Thank you so much for making this available! This is by far the best and most complete video course I've seen on this subject. I'm a few months into teaching myself how to weld with OA. I've watched and studied these 2 videos beginning to end maybe 15-20 times, and when I'm out practicing my welds, the voices of these two guys are in my head. I've really concentrated on mastering to the best of my ability the skills in the order presented, and it's paying off. The student/master Q and A thing dates back to Socrates, and is a classic, time proven way of presenting material in a logical fashion.
I wish this was the sort of approach taught in school when i was young. The back and forth counterpoints and visuals are fantastic for learning. Thanks for the upload.
Oxy-acetylene is great if you have a low budget, or limited access to power for stick/MIG/TIG. For example, it is used on farms for repairs in the field. It is slower, but gives you time to learn heat control, and manipulating the puddle. TIG is supposed to be super easy to pick up if you know OA (oxy-acetylene).
Wow, ... a big light bulb just went on in my brain. A new understanding on what I'm trying to accomplish when I'm welding. This is getting exciting, ....
again..Great basics video!! I have been welding for quite some time now...But pretty much like a do-ityourselfa kinda guy never enough to become proficient in it as I started out with an old 200-amp sears buzz box...and then doing some mig welding..which was great because it helps the welder so much in welding a good joint..whereas stick welding takes more concentration and coordination. It seems like 20 years now i have been saving up to buy a good professional mig set up LOL....but just when i'm going to take the plunge..there is always some other important bill to pay. because of the luxury of stick and mig...I never had much use for gas welding...so i do so little of it...a refresher is never a waste of time
I getting a torch , for my art mostly , the torch is more like the light saber of the jet I fighters. Also, I not have anywhere to plug into in the place I need to work , and not good dry surface to work on. Plus so many things can break on arch welders and plasma cutters , especially the lower cost machines. The oxyacetylene torch is more earthy and meditative.
Muy buen trabajo de filmación. Deja bien clara la técnica de soldadura en cada uno de los ejemplos. felicitaciones. Seria muy conveniente si alguien con conocimiento de idioma pudiera subtitularlo a español.
This is very knowledgeable video. And also explain very nicely. My question is when to use which welding method ( gas welding or ARC welding or MiG TIg).
Oxyacetylene soldier weld seems obsolete. Too . About like making a link that moves on a eye per say and the eye is worn down and needs to be welded . I don't see that on videos
No. Propane has different combustion properties, and doesn't generate a suitable reducing shielding gas envelope like oxyacetylene does. Even if the flame is fuel-rich it still ends up being too oxidizing for welding. If you try welding with oxy-propane you will get a good sparkler show and a porous weld.
Not with welding, but with brazing, which uses a different metal + flux, at below 800 degrees C. Brazing can be nearly as strong as welding (60-70,000 PSI) but the flux coated (usually brass) rods are more expensive than steel filler rod.
After all those annoying, redundant questions, the one single question I had that did NOT get asked: What would be the effect if that 1/16" spacer wire were to be omitted in fitting up the butt weld of the sheet? ...i.e. if the two pieces were to be butted tightly together.
the metal needs to be able to expand as it heats up. so if the two pieces are touching, they have nowhere to expand and you'd end up with a lot of distortion instead of a nice flat weld. this is far more of a risk on thinner material.

You dont get enough penetration because the molten metal does not get to the bottom. You would need to heat it much more with will get you other problems like defromations or undercut.

Great video!! This should be an example of how to make great instructional videos.

great welding video. gets right to the point. shows great technique and clear photography. also love the computer music.
Very good lesson. Thank you guys so much from all side of knowledge. Hope you can share more information.
Oxyacetylene welding should still be learned . No matter how much technology in welding progress. . Just saying.
Awesome vids thanks for posting. Us gas welders are a class above the plastic welders.
Really good video. The guy was asking all the right questions for the beginner.
Good stuff. Learned how to gas weld in high school during the 70's, just started to again. Pretty rusty but getting better.
Great video, demonstration and instruction!!!!

"Watch him closely here as he finishes the weld..."
...immediate fade to end the clip.
Sigh.

very good work and video
In Sweden the Colleges still teach you to weld with oxy acetylen
Very few even teach that anymore. One can weld with no filler rod it depends.
Proof that clothes don’t make the man, results do.
Right? I don’t think I’ve ever seen some weld wearing a tie before!

A lever point of movement that it's moves on . I call it the eye fer some crazy reason.
There is one more that goes earlier than oxyacetylene welding. But that a different one.
It's not taught anymore
Lmao thatchew.
is it possibel to get the same quality of weld using propane gas instead
Yes, but the oxy-propane does not get as hot so it might be a little slower than Oxy-acetylene
No. Propane has different combustion properties, and doesn't generate a suitable reducing shielding gas envelope like oxyacetylene does. Even if the flame is fuel-rich it still ends up being too oxidizing for welding. If you try welding with oxy-propane you will get a good sparkler show and a porous weld.

He did answer that by telling you that you won't get full penetration of the weld. You may get 80% or 90%, but it will fail inspection.

insufficient penetration. you want a weld to be all the way through the material
