Welding: Oxygen Acetylene - Kevin Caron

[morgorth3242]

also that you keep the ogyxA at a angle to pre heat the metal ur welding

[kevincaron]

@morgorth3242 yes, that helps with the thicker metal. Anything over about 1/8 inch and you should start to preheat the metal as you go. Angling the torch forward is a great way to do it.

Thanks for posting..

[morgorth3242]

i have learnd that you should tag weld first the 2 end before you do the hole weld is that correct?

[kevincaron]

@morgorth3242 That is the best way of making sure your metal stays where you want it. I do it also, with any type of welding.

[megazwan]

do we can actually use coat hanger metal instead of proper filler rod?

[kevincaron]

@megazwan I have used coat hangers for years!! Just keep in mind that I was working on exhaust pipe or fence posts. I am not saying to use coat hangers for building bridges or airplanes or such. Coat hangers are a VERY soft metal that works very well for non critical welds. It allows for a certain amount of flex in the weld before it cracks. Keep in mind also that I am NOT a certified welder and have no formal schooling. This is just what I have learned over the years.

[tdematteo01]

Nice job Kevin.

[kevincaron]

@tdematteo01 Thanks.

Always like a pat on the back instead of a kick in the butt..

[hotrodz2hell]

Hey, haters are gonna hate. Most people who run their mouths do so because they don't have any skills to use in their argument... just words. ;)

I AM a code certified welder. D1.1, D1.5, and D15.1 code. Also do a lot of ornamental TIG for hand rails, grab rails, etc. in stainless, titanium, aluminum....

Keep up the good work. Like you said, for a guy who is just doing art or something at home and just needs to get it done, you're doing fine. You don't need to know "terms". :thumbup"

[kevincaron]

@hotrodz2hell Thanks! Always nice to get a pat on the back from a Pro. Sure would love to get you in the studio for some tips and tricks.

Stop by anytime.....

[tinydog6666]

Thanks for the video. I went out and got a welding tip for my torch so I can try it.

[sshay0100]

for all the folks who build bridges or work at steel shops and make a living by welding, this video would probably drive them silly, but for the guy who is working on home projects, this is great. thanks for the video

[kevincaron]

.@sshay0100 . I would hope the people who do this for a living are not coming to YouTube to further their education.

On the other side, thank you for the kind words..

[walterbrunswick]

This man is ignorant. There are SO MANY things he's done wrong! BAD TECHNIQUE!!!!

[kevincaron]

@walterbrunswick We are all looking forward to your video of the correct way!

[walterbrunswick]

@kevincaron I'm in welding class this semester. Aside from the professor, I was showing some of the students how to set up the regulators and torch properly.

Once I buy some welding equipment of my own, I will demonstrate the proper technique, terminology, and theory.

[marineplatoon1]

i understand that corner welds are hard but i can do ten times better and im 18 ive only been doing oxyfuel for a year off and on and i got first at state for my welds so i think i can say that yours arent as great as everyone is saying

[kevincaron]

@marineplatoon1 I am sure we all would love to see your work. Where is your website??

[marineplatoon1]

@kevincaron i dont have one but ill upload some pictures to facebook and ill give links

[fabe202]

Great video Kevin! Very clear and concise in your presentation.

[adammcmillen1]

i very much enjoy your videos. very informative. i'm fairly ignorant to the subject and i was wondering if one can weld stainless steel with this process.

[kevincaron]

@adammcmillen1 You can but you will not like the results.

[Nanovirus5995]

Thanks. That was nice simple video. Short and sweet ^)^ I liked it!

I have a question, I am thinking about synthesizing my own Ruby's and I need to reach temperatures in excess of 2100'C. From my understanding, the torch already reaches around 3300'C which is plenty hot enough. However, would it be hot enough (or large enough flame) to melt a volume of nutrient (powdered chemicals) about the size of a small cup?

[kevincaron]

@Nanovirus5995 You should look for a number "8" rosebud tip. Make sure your regulators are set correctly and you should have plenty of heat to do what you want. Maybe get some fire bricks and make an enclosure to trap the heat and focus it on your cup.

Would love to see a photos or two when you are done.

Thanks for posting.

[rodger2k11]

Instead of using magnets, why don't you use bricks instead?

[kevincaron]

@rodger2k11 Because the bricks won't hold the metal together until I can tack weld it. I just forgot to take the magnets out for the rest of the welding.

