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.
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.
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.
In Scotland they still teach us Industrial/Commercial heating engineers it along with stick. Then a 6G trade test on both & they set your free with a "provisional welding licence" 😂😂 not coded tho. Never once used gas welding but now I'm doing mechanical maintenance I stick weld all the time & looking to go for my coding pretty son. That's the next goal anyway
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.
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.
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
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.
It is cheaper to get up and running with but gas ads up pretty quickly. To fill these two little bottles it cost around $50 where a 80 tank of 75/25 or 100% Argon costs around $30 to refill. The upfront cost of MIG or TIG is higher but in the long run might offset.
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.
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
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 RUclips 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?
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 *
Learning Stick first is what most people say to do because it teaches you a lot without needing the gas, tungsten, and at the parts that makeup a tig torch. But if you want to dive into TIG it might be a bit of a learning curve but with practice you can get any process down.
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. 🙏
We would have to do a deep dive on that because using different types of flames can add different properties but we have a great podcast talking in depth on Oxyfuel in the description above.
You can get distortion with any process but people tend to move too slow with TIG and Oxyfuel causing more distortion from the heat. Clamps are a man’s best friend.
Hi i Have a question about oxyao but backfeeding i just finished my welding license And was the only one in class to dare try backfeeding on the final exam And i succeded Its just that i spent Hours learning it by myself bcs my teacher neither the examiner Said that they can do it and had no tips for me to try especialy the pipes was all my primal instincts i first tried vertical Pipe position, horizontal i spent around a day learning but probably my biggest acomplishment was my first try on 45° with perfect root pass (yes i am ambidextrous) still i dont know if im doing it right do you have any good source where i can go and watch or maybe one of your older videos where you show the correct procedure especialy the pipe ones. When the examiner told me He has no idea i was kinda put down by it And asking myself if i just spent Hours perfecting something that Is useless. Also i Have no welder in my family And have no pre license experience with welding.
You are correct, but as far as common use in the industry this one fell out of favor over the years compared to other processes. OA Welding start around 1902.

I’m glad this helped you out! I’ll make sure to add those topics to the future videos.

Sounds like you have a lot of experience with OA welding. It's definitely a useful skill.

Really great for teaching how to control your heat for sure!
I really want to learn OA more. I will be checking out the other vids for sure 🔥🔥
We will keep them coming
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.
Definitely a fun way to weld!
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
That doesn’t sound like fun at all

It will always he cheaper than tig or mig if you're good enough considering how high electricity is these days.

The Henrob is an injector type torch.
Saving gas is a pretty big deal in the long run.

Definitely will have to give that a try!
thanks, this helped

Why is that?
That's a great question! The heat from the flame displaces the surrounding air which is doing the same function as the shielding gas.
I do that almost everyday. My filler is rg60. Dude is running very hot for 16ga.

In the UK the one line has left handed thread fittings.
That is very common over here as well.
It’s easy to get heat distortion issues with TIG welding. I can’t imagine how bad the distortion can be with this welding process.
You can get distortion with any process but people tend to move too slow with TIG and Oxyfuel causing more distortion from the heat. Clamps are a man’s best friend.
ah just what im looking into for fun
It is a pretty satisfying process indeed
3100 C x 9/5 +32 = 5612 F
There it is thank you sir!
Hi i Have a question about oxyao but backfeeding i just finished my welding license And was the only one in class to dare try backfeeding on the final exam And i succeded Its just that i spent Hours learning it by myself bcs my teacher neither the examiner Said that they can do it and had no tips for me to try especialy the pipes was all my primal instincts i first tried vertical Pipe position, horizontal i spent around a day learning but probably my biggest acomplishment was my first try on 45° with perfect root pass (yes i am ambidextrous) still i dont know if im doing it right do you have any good source where i can go and watch or maybe one of your older videos where you show the correct procedure especialy the pipe ones.

miss that ol man cub ... hope he's doing well
We miss him too and hope the same!
Can I just melt the plate and push my puddle?
You can do that as well but adding filler helps control your puddle by cooling it down.
You will almost always blow through if you dont use filler
I tried to learn this in High School shop class. All I managed to do was set my hair on fire with the filler rod end! Way harder than TIG!
Always worth giving it another try one day.
It’s 5,621 degrees Fahrenheit
The combustion gas shields the puddle.
If open both you don't have that black smoke 😮
Indeed the oxygen will help consume the carbon in the soot, but was just taught to start with fuel to light your flame before introducing the oxygen.
The temp is approximately 6,000° F
Arc Welding is older
You are correct, but as far as common use in the industry this one fell out of favor over the years compared to other processes. OA Welding start around 1902.
