- Native resolution is 480p (720x480 pixels); actual movie size is 640x480 VGA. Closed Captioning done by me.
A late 1940s-ish (some sources say late 1960s) production that involved Disney and Lincoln Electric which demonstrates the properties of distortion and methods for reducing its undesirable effects, along with a Mr. Shrink character to personify the principles of distortion.
Dumped from a VHS tape, then to a DVD for awhile, which was then dumped and crunched with Handbrake into AVC (.MP4, H.264) at approximately 1500Kbps and audio at 160Kbps. Note that this video comes from an "ancient" method of media (pre-dates VHS!) and as such, imperfections are the nature of this work. The video footage also suffers from blooming and other artifacts beyond my control. Other sources may have better quality footage but are not complete or as publicly accessible.
Fleet-Fillet welding mentioned at 07:33 is a technique whereby welding arc current is increased (and using different electrodes) along with travel speed, along with a change in traditional angle of the electrode. Details of this can be found here: A) delibra.bg.polsl.pl/Content/1... B) web.archive.org/web/202109142... C) Message me for a copy. Relevant pages are (real pages not PDF pages) PG 70, 72, 100 and 101. Thanks to August Pamplona for this reference.

I spent two days manually close-captioning the whole thing. I tried to attach the .srt SubRip caption file to the movie but Handbrake wasn't doing it right, so I let TH-cam take care of the .srt file.

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.
too funny
its true they keep his head preserved in a vault and force him to narrate instructional videos lol.
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.
@Bodie Maxwell instablaster :)
Because it is.
Nothing like old instructional videos, they always explain things best.
It was a film.
You are all right
Agreed, the little shrink cartoon has very good visual explanation too. Great education film
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
That said, it did omit things that are extremely important which would be dicovered around 20 years later
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.
This video is actually pretty good for being 75 year old. Explains better than a lot of TH-cam videos.
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.
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
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.
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.
Im about the same age and we had tvs on rolling carts, what's that got to do with anything bro?
the release date for this video was12 april
1945, i love this kind of videos,they teach in an easy and funny way
+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!
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.
Video by WW II 😂
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.
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.
Back-stepping... Brilliant!
Nothing makes a class of adult women and men break the serious air of a learning environment faster than a personified Shrink falling on their ass.
Even today These Old instructional videos are still the best at explaining things
If you have the skill to use Rule 2, friend you are a master fabricator.
Good old basic instruction from a generation that got work done quickly and accurately
I think our whole shop needs to watch this, and many more like it. The more we know, the better we will be
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!
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.
This may be old, but it's still valid and very very informative.
Good information is ageless. I'll still watch this over the newer vids.
OLD SCHOOL IS THE BEST SCHOOL!
Best explanation ever regarding welding distortion. perfect. never expected that Disney will ever produce a content related to academic or engineering purpose.
They did hundreds of this type of video for many industries, it was a very lucrative part of the business.
Got a project to do where I suspect warpage will be a factor. This is exactly what I was looking for. Perfect, thanks!!
Great!!!!!! So many videos about shrinkage...but old one explains the best!
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?
It was so interesting. Thanks for saving this video for broader audience
Thanks for sharing the basics. Too many people overlook these basics.
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!
awesome video. I've not seen a more clearly explained vid on welding shrinkage, thanks!
It's a superb video to understand the distortion of the weld.
Great video. Made me understand distortion a lot better now.
they showed us this for orientation while making boilers for cleaver brooks. great video
i love these old videos they make way more since then all the scientific explanations. theirs alot more of these videos on youtube too
My metals teacher assigned this as an homework video lmao, was great
George: I had shrinkage Jerry!!!
One of the best Videos. Best one before exam ;)
I love this old instructional video!!
I like to say this is very very good video of how to learn welding
thank you for all your effort
Very good explanation!!!! Tanks by the post!!!!
Still works the same after so many years.. very practical physics
mejor explicado no puede ser!!! gracias por el video!
Excellent explaination
Mr. Shrink still gets his revenge in cold weather or whenever you go to the pool.
Great video still used by many educators!
What a gem
nice video with good examples
No way this is the 60s!!! DEFINATELY 40S!!!!
That's cool, I like what you did there ;)
Great video!
Nice video!!!
thank you very much !
Awesome and thank you for posting this! Do you have any more?
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
Mr. Shrink sure can be helpful!
Thank you so much!!
(the music and pictures are so funny !)
This is what made America great!
Funny educative video! :)
Thank you
thank you!😀
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.
MetaIIica93 What does left to right or left to right have to do with penetration?
+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.
+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.
MetaIIica93
What moron told you right to left gets better penetration? LOL Morons...
MetaIIica93 your awesome keep it up.
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...
Ha remember watching this in college 5 years ago :)
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
The laws of physics haven't changed in the past 70 years.
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
do you have any more videos ? thats was cool thanks !
This video didn't help me in any practical way but I was very amused watching it.
great
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...
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.
Unfortunately a lot of the Liberty ships split in two due to insufficient knowledge about how cracks behaves
Ha! Awesome
Old video but is good.
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?
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.

as good today as it was then ,,, you canna change the laws of physics , captain ,,, as a well known scotts engineer has been heard to say.
+tom thompson I miss that show. Amazing how much can be learned from this video even when using a powertig welder circa 2016!
ok thank you
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.
Mctc college uses this video for class
There was shrinkage!!
Please explain as if you were to a child, always works for me. I suppose there's no shortcut then.
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?
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
@@SotraEngine4 thanks for answering my question. Makes sense.
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).
Thank you for the reply. I will update the description and subtitles now to reference this properly.
How did I get here?
my metal plate is warped today after welding, so I see it
Got some inaccuracies here
Top Ten Anime Villains
Those metal welding helmets must have weigh 10 pounds. imagine wearing that 12 hours a day.
Well, fuck me! This is as funny, as usefull!
من هم این مشکل بزرگ را دارم و نمیتوانم مشکل را حل کنم متاسفانه زبان انگلیسی بلد نیستم تا از ویدیوی استفاده کنم
This might help Ryan R.
This video really be the #1 hater of mr. Shrink, what did he do? He can’t help who he is.

"Too bad it is not like that any more..."
It is too bad and sad as you can see the results of what was Detroit via the outsourcing and offshoring of our jobs and plants because the Americans citizens voted for the GOP-Dem Corporate cabal whom in very bipartisan cooperation sold our jobs to non-Americans....Americans can have all sorts of reasons and excuses on why they did that but the fact is America doesn't want real jobs or a job at all....Sad but true.....
+DFAULTPOSITION not all dems nafta was a clinton effort
soooooooooooooooooooo slow
