So, you think you can weld?
Take a look at this pipefitter's work:

Imagine what a custom exhaust could look like in his hands...

I bought myself an AC/DC TIG for my 50th birthday. I'm now 55 and I still haven't worked out how to set it up, thank God for my MIG!

Ha! Got a knee mill for my 50th and yesterday I came to conclusion I suck.

I saw SS fittings for nuclear power station welded on a rotating jig and the welds looked like what RAF posted.

Nothing like nice Tig work......
..sure adds a bit to a machine..

Love to see good craftmanship. Puts me in mind of the Honda Video regarding the building of RC30s

I especially like the head stock welding. I occasionally check my own RC, and yup, they did a good job there. So thanks lads.

Me, I have tacked together gates for fields on my sister's farm. Wasn't elegant, only functional.

A freind has a company called Pressure Vessels Incorporaed (PVI) and they use "jigs" that have rollers on them. (Not real sure they call it a jig.) The pipe they are welding end caps on is usually over a half an inch or bigger, so they roll it over while welding several times to fill up the space. They have a funnel that drops flux on the top where they are welding as it rolls around. Years and decades of doing it makes it look easy.

Yes, same thing, different continent:

I called it a jig for the lack of better world and my limited vocabulary

Those are welds that you don't want to grind and paint. You just leave them in their natural glory.

A Jig guides a cutter, ie drill, jig..
A Fixture holds a workpiece while performing. Various operations on it..ie, welding fixture..

Thank you, Frank. You would understand Haltevorrichtung too, wouldn't you

Once upon a time I could cut a bevel with a torch that looked just like the ones that came on the pipe and make cover passes like those with a 7018 3/32" stick rod. These days not so much, my greatest welding job was the plastics department at the Maytag plant. We put in an 8" loop around the department with 4" lines between the loop sides dropping 2" to each machine. It was fed with a 10" manifold and 5 Ingersol Rand screw compressors. We ran tie ins to other systems and could run the entire plant if needed.
A couple years ago they went in with 2 large track hoes and snippers and cut apart the entire building and back of the plant. It still sits empty.

Hey Faux Fiddy, that's a Sub arc machine you are talking about. I was watching one at a fab shop that made refinery pressure vessels. That's thing was burning 3/16 wire at something like 1500amp!

Wish I had the pics of the bevelling my brother does with track machines he sets up..
Some of the bevels are 8 inches across....and like 20-30feet long.
I think the things with the. Rollers are positioned..

Yes, and the flux falls off in neat pieces. I saw it done in the above factory with valves for nuclear power station, all SS.

Some of the welding machines where I work are set up for sub arc when needed and yeah they put out a lot of wire, you don't need a helmet because the arc is completely submerged in the flux .... which I guess is why they call it sub arc. Our welders only use it when they're welding something that's really thick and even then they'll start with a few passes with a mig at first to build it up, the sub arc is putting out so much wire and amps that it will blow clean through a bevel if they don't.

Don R · « **Reply #21 on:** August 19, 2015, 02:43:42 PM »

I worked on a submerged arc machine at Butler MFG. We loaded flat pre-punched plates into an air powered jig and clamped them in, then the submerged arc machine welded the plates into beams and columns. The excess flux was sucked up and recycled. Later stick welders welded on the end plates and flanges.

Sunday a buddy called, a drag racer was stranded in the center turn lane with a broken trailer hitch, that thing snapped off clean, there was no penetration and a slag inclusion in the corner. The weld bead had no penetration and the edges of the 2" square stock were exposed.

That's just criminal. The company ought to be footing the repair bills for that one, along with incidental costs associated with the loss.
Definitely should be outed if they do Not make good on it. Maybe even solicit the local news station to see if they would bite. Don't hitch companies have to pass certification or other testing marks to ensure that they are safe and legal to pperate and sell in the US? I would see if I couldn't cause them grief with DOT or whatever agencies allow them to operate if they brush the claim off.
