

[@deepaksinghkanyal7141]

Yes, even the best video on Differential is also a old video from 1950s, best videos on fluid mechanics are from 60s. Old is gold

[@SotraEngine4]

That said, it did omit things that are extremely important which would be dicovered around 20 years later

[@robertthomas6127]

Some how I get the feeling that the voice of the narrator in such videos is always the same guy for the last 100 years.

[@aerialrescuesolutions3277]

too funny

[@ElTurbinado]

its true they keep his head preserved in a vault and force him to narrate instructional videos lol.

[@bodiemaxwell2717]

You all prolly dont care but does someone know of a tool to get back into an Instagram account..? I was stupid lost the password. I love any tips you can offer me.

[@oddborofiend]

Because it is.

[@bunnyfamily8]

I am so glad I didn’t exit this video once I saw how old it is. Why can’t all instructional videos be this entertaining and informative. This will help a lot.

[@SOLDOZER]

This video is actually pretty good for being 75 year old. Explains better than a lot of KZbin videos.

[@55Barcelona]

I must say that you have done a superb job at being an audio video archaeologist recovering and restoring old teaching information so it may remain in our archives forever. Thank You from a new to welding, 60 year old student.

[@carlitosgy6]

the release date for this video was12 april 1945, i love this kind of videos,they teach in an easy and funny way

[@kelliewood5245]

+carlitosgy6 Cool video. Even with such an old video I can learn something applicable to my (relative) new everlast inverter welder. I don't even think they had inverters back in 1945!

[@snoopydoggy5196]

Your right I don't think they did. LOL. I compare the features of my everlast welder to this video and I can't help but marvel at how far they have come. It is amazing though how much I can still learn from such an old video.

[@freddyruauw1509]

Video by WW II 😂

[@robertthomas6127]

carlitosgy6 … One can assume that over the 5 years prior the Industrie accumulated massive experience and had a great need to train new welders to move forward.

[@jxh02]

I was going to guess 1945 from the mention of Shasta Dam, under construction from 1938 to 1945. Also that E unit has a numberboard on the side, which makes it an earlier one.

[@cliftonballad1634]

Around 7:33, the * incoherent * is called a fleet( as in fleet of ships) fillet weld. It was a style of welding that produced deeper penetration than normal fillet welds. It was partly the type of electrode used and partly how much amperage was applied.

[@CinnamonGrrlErin1]

I went to elementary school in the late 80s and they still showed these types of old film strips (probably because I had the same teachers my dad had in the 60s; I swear after every grade I passed, a teacher would retire). I'm almost 40 now, and I am very grateful I got to watch these before TVs on rolling carts took over; they're charming and still really informative.

[@emostorm7]

Im about the same age and we had tvs on rolling carts, what's that got to do with anything bro?

[@ninjaman1255]

These vids should be taught in school all around the world ...... I'm from the Caribbean and theses vids makes more sense than my teacher lol

[@davemeikle7037]

I was sceptical about this video when I started watching it, but its very informative and explains in great detail the problem I was seeking to overcome. Thanks for posting it!

[@petermathews3474]

Even today These Old instructional videos are still the best at explaining things

[@jasonspangle7180]

Back-stepping... Brilliant!

[@mihailfelixdumitresc]

Clear explanations back in the day; why is it that today this is getting harder and harder to be concise and explicit enough at the same time ? Teachers need an update of their software of the mind so that to be able to get a message across as effectively as these guys did back in 1945.

[@jtq69]

Good old basic instruction from a generation that got work done quickly and accurately

[@rogercarrico4975]

Got a project to do where I suspect warpage will be a factor. This is exactly what I was looking for. Perfect, thanks!!

[@Ritikkumar-mq3fm]

Best explanation ever regarding welding distortion. perfect. never expected that Disney will ever produce a content related to academic or engineering purpose.

[@petermcmillan1773]

They did hundreds of this type of video for many industries, it was a very lucrative part of the business.

[@nidhin595]

It's a superb video to understand the distortion of the weld.

[@Andrew-qo6br]

The method of delivery may be old BUT the message is timeless. Was I the only one who expected Bambi to walk across the screen?

[@skumancer]

This may be old, but it's still valid and very very informative.

[@Amp661]

Good information is ageless. I'll still watch this over the newer vids.

[@javatreker]

Thanks for sharing the basics. Too many people overlook these basics.

[@brzojekawasakic9856]

Great!!!!!! So many videos about shrinkage...but old one explains the best!

[@lazydesmond8240]

they showed us this for orientation while making boilers for cleaver brooks. great video

[@mddenis1]

It was so interesting. Thanks for saving this video for broader audience

[@TorBoy9]

awesome video. I've not seen a more clearly explained vid on welding shrinkage, thanks!

[@ecollins92]

i love these old videos they make way more since then all the scientific explanations. theirs alot more of these videos on youtube too

[@yollopukki6998]

Still works the same after so many years.. very practical physics

[@drewbeirn7704]

Only one additional note to this video needs to be made. If you overconstrain an object you can push the internal stresses past yield and cause cracking. The worst case is overconstrain just enough that the internal stresses are close to yield and the calculated design strength of the joint is lost; unless a stress relief operation takes place post weld. People who miss this point often overconstrain welds then scratch their heads when they crack or fail prematurely.

[@AWDJRforYouTube]

OLD SCHOOL IS THE BEST SCHOOL!

[@spicytuna13]

Great video. Made me understand distortion a lot better now.

[@AprilFool13]

This is awesome! I was shown this video in trade school and I've been looking for it since. Thank you very much for posting this!

[@AlphaFlight]

people would be surprised to see how little has changed since then and now. in the sense that all these rules still apply. it's crazy

[@carlsaberhagen628]

The laws of physics haven't changed in the past 70 years.

