I love these videos. Whether you're machining, welding, or fabricating, the information is just as relevant today as it was all those years ago. I have been greatly helped in my own shop, watching these videos. 👍
Son you learn how to weld and cut with Oxy Acetylene FIRST. It will help you when you are learning the newer - and harder to understand - welding processes.
I went to aircraft welding school. All the airframe stuff was oxy-acetylene welded. Worked on British sports cars; those aluminum sheet bodies were torch-welded too! I used this technology to repair cars; sheet metal, cast iron and fastener work.
I was a brand new apprentice when my Journeyman caught me tightening the O2 and acetylene gauges with a pair of Channel Locks. I think my ears were bleeding.
I'm really fortunate to have been one of last generation to have these old school welders as teachers, my shop teacher in high school was amazingly skilled and taught me how to weld and braze with Oxy/Acetylene, along with stick welding, TIG welding, MIG welding, and last but not least, friction welding, I was really fortunate to get that kind of education considering what state the education system is in now, there's no longer any focus on those types of skills in high schools now and it sucks for the younger generations. Oxy/Acetylene was one of my favorites, I loved brazing and welding and making coffee cans shoot holes in the ceiling insulation after sitting then upside down and filling them with gas from a tapped out nuetral flame, and then lighting them😂. I got a stern look from the teacher on that one, but he was trying to hide a grin too so... 🤣
@@elfpimp1 it's pretty badass, it involves two pieces of metal that are spun against each other to create so much friction as to melt the metal together, and there is also friction stir welding for aluminum and some other metals, which involves a special tool that literally "stirs" the metal together under so much force that it plasticizes together. The weld is stronger than the billet metal around it, one engineer I worked with (making a friction stir welder for Boeing) did an explosive test on two plates welded together, and the only thing left after the C4 went off was the weld, a big long strip of it. You should UA-cam it, it's pretty impressive to watch.
Where have you been? Techniques like submerged arc and tig have become the gold standard for most steels. The last time I saw new riveted beams or joints is the early 60's.
@@lowercherty Here in Houston TX there are a lot of new construction steel beam bridges. They are loaded with rivets. Rivets can take the constant flexing and the heating-cooling expansion of the beam where a weld could form a crack and fail.
They don't even roll large beams over about 16 inches anymore. They submerged arc weld them from plate and strip. The rivets in new construction in Houston must be a local thing. You sure they aren't bolts?
Where was Joel and the bots? Dr forester and tvs frank???? Truly an art form, I took welding 2yrs at vo-tech ( vocational/ technology) in highschool. Jr Sr yrs 3 hours a day Went and competed in the skill Olympic both yrs..sold programs to the phx jc of jaycee rodeo of rodeos to earn money for competing. 1984-85 Highschool punkrock kid selling rodeo programs haha
I'll admit I live in a car now. Sometimes its hard to get food let alone an education. Does it cost a whole lot to go to welder school and does it take alonge time? Times are tough can a living be made?
The oxygen bottle should always be opened all the way. It has a rubber seal on each end of the valve to stop leaks while welding. I'm suprised they didn't mention that.
In the late forties the valves had a design change. In the old design. The valves you describe are of the old design. The newer design uses a diaphragm to seal the valve stem thereby not allowing leakage in any position. A quarter turn of the valve is usually sufficient for most welding, and is much quicker to turn off in the case of an emergency.
@@paulhagerty2773 any high pressure has a double seating valve, and should be opened fully. You open the fuel gas valve 1/4 turn so it can be closed quickly if a hose ruptures.
I seen the first mistake NEVER EVER use a wrench to tighten the nut attaching the welding nozzle to the hadle the nozzle has 2 "O" rings on the mixing chamber and yanking on it will damage the rings causing a fuel leak and possibly a fire, HAND tighten the nut only same goes for the cutting attachment and heating nozzle.
Unfortunately I've never had any formal training but as a kid teaching myself to braze it only took 1 or 2 loud POPs to learn to cut the O2 first then the C2H2.
In high school welding class, we had to learn this second so we would know how metal/steel flowed. First was brazing to teach us about 'tinning' metal. Then we moved on to A/C tombstone welders. 6011 for welding up farmer Brown's corn chopper. Only then would they let us use the 'fancy' MIG welder, which I have called the 'glue gun' for metal. Would like to see how my OXY/Acetylene skills transfer to TIG. Seems like the heat control pedal would make it easier to control. Probably just fooling myself though.
I have always considered TIG to use the same techniques as oxy. The flame is substituted for an arc, but everything else is same, especially when you don't have a pedal.
The shop class in my school was the same way. We had to butt well two pieces of 1/4 plate steel and the shop teacher would put it in a vise and grab it with a pipe wrench. If he couldn't break it you got to use the mig welder. I cheated though, I snuck over to the mig welder, ran a bead between the metal and then went over to the stick welder and went over it to hide the mig bead. He couldn't break it lol
Schooling has changed over the years. It is known, that if you light the acetylene on it's own, it will fill your environment with harmful carbon. Always add a little oxygen before striking the flame, to assure that this carbon is properly burned off.
This was NO, NO, no no no when I was trained to weld as plummer. If someone opened acetylene and ignited the torch without oxygen the teacher freaked out. Every time I see someone do that I remember blessed Jan : ''It's a difference between a plumber and a KLÆDDSMED (meaning a really coarse/bad smith) It's really NO need to fill the workshop with soot doing it that way!!!!!!! Jan was old school and I remember very well he shouted to one student: If I were able to, I would beat you up'' :-) Best teacher ever !
And now in today's welding trade schools they do not introduce torch welding. Only cutting. And now you have to enter a training course that uses this process. So today's welders wouldn't know how to do this
This is taught in Aviation Mechanic Schools. Why? Well electric welding on an aircraft full of delicate compasses and flux gates could kill a bunch of people !
Trust in The Lord God Almighty for He is good and His mecry endoreth for all genarations be blessed forever un the name Jesus amen in the name of the Lord Jesus Christ Amen.
I will never forget my first bead ,excellent video ,left-handed threads on the acetylene torch
What a pleasure it is to watch complicated things being explained in a simple manner
"tough guys burn just as easily as sissies"
A completely different age. I love it.
Burns don't discriminate.

