How to weld Thin metal to thick PART 1 using the Cobra Torch (Tom Gingras)

Thanks for the video, had to skim through some portions, but your style is exactly what I was looking into. The closeups explained far more then I had previously realized from just the first viewing of this video. In all regards, thank your for your contribution

Well for one thing if you think this type of welding is obsolete, then you're not a welder. They use it in the oilfield on drill bits. It's also used to over lay when you need a higher temp. It's not obsolete.

Welding with the DHC 2000 with cutting attachment on. Would never have thought of that. How cool!

No doubt about it, I have to get back to welding. Thanks!

@freddytk421 You're right. If this is a backyard hobby project, then who cares?

However, if he's selling his work commercially, and does several project in any given month- a used TIG welder (for example) would save him thousands in unnecessary labor per month. Material thickness would become almost a non-issue. He could also go to bed mind knowing that his welds were now stronger, easier to make, and simply much better-looking. Furthermore he would save hundreds in unnecessary fuel gasses.

@TSorovanMHael. He has all of those processes at his disposal as do I. He teaches them and is a professor in a college. A torch provides more control and also let's you bend and shape as well as weld. He migs tigs sticks and oxywelds stuff as he sees fit. I know oxyfuel is ideal for certain situations and I for one don't care about the cost.

[TSorovanMHael]

@freddytk421 Yeah, I agree. Art has no *practical* value. As an artist, he has the right to take as long as he wants, use whatever method he wants, and charge whatever price he wants for his work. I don't know much background about the guy's situation. I'm not trying to criticize him or you personally. I'm just saying if i were in his shoes I'd do somewhat differently. You have to ask, how much is that level of attention to detail important to you? How much value doe it add to the piece?

[TSorovanMHael]

@freddytk421 Thanks for the feedback, by the way.

[freddytk421]

@TSorovanMHael Sorry I got mad at you but thats like going on a video where someone is showing how to hand stitch fine garments and saying a sewing machine would be faster and better. It's like "no shit sherlock" this isn't about those processes there are other videos about those if you want to see that.

[TSorovanMHael]

OAW is an obsolete process, and has no place in an industrial welding environment.

Other welding processes such as GMAW and FCAW are faster by far, easier, and produce welds that are superior in every conceivable respect.

OAW produces an unbelievable amount of heat input which is obvious in this video. The same weld can be made with a MIG welder in less than 10 seconds.

[freddytk421]

@TSorovanMHael he is making art doofus. Who said anything about industrial stuff? Did you just learn that in school today and wanted to show off your new knowledge?

NICEE!!! I'd like it more if you showed me step by step ;p

[freddytk421]

this is not me, but I go over most of it in my other videos specifically hobby art welding episode 1 the torch. look at my playlists.

[dansdismantling]

good one!

I love texture of expanded metal. I like what he said about backing off the heat is just as important as.......

I have never tried using a welding rod to catch excess molten metal from the puddle, I'll give it a try.
