Can't remember the names of which is which but when I was trying to learn that type of welding is was the most tedious shit and I never got the hang of it.
But to be fair it was just a holiday course I had to do for uni which was irrelevant to my actual studies so I didn't really care.

like a stack of dimes, just the way it should be

>> No.58292

You can cheat with a lot of newer TIG machines and just use a slower pulse frequency to get the stack of dimes effect.

As I understand it, it's no better or worse than a standard weld in terms of structural integrity, it's just an aesthetic thing that was popularized by NASCAR.

Oh god, that's hard to look at. Somebody should have spent a little more time practicing with his mig rig.

I took a semester of welding in highschool about 10 years ago, we mostly did shielded metal arc welding (stick welding) and some oxy acetylene stuff but not much. at work we have a mig welder and my harbor freight belt tool started to crack. so I decided to have a go. It was the most simple thing on the planet, anyone with half a brain could pick it up and run a bead. It took me a couple of tries to get used to the wire feed but after that I made a decent weld, it didn't look perfect and I had to grind it down a little bit, but that right there, well what the fuck is that?

In high school for a "occupational education" thing I had I decided to weld up a wagon with my dad. I made some welds with 6010 rod that looked that nice. Fuckyea stick.

Any welders/hobby welders still do oxyacetylene welding?

For some reason I enjoy this process more than any other...

I usually just use my gas setup for brazing or cutting. Occasionally also when I'm dealing with something delicate.

Um, you kind of pulled that out of... I don't know where.

Pulsed can be used to make ripples on thicker aluminum (.250+), when you want to run a bead that might not be absolutely 100% in terms of penetration, but it's quick. I have a hard time doing it that way, but it's a preference thing. I'm sure there would be a job where it would have its place.

For me (I say this because i'm sure there are welders with different preferences), I would only use pulsed tig when I was welding on something that wouldn't dissipate heat well, such as right near the edge of a thin work piece. Heat builds up too quickly, things get sloppy and hard to control. With pulsed, it's much easier to keep the heat out of the work, and so it looks better.

Ripples don't necessarily indicate a good weld. If they are too prominent, they are stress risers. The pretty ripples like in op's pic are also much easier to achieve on thin aluminum. Steel and stainless are different animals altogether. Generally you won't find welds that look quite like that on .250"+ aluminum, just by the nature of it.

A "perfect" stack of dimes could be a poor weld too, undercut and craters, cracks you couldn't see, there are numerous things that might pass for pretty but might not be structurally sound. Generally it's hard to make a weld as pretty as the one in op's pic with anything seriously wrong though. It looks like it's not finished, but if it is, the crater at the end of the bead on top does leave a little to be desired.

And for all you know, I could be talking out my ass. All I have is a very blurry pic from two years ago. I used pulsed tig on the edges of the .125" 6061 workpiece, to get an idea of the application of pulsed tig.

I'm getting into the tail end of a welding course. I just finished my last MIG project today. The rest of this week will be me catching up on stick welds and maybe my oxyfuel. So far mig is my favorite, but I'm really looking foreward to starting FCAW on monday since that's the kind of rig I will probably end up buying.

If anybody wants one, Harbor Freight was offering autodarkening helmets for like $35. Not the best out there, but they work well and I've definately seen a great improvement in the quality and speed of my welds. Being able to see better also gives me a lot more confidence.

Man I just saw that ad in the paper.

When I saw the helmet coupon I nearly shot a load in my overalls.

I'm probably going to pick up about a mile of electrical tape just because they're only 50 cents per roll.

I don't even NEED IT.

I fucking LOVE HARBOR FREIGHT.

I remember when I first learnt to weld.
My metal work teacher and I were really good friends, because he was a big joker and only like 25.
Anyway, he told me that I couldnt weld for shit, which he was right about. But then I learnt to just weld straight lines and shit onto surfaces just for practice.
Oh boy did I write a lot of CUNTS on pieces of metal to leave on his desk.

Now i can achieve a world just as good as OPs pic, its just practice and repetition.

Where do you work? Just curious. I'm an Operator at an oil refinery and I don't know anything about welding but it would be interesting to learn.

I much prefer my oxy fuel torch over my MIG for pretty much anything aside from quick tacks in tight spots. If I still had access to a TIG I would probably prefer that. Even then I would still have need of the MIG for tacks.