[jkmcflaren14]

@rcfreak2493 I wouldn't recommend buying a portable torch set because since acetylene is so volatile it's tank needs to be mixed with acetone and some sort of sodium chloride because it explodes beyond 15psi, so he smaller the tank; the more pressure and the more it cost to fill that small tank you're not going o get much use out of, so you'd be better off with a medium duty set and tanks

[nealart]

Thanks.

[SKRussSK]

great video tutorials thank you

[949dk]

isn't this also called brazing or something like that?

[kevincaron]

@949dk Brazing is very similar to this but you use different filler rod and flux.

[949dk]

@kevincaron oh ok cool

[devilkin9001]

You don't even need to add filler rod when you're welding an outside corner like that. Just run the bead.

[kevincaron]

@devilkin9001 True but this was a demo. Had to add all the factors to see.

[rcfreak2493]

im buying a portable axy acetylene kit and was wondering how much welding time i could get with a 20 cubic ft. oxygen tank and 10 cubic ft. acetylene tank.

[kevincaron]

@rcfreak2493 Not sure. All depends on the size of the tip you are using and the pressure on the gauges. Also how the knobs on the torch are set.

Maybe a few hours, maybe a few days. Sorry I can't be more help.

[992F]

you will get haters for every single video on here. If I could oxyweld I would but you have some shade tree knowledge I can use. thank you Kevin!

[kevincaron]

@992F yeah, I have been burned so often I have really thick skin!

All is well in Kevin land!

[corycmelvin]

I know you mean well but you really have know business trying to teach anyone. Ugly welds, setting your equipment on fire, improper terminology etc. Keep learning yourself there are plenty of qualified teachers out there.

[kevincaron]

@corycmelvin Thank you for pointing out

what I have been saying from the

beginning.

I am self-taught and not certified. If

someone like you would step up

and post videos with the right way

to do this stuff, I would be happy to sit in

the back of the class.

[freddytk421]

Qualified teacher tend not to do it for free like the folks here on youtube. He's doing a good job of getting people exposed to this process and they can learn more if they choose.

[ojsdaddy]

@corycmelvin What terminology did he use wrong? Just wondering.

[jeterohjeter]

What is the filler rod for?????

[kevincaron]

To fill the gap in my poor fitting joint. You can just fuse weld the plates together if your fit is perfect. Sadly mine is not always that good.

[MrMarcoSharks]

@kevincaron looks like ur not getting any root penetration at all, but good effort anyway.

[kevincaron]

On a piece of scrap plate with a coat hanger for rod, I do OK. Remember, this is just for show. This was a question from a earlier video that I was trying to answer.

If you would please post up a video with the correct way to do this ALL the folk who watch here can learn the "RIGHT" way to do this.

Thanks for posting.

[Newfoundlander86]

Dont use coat hangers to weld with. If its on your cars exhaust it MIGHT be ok. Use the proper rods rg 45 or 65. No one can possibly know what the metal composition of a coat hanger is.

[kevincaron]

If you are doing "real work" I absolutely agree. I am just making metal art. I have used coat hangers on exhaust pipes for years when I had my garage. I also build an off road sand rail for use here in the desert and a lot of the welding was done with coat hanger. When you can't afford the good stuff, you use whats on hand.

[aklyman]

Thanks for the video, Kevin. I bought my O/A rig for brazing copper as a HVAC technician. I've decided to "turn up the heat" and try welding with it.

Practicing on old bed frames to learn the technique, I've found that when force is applied to joint, the metal snaps just to the side of the weld. Can quenching cause this? I'm not sure exactly what type of metal its is, though I imagine some sort of steel.

Thanks,

Alex

[kevincaron]

Yes, quenching will make the weld brittle. Or you may not be getting enough penetration. Try turning up the heat.

[freddytk421]

Bed frames are brittle metal that will break by themselves. Try getting some real angle iron at the scrapyard once you are out of the practice phase. it won't beak as easily and don't quench.

[VisorBlue]

Cool! Thanks for this.

I like O/A best, so versatile; weld, heat, cut, braze -- poor man's TIG. :-)

[roninslam]

Good demo. I agree this is a great prelude to learning TIG.

[kevincaron]

Thanks, I have fun making these.

Check back often, we update about once a week.

Please don't forget to give me a rating.
