Question - Do you think that welding students should have to learn to oxyfuel weld first?

I recently had an implanted cardio defibrillator put in. I was told that I shouldn't use any type of electric arc welding. I am having to relearn oxy-gas welding. This video has been extremely helpful and I would love to see more detailed info on welding the thickest and thinest metals, welding cast iron, etc. These types of videos are literally life changing for those that have had this surgery.

Right on man! I'm in the Navy and we still teach Oxy/Acetylene welding. Reason is on a ship, if you take any damage and the power goes out, you're still able to weld and make necessary repairs. In my trade, we teach this method before moving to stick, MIG and TIG.

[VTdarkangel]

I taught myself OA welding a few years ago. For me, it was a matter of practicality. I do commercial refrigeration work, so I always have a torch rig with me. I have run into problems where being able to weld something together would be best solution. Unfortunately, at the time welders were very heavy, and as such weren't practical to keep in an enclosed service truck, and I didn't have the space for an engine drive welder. The inverters had just started to come out and were extremely expensive. So, as an alternative, I decided to learn OA welding. I mostly used it to make L-brackets out of strut or angle iron. It ended up being a useful skill to have in my back pocket. As a side effect, it also made me a better pipe brazer because it made me get much better at working a torch and reading temperature.

I taught myself how to oxy weld when I was 14yo back in the 70's so I could build and weld expansion chambers. No mentor, no books, no youtube so I could weld expansion chambers for motor cycles, used coat hanger wire as filler rod. When I started my apprenticeship I was the gun. I haven't oxy welded in decades but it put me in good stead to teach myself how to tig weld, It's a very similar process.

When I learned OA welding 60 years ago, I was taught to begin with a very small amount of oxygen. Then some acetylene. Not to get that black smoke when igniting.
Angle of the flame important to heat relation between working pieces and filler. Did a lot of repairs on rusty old cars in the sixties. Having a reducing flame pointing almost parallel to the sheet metal, you can weld rusty paper thin sheets. Frequent stops to cool off. Angle also important joining different thickness materials.
Was taught when job finished, close valves on cylinders. Later check manometers. If pressure has fallen, you have a leak. Then open torch valves to release pressure.
The real problem ( and danger ) is all that heat around the flame.

I learned how to torch weld before any other welding. It is by far the most diverse form of welding and can be used for almost any application if you have the skill. Its the hardest form of welding and therefor made learning everything else that much easier when the time came.

[mikewithers]

I really want to learn OA more. I will be checking out the other vids for sure 🔥🔥

[JonasDecker-zx]

Had to learn it in basic training. Burned the hell out of my wrist with glowing filler wire . Friend of mine managed to burn that rod in next to his nose

[lajoswinkler]

It's the hardest way and the best way to learn, but when you learn it, you can produce extremely high quality welds. With MIG and stick people often do sloppy work because it's easy to make it sloppy. Oxyacetylene forces you to do it properly. It's also extremely versatile, can heat steel for bending, melting. With proper small torch, it is perfect for welding lead (caution, fumes!), too.

[beyondmiddleagedman]

I GTAW, GMAW, SMAW, resistance and OA weld. OA is my favorite. Slow, but relaxing.
If I could only have one process it would be OA as I can also cut and heat with it.

[brick]

I learned this when i was a kid i used a coat hanger and welded up holes on my welding table. Its a fun way to weld.

[Sireal_beats]

Damn that’s like 5, 612 degrees Fahrenheit 🥵🔥

[BobVan]

Picked up one of those old Henrob pistol shaped torch’s a few years back. You’d think it would be easier to hold and use but I still think conventional torches feel better in hand. The henrob uses less gas though.

[dennislillywhite]

I found that if you spread your pieces apart about the width of the filler rod then it helps to make that keyhole maybe a little close depending on the pieces you are welding I understand that isn’t precise but if your using this method your most likely just trying to get it fixed not to worried about precision

[renaissanceman]

Been working on a project lately and a couple of days ago wanted to continue. Wouldn't you know it, just as I was about to start welding the power went out. I had never used O/A to weld before but after watching a couple of YouTube videos I gave it a try. I like it. In some ways it's much easier than other processes. I do find it odd that every other process requires shielding of some kind but O/A does not.

Why is that?

[KevAF_]

i find it easier to light my torches from the lit cigarette hanging out of my mouth. lol

[tedbastwock]

Is it cheaper to operate than TIG or MIG? There are good reasons to have this in ones arsenal. Thanks very much for this video.


Cheaper initial cost to get started compared to any arc welding when considering AL and thickness (I think, I could be wrong)
Can be used remotely, i.e. away from a 240v outlet
Can be used right next to a 240v outlet when that outlet has no power
Its a multiprocess tool since we can cut with it too
With the lack of electronics and moving parts, I'm guessing it has a longer useable lifespan .. please correct me if I'm wrong.

In the UK the one line has left handed thread fittings.

[lawv.]

Good stuff. Newer subscriber.
Really wanting to learn how to weld, was going to get a Lincoln tombstone ac/dc arc but I'm torn to going that route or just getting a tig set up from harbor freight just to get started.
Eventually want to tig weld but want proper practice and a learning curve so to speak.
Appreciate any feedback and keep Rocking *

[Dr.CandanEsin]

Is the hardness and structure of metal change after welding compared to mig/tig welding? Thank you very much for this simple and encouraging informational video. 🙏
