That’s why God gave us acetylene and oxygen, so our little welders don’t have to work as hard to heat the base metal for penetration.

Thanks for sharing. I'm one of those beginner/hobby welders and my take away is basically the wrong tool for the job. 120v maxed out for 3/8 material? Why is the flux core weld so much stronger than the MIG? How would stick welding compare to MIG at 120V?
@jeffharper75797 күн бұрын
I thank you also for showing this. I'm not much of a welder but some days I do good other times what was I think. I use stick and wire at work, some of mine looks great some not so and some of my good welds hold and others break or crack.

Tell tale sign is the sides of the weld are not 'wetting in' which is term known by welders which means the edges are bulging rather than smoothly blending into the parent metal. You can overcome these issues by pre heating or running hotter.

I see the comments all the time on Facebook. People will take one look at a photo of a high production stringer weld that used dual shield or spray, and it's the worst thing they've ever seen, the welder was lazy, didn't know what they're doing, blah blah blah. But as soon as something has little consistent weave lines in it (or worse, a huge row of overlapping tacks), it's automatically a perfect expert level weld. The stack of dimes obsession on the internet is out of control.

A consistent weld is better than a pretty weld. Consistent weld yields the proper penetration. Easy to lay a stack when its just melting the filler, as you aren't also trying to penetrate the product you are welding.

I did a bunch of videos on this exact thing on my channel. 100% running cold settings and stacking dimes to get the look results in poor fusion and very weak welds. Despite a ton of evidence presented in the videos I still had a significant amount of people say that’s simply not the case and say the numerous videos were wrong. To date nobody has provided a sample weld, cut and etch, or settings that will allow for proper fusion with some stack mig settings. Thanks for covering this, the more info out there the better 👍👍

Have loved your content over the years. I am not a welder by trade, I do it for fun. I am by trade a Mechanical Designer. Had this been a bracket from a system I designed it would have been a double bevel weld (bevel dependent on material thickness) with at least a 1/16IN gap. I learned early that every design I submitted for stress analysis that had a T-Joint weld was sent back with a required bevel weld, at least on the side of the most stress. For the casual home/small project use, hammering a test piece is fine, but most of the work I did on designs required an accompanying stress report, so we knew who to blame when it failed :)... And you are correct, it does not have to be pretty as long as it is done properly.

I was going to say you are asking a lot for a 110v/120v machine. I’m going to go out on a limb and say I doubt the specs say it can weld 3/8ths in a single pass on 110/120v, does it say it can weld 3/8ths in a single pass on 240v? If its a Millermatic 211 then 240v 3/8ths is the max size in a single pass (240v.) I think beveling the piece and using it on 240 if you can, if not multiple passes would definitely be the way to go along with beveling the piece you are welding onto the base piece, and even giving it a bit of a preheat if possible, do everything you can to give yourself the best chance of penetrating into the parent metal. You might even be better off using SMAW if that piece absolutley had to stay put.

Seeing the first pass and the first weld seam breaking, I was about to write "hey, over here in Europe we use to do some weld prep". But you said it all in the end. Nice demonstration why weld prep is not just annoying work but an absolute necessity. Over here most newer welders are "synergic" machines, setting voltate and wire feed according to the current asked (which is set according to material thickness). One can override the presets, but they're commonly pretty good. If my welds have a hump, it's not the settings, it's myself - the hobby welder. This takes out a lot of completey bollox settings that only generate good looking welds with no penetration. Btw, 3M Cubitron fiber disks are awesome to grind bevels on thick plates before welding. Started to use them a couple weeks back and wished, I would have known about them earlier.

@smurface5499 күн бұрын
@@6061 The ones I have are called Cubitron II 987C. Got them from Ebay, but it was a French seller, which might not be very attractive outside of Europe. I recently saw in a video on KZfaq that there's already a third generation availabe, but I have no first hand experience with them. In my experience, the backup plate also plays a role. Had a pretty soft plate first, but the results haven't been very good when applying decent pressure. 3M of course sells their own backup plate, which I have found working quite well. It doesn't get soft when heating up, like thermoplastic materials would do. So maybe pay attention to that detail if you'd give the disks a try (they won't cost you more than half a kidney 😀) When seeing videos of people using the Cubitron disks to grind a bevel, it's hard to believe that it's not a timelapse. After trying it myself, I was quite pleased, despite the somewhat steep price per disk.

For short circuit transfer, you'll only expect up to 15% (of material thickness) penetration. With spray, you can expect up to 25%. These are not my numbers, they came from technical research papers that I've read, done by welding institutes. In welding school, we cut and polished 1/4" welded t-joints to see our penetration. You don't have to etch the surface, you can polish it mirror shinny, then slightly heat color it. You'll be able to see your weld cross section perfectly.

Interesting how flux core is cheaper, doesn't require a bottle, is sometimes seen as a "lesser" process because the machines are cheaper, yet it does a better job in this case. That's one of the reasons that I like TIG, I can sit there as long as I want, add as much heat as I like, before I add a single bit of new material to the weld. I can even go back and dump a TON of heat into a failed weld, just to get it to flow again if I wanted to try to fix a failed weld without grinding it out.

Shouldnt make many sparks or noise just a sizzle with an occasional crackle. Welds will be blue, and virtually free of ripples.
