The guys were laughing at me, used my elbow on my pedal had my helmet cranked so tight it may have been cutting off circulation (with a hairnet on the grip sucks) straddled 2 pieces of frame..lol Maybe I should start yoga...

Been a lot of little repairs this week, hope to get cranking on some sanitary pipe tonight

[ScottFc3s]

That's sch 10, typical my I'll put a bevel on it and tack, then backpurge and use 3/32" filler..you can get full penetration easier that way.

You can weld sch 10 butted but you have to crank it up to get through.

I ended up welding it butted at 65 amps walking the cup. Learned a lot. Wish I got my purge better, this big pipe is tough. I made a dam inside the pipe with cardboard cut into a circle and taped to the interior, with a hole at the top. Ferrule side was a cap with fittings I taped off and brought gas into. It welded out nice but I should have overlapped my previous welds more on my tie ins. I don't see too much more of this size coming across my table any time soon but it was a fun project. Good thing the stuff that touches this weld goes straight to the biodigester.

Little job that tested my patience and skill...

304 screen .050" diameter to 303 bar stock 1/4"...was 548 welds! Superior cup...

I know you had fun with this one why was 303 bar used??

@LtBadd Man I can't wait till the rest of the shit is gone...only because it was here, to tell the truth most mechanics I work with couldn't tell the difference or even care about the difference. I was mad, you give me something difficult to weld anyway by design, then give me 303 for the frame.... thanks.

When I start mentioning different filler and material grades and why you use what I get the "your just he welding nazi look or you think your better then us look" at time I feel I'm the only one that cares.

An old vendor slid 303 in instead of 304 at a cost savings, the buyer had no clue what the difference was and the vendor said "it will preform the same".

Quit complaining...it could have been galvanized screen

I feel the same man. 4943 would be a much better choice in filler for what we do at work since all of our welds (for the most part) get finished flush. Mention cost to one of the head welders, he responds "Don't waste your breath, they'll never do it."

Ask why we use 308 to weld steel bolts in stainless frames and vice versa... "It's what we have. They'll never buy another alloy, you're wasting your breath. If it bothers you that bad, use 316."

Me: "You guys that are too lazy to grab 70S2 are going to have a bad day if one of those pieces for a quartz wall retainer break and you welded it with 308." "It's what we have on the table, and it welds nicer than carbon wire." This is more of a shiny mill scale versus clean steel issue, as it seems like half the parts are 1027, which is a dream compared to the A500 that the other half of the parts are made from. That oily black coating takes a lot of finesse (and swearing) to get through to where you have clean steel versus polished mill scale. It skins up a weld done with 308, but to the people that happen to look at them as they go out the door, it looks better than a filmy Grey looking weld done with carbon.

I think they summed it up best in podcast 11 with David Blackburn where they talk about "All in welders VS Rod Burners" and I find that the crew on first shift seem to be rod burners, and everyone on second shift tends to be more geared towards understanding why they are doing what they do, or why myself or my shift lead question why they are doing something this way vs another way. I've also been teaching all of them how to use the Dynasty that's in their booth to its full potential, with pulse and amplitude adjustments on AC. First shift could care less, they use a profile one of the guys came up with in a few minutes that gave them relatively decent results.

Nothing exciting, I had 14 of these steel legs that needed welded to plate.
Used ER70S-2 and ~180 amps

Was Tig mandated for these? To me thats totally Mig territory.

In a way, our MIG unit is in storage.

[GreinTime]

14 parts?! That's a gravy TIG job! Try doing 150 of those with TIG lol

i like doing that kind of stuff but not 150 of them..........
by the third one your in the groove, buy number 100
it would be WTF.

I'll take a picture of these chair frames we did when I get to work this afternoon, I think we did 225 over a week, with 3 people per shift welding them... Now they are getting skins, which is taking less time, but are more tedious.

Nice looking welds LtBadd !

[Ryan_82]

I'm still a student and this is what I did today:

Some schedule 80 carbon pipe in the 6G position, Tig root, Tig out,

Not sure why the photos are rotated that way, probably my cheap phone.

[Coldman]

You did a nice job on the cap. Is that walking the cup or free hand?

Thanks. Walking the cup. It's a little harder with pipe that big but using a number 12 cup helps a lot. Since it's 6G I do it left handed on one side and right on the other. I'm planning on trying to test soon so hopefully it goes well.

Best TIG result so far for me, except at the end when I touched the rod to the electrode and things went wonky. I'm about half of an 85cf argon bottle into my TIG career at this point.


This is for the TIG pedal I am building, it will have three potentiometers, one connected to the pedal and two that will be here on the front, to set the lower and upper range. Copying the actual kemppi pedal on that design feature. You can't just set that on the welder on this machine.

You must be a lefty?

Dennis, I think you're doing quite well.