That caught my ear, too. We could use a little more plain speaking today.

Hello! I am 19 and am learning how to weld. I'm not too great yet, but I live this industry!!
Learn TIG. Much more in demand than acetylene welding.
Son you learn how to weld and cut with Oxy Acetylene FIRST. It will help you when you are learning the newer - and harder to understand - welding processes.
O.A. welding is a gateway to tig.
@@grumpycricket Sort of. Oxy-acetylene is a lot more portable, that's for sure! But with the new mini gas driven welders that is changing!
I learned how to torch weld in high school in ag class. bout 10 years ago . it was fun !
My dad worked as a boiler maker he taught me how to acetylene weld I could put a bead look just as good as tig
That's not really that big of a brag
@@radioanon4535 I guess you right but it was 50yrs ago

That was so cool ..neat to look back at these training videos ..from so many industries thank you for sharing
welding is so satisfying
skyeye051. that's how I feel about drugs
It's better than drugs. And more addictive and expensive.
Thank for the very good video.
I was a brand new apprentice when my Journeyman caught me tightening the O2 and acetylene gauges with a pair of Channel Locks. I think my ears were bleeding.
That's a worse screaming than using an adjustable wrench
Those poor chewed up brass fittings lol
My pop was a pipe fitter and taught us at a very young age how to gas weld.
Acetylene fittings have been left-hand thread as long as I can remember.
This is how I learned to weld.🙂
This was great, thanks, I'm just trying to get into this with a small hobby torch kit and I think I picked up some great basic pointers!
Glad it was helpful! Subscribe and consider becoming a channel member ua-cam.com/video/ODBW3pVahUE/v-deo.html
This a great starter. Once you have the proper basic mechanics down, it's just practice and more experience.
Tip of the torch pointed "sidewise".... I like that.

Friction welding?? I'm intrigued 🤔! Yes I could "Google it " but I like engaging with live folks..

I never couldn't get past the POP when you turned it off, I didn't want to get blown up.
Turning off the wrong one first. Too stoned to remember.
@@tacomas9602 I require my guys to turn off the gas before the O2. There is a pop.
@@bingosunnoon9341 you own guys? Wherever you are. Id walk off. Its Oxygen first and youre presenting a safety issue trying to tell me what to do.
Ahh that was like meditation or man yoga
"keep the acetylene away from fire or you may finish this course where welders don't need blow torches." 😀
This is a educational episode of welding in the 1950s if you are become a welder now you can make a lot of money it is a lost art
All trades are becoming a lost art. Kids only aspire to be UA-cam stars or social justice warriors anymore.
how on earth is welding a "lost art"?
@@davidannett3322 😂😂lol right dudes smoking crack
Are we not going to talk about the narrator gaslighting the entire audience at 10:20 ? Lol
When this catches on a lot of riveting gangs will be out of work...
Rivets are more reliable than welding which is why they are used in critical areas like aircraft, bridge beams, skyscraper beams, steam boilers.

Nice
What's the oldest inspection stamp that you have ever seen? I've seen a 1936 and one from WWII with a swastika on it but it was crossed out.
That is cool
I was in an old powerplant about 10 years ago. They were showing me pipe elbows with swastikas on them. Was very cool.
I was looking at a CO2 bottle the other day and it was a converted oxygen bottle. 1928.
stackin dimes since 1950
I'll admit I live in a car now. Sometimes its hard to get food let alone an education. Does it cost a whole lot to go to welder school and does it take alonge time? Times are tough can a living be made?

Welding is #Art. - #Sculpture
Art welding isn't real welding
Used it a LOT till I got my TIG setup!
I seen the first mistake NEVER EVER use a wrench to tighten the nut attaching the welding nozzle to the hadle the nozzle has 2 "O" rings on the mixing chamber and yanking on it will damage the rings causing a fuel leak and possibly a fire, HAND tighten the nut only same goes for the cutting attachment and heating nozzle.
We were taught to shut off the oxygen first, THEN the acetylene. IIRC the reason was to avoid internal fires down the welding hose.
Reminds me of that "O before A..." saying
Oxygen shouldn't cause any internal fires, it is not flammable. Acetylene is, and can cause backfires.
Unfortunately I've never had any formal training but as a kid teaching myself to braze it only took 1 or 2 loud POPs to learn to cut the O2 first then the C2H2.
Oxygen does not burn. Shut off the fuel at the bottle first. That's the way I learned it in college.
Liar!

No one way valves and no flame arrestors on torch handle or regulators. No wonder there were many flashback accidents.
Show a cutting torch washing a weld.
Guy empties both tanks blowing everything out, lights the torch and he's out of gas. lol
FFS, NOBODY sets up like that. Never.
Well how do you set up? Do you not purge the cylinders and lines? I think this was just done slowly to demonstrate everything clearly.
Я не понял, чём он зажёг гарелку?

And they teach it exactly the same now as they did then. Nothing has really changed, to my knowledge.
did people talk like this, like, everyday everywhere back then?
No. All these films were done in a corny way. Go back a couple of decades and they were rolling their Rs. So crazy.