[@SotraEngine4]

Except we now know how cracks are formed. Cracks are very important to know about and cracks absolutely loves welds. Especially clamped welds with residual stresses

[@raulmarin8704]

I like to say this is very very good video of how to learn welding

[@ludditeneaderthal]

George: I had shrinkage Jerry!!!

[@procityking4144]

Great video still used by many educators!

[@weldtight]

I love this old instructional video!!

[@MetaIIica93]

Many people are welding from left to right as its "easier". But i was taught by way more experienced welders to ALWAYS go right to left and from the bottom to top for better penetration values. Im not that experienced but i was lucky to get a job in a company which produces sections for coal mines which are installed 1100 m under the ground. Im assembling and welding "details", but every night when i have some free time i always sit in the cabin and trying my best to become a much better welder.

[@Gavreeli]

MetaIIica93 What does left to right or left to right have to do with penetration?

[@boomguy3708]

+Gavriel Dorian It's not as much left to right as it is pushing vs. pulling the bead. When you pull the bead, you're undercutting the metal from the heat of the arc, giving you better penetration. If you just push the bead, you're not going to undercut the metal before welding over it.

[@Gavreeli]

+boomguy3708 thank you. I understand the effects of pushing vs pulling / downhand vs forehand, but that guy was saying left to right and so it wasn't clear what he was trying to say.

[@SOLDOZER]

MetaIIica93 What moron told you right to left gets better penetration? LOL Morons...

[@gunchief0811]

MetaIIica93 your awesome keep it up.

[@plasmahead2]

Awesome and thank you for posting this! Do you have any more?

[@1978garfield]

[@b2major9th]

You can't beat these old instructional videos. Produced at a time when this nation had a bright and unlimited future based on its seemingly unlimited industrial power. Too bad it is not like that any more...

[@Kruglov762]

My metals teacher assigned this as an homework video lmao, was great

[@gunchief0811]

world war two welders saved the day. they made a new fleet of ships in record time. and we were able to fight on two fronts. Pacific theatre and European theatre. our welders made ships and therefore we won the war.

[@SotraEngine4]

Unfortunately a lot of the Liberty ships split in two due to insufficient knowledge about how cracks behaves

[@stefanlucas6978]

What a gem

[@ianmorado8865]

Mr. Shrink sure can be helpful!

[@SotraEngine4]

It is clear we have learned a lot since then. There is no mention of residual stresses and how damaging they can be when permanently clamping the area around the weld. Or the cracks that this can form. But how could they? This wouldn't be discovered for another 10-30 years from when the video was made

[@edwardcruz5187]

do you have any more videos ? thats was cool thanks !

Funny educative video! :)

[@gilgammesh1]

Ha remember watching this in college 5 years ago :)

[@KuzminSergey]

16:38 Please explain me how that one works. You weld top and bottom flanges - they will pull flanges inwards, reducing distance between flanges. Now you introduce gussets between flanges and weld them as shown (inside), so they'll pull flanges even further inside... i am confused.... I'd rather weld gussets on the outside...

[@smellsalotkid3357]

Thank you

[@7rixee]

Please explain as if you were to a child, always works for me. I suppose there's no shortcut then.

[@TheOwningsberg]

I don't know for sure, but isn't "Make shrinkage work for us" not really used much at all today? I mean I haven't really heard of that anywhere else. Can anyone think of a modern application for that?

[@drewbeirn7704]

Do this all the time with setup. Was making some T brackets and the Engineer was standing next to me making sure it was going to be perfectly square. I let him set it up, pull out his square and get it just perfect. I smiled and welded one side of the T joint he about jumped out of his skin when he saw it distort to one side. I told him to calm down. While the joint was still hot I welded the other side in the opposite direction. His mouth dropped open as he watched it come back to square. He was like no way... Pulled out everything, checked it and was completely shocked that it was a perfect 90. Many engineers should take the time to learn how things are actually made instead of trusting their pretty computer models.

[@SeamlessFab]

If you can.. Do autogenous tacks first at opposing pieces just to hold. Then go back and do filler tacks. Seams welded outwards, fillets last. I weld frames all the time and they’re dead flat. If your part rocks and isn’t square you failed.

[@nomenemo2921]

I started thinking it was funny old times stuff and ended I could not believe my eyes. it's so useful because it's the same today. but there is a very important thing they did not say or explain well: we call it "making points", it's when you weld deeply just one point on another side of the main first welding, where it could hold the piece like it was clamped. yeah they said that about that complex tower structure, but they should explain well how it can be used also on simple pieces to weld.

[@humbertoarroyogarcia]

great

[@freddyruauw1509]

Old video but is good.

[@schmalzilla1985]

So can you get away with not chipping the slag out? They showed a guy doing the back stepping, and he didn't chip any slag off. I thought you were supposed to. If this is an exception, then why?

[@SotraEngine4]

Maybe they simply didn't know how damaging it was back then? At this time fracture mechanics wasn't really a thing. Commersial electron microscopes wouldn't come for another ten years. Basically metallurgy was at its absolute infancy. They had only proven that metals were made of crystals a thirty years earlier, which is essential to properly understanding any metallurgy, really I mean, they didn't know that fatigue cracks even existed back then

They appear to be referring to "fleet-fillet welding" in the "incoherent" spot on the video at 7:31. You can find a description at delibra.bg.polsl.pl/Content/18436/P-779_1942_Vol110_No22.pdf The relevant pages are 70, 72, 100 & 101. These correspond to the numbering in the pdf file of 46, 48, 76 & 77 (hint: printing only those pages of document as a pdf produces a pdf that is easier to read than the original 33 MB document).
