Trying to figure out how that was welded. I think it looks like MIG but am not sure, anyone else have an idea? For scale: the U is 5/32 and the bolt is 5/8 18TPI.

I'll be honest: I hadn't considered that. it's a shock clevis for a motorcycle, and I'm used to bike stuff which is generally thin so I don't consider stick. I highly doubt it was TIG, which is what I was told, but it was a used item and the price was right...

Its definately a mig weld, the start looks like short circuit but the rest looks like spray but the view angles are not great.

I could weld it with either, and make them both look like that.

If it was a stick weld, someone took the time to chip slag and cleanup spatter.

It's now installed on the bike so it's difficult to get decent pictures, but here are a couple that show something at least.

Also a couple of the original part, which I'm pretty confident is TIG

The first set - with a bolt rather than a threaded rod - were done by a shop. The second set - with just a threaded rod - were done by Fox, a rather well known suspension company. I also don't see evidence of the end of wire feed, which I would expect to find somewhere for tack tack tack. I see one thing that *might* be that, but could be from TIG filler too.

First one looks like stick to me, probably a 7018 low hydrogen. Second definitely looks stick to me, 6010 hyp.

The first one looks like stick to me. Probably a low hydrogen rod like E7018, but could be a smoother general purpose rod like E6013. Whatever process or rod was used, the welder did a nice job.

The subsequent pics look like mig. Especially that second one in the set where it looks like there was a spot of the "brown water".

that is mig, started out small pulling instead of pushing, small splatter beads on nut, also looks like small puddle from wire.

Just curious, the weld looks solid so what does it matter the process used? Could be mig or stick but definitely not tig IMO.

I dont care for all that, its too tedious. I like the first one best, let the machine do all the work. Where did you learn this?

Mig is very weak, I am a certified structural welder, Mig lays on the material it does not cut into it like stick or tig.

In that first pic I was field testing the HH210 before it hit the market. It came with spool gun but my main interest is steel. I had ran it about 10 seconds before that according to the door chart setup and said to my guys, now we turn it up and find out where the hi end is at on 1/4 material, didn't scale the metal. With 030 could turn it up till the ripples come out of the puddle even.
Chad is right, there can be issues with mig, in this case for general fabrication concerns this weld is good as any. Solid wire and C25 have good mechanical characteristics, about as good as some 7018 provided its hot enough and a competent operator etc. There are a lot of faulty wire welds in service, have seen a few especially in rugged applications, seen a pic of factory hitch fall right off an RV, couple different factors but one being the welder.

The second pic as I recall was a piece of rigging equipment where the actual load would hace been served by 3/16 weld at each end of the clip. It was getting painted etc and a minute extra to add some weld for nice finish was no big deal.
