This black and white vocational training film (with opening titles missing) aims to prepare beginner welders for safe and efficient handling of oxyacetylene torches with an educational tour of oxy-fuel welding techniques (TRT: 18:06).
A man dons goggles and tests an ignited oxyacetylene torch. Narration: “Engineers are placing more and more confidence in this method of joining metals together” (0:06). A torch welder repairs a piece of damaged metal. A blowtorch and filler rod in closeup. A group of two welders working in tandem. One wears a blast shield. “Metal welding is not just another trade, it is an art” (0:25). Tools of the trade sit upon a bench, laid out for easy viewing (1:21). A welder in a protective coverall suit, cap, googles, boots, and gloves fades into view. “Never do welding of any kind without goggles” (1:39). Setting up equipment and turning on gas tanks: Cracking cylinder valves to clear clogged dirt. Attaching nozzles and attaching hose lines to the regulator dials. Red is paired to acetylene, and green is paired to oxygen (2:26). Opening the cylinder valve slowly and adjusting the regulator screws (3:37). Connecting the hose to the torch and blowing out valves (4:28). Adjusting the regulators to match pressure (5:10). Lighting the torch with a spark lighter. Narration: “Tough guys burn just as easily as sissies” (5:34). A closeup of the torch’s flame as it is adjusted, with text indicating an “inner cone” and “envelope flame.” The “neutral” luminous cone melts a sheet of steel. A greater ratio of acetylene extends the flame’s envelope and boils metal (6:04). An oxidizing flame gives off sparks. A harsh flame creates a mess, a more controlled flame’s eye does better work (7:38). A flame is calibrated. As the valve closes, a neutral flame is formed (8:45). Setting up a welding table and lighting the torch (9:10). Calibrating the flame. Proper handling of the torch. “If a job is too tough and tiring, chances are you’re not doing it right” (9:40). The torche’s cone tip approaches steel. A puddle of molten steel forms and the torch is moved across the steel in small semicircles (10:45). The torch is raised at the end of the metal sheet. An example of steel ripples after a practice session (12:02). Beading is demonstrated. A straight welding rod is melted to a right angle. The welding rod is brought to a near liquid point, then deposited on the sheet of steel as the torch heats both surfaces (12:34). An improper splattering technique is demonstrated (14:03). Sparks fly. The welding rod sticks to the sheet, then is loosened (14:42). Proper technique is reviewed in closeup (15:10). Examples of good and bad beading results are compared and contrasted. A bad example shows holes and inconsistency. An underheated weld shows lumpiness (15:25). Quitting time. Closing valves, draining both torch lines (16:22). A closeup on the torch nozzle as it is cleaned with soft metal. Hanging up the torch and removing protective gear (17:14).

When this catches on a lot of riveting gangs will be out of work...

[@glasslinger]

Rivets are more reliable than welding which is why they are used in critical areas like aircraft, bridge beams, skyscraper beams, steam boilers.

[@lowercherty]

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.

[@glasslinger]

@@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.

[@lowercherty]

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?

I learned how to torch weld in high school in ag class. bout 10 years ago . it was fun !

[@coonhoundqueen9216]

That was so cool ..neat to look back at these training videos ..from so many industries thank you for sharing

[@TheExplosiveGuy]

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]

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

[@TheExplosiveGuy]

@@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 KZbin it, it's pretty impressive to watch.

[@grumpycricket]

This is how I learned to weld.🙂

[@bingosunnoon9341]

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.

[@paulhagerty2773]

Wrong.....

[@paulhagerty2773]

Dangerously wrong One quarter of a turn or so.

[@tracylemme1375]

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.

[@TozziWelding]

@@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.

[@chrisbeard5794]

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.

[@NipkowDisk]

We were taught to shut off the oxygen first, THEN the acetylene. IIRC the reason was to avoid internal fires down the welding hose.

[@anthonycarlisle6184]

Reminds me of that "O before A..." saying

[@Taxvs_]

Oxygen shouldn't cause any internal fires, it is not flammable. Acetylene is, and can cause backfires.

[@n6mz]

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.

[@bingosunnoon9341]

Oxygen does not burn. Shut off the fuel at the bottle first. That's the way I learned it in college.

[@MichaelKingsfordGray]

Liar!

[@BigDadio1967]

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.

[@firebird77clonefirebird89]

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.

[@mshort7087]

Tig is so smooth. You’ll love it for benchtop projects

[@who_cares848]

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

[@chriscusick6890]

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?

[@AlphaFlight]

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

[@zsdfgzxdcfg5203]

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 !

[@badcat2922]

Я не понял, чём он зажёг гарелку?

[@TroyMcBride]

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.
