damn, thats nice

nobody posts anymore?

Another industrial job. Coal plant in Oregon. We're replacing the pressed in valve seat with a pinned seat. I have to weld the pin guides to the valve casing. It's a stupid weld prep. Need to talk to corporate about this one.....

Weld was 2.25% chrome stick welded 6g-****-me-in-the-ass-super-restricted. I welded the side against the turbine cylinder because I'm the smaller guy and can actually fit there.

location guides are fixed to the alignment jig. Casing was heated to 450 degrees prior to welding.



"prep". It's a nipple fitting at an angle on a round casing. You can't even really see the bottom of the prep. it's retarded.




Like I said, super restricted 2.25% chrome stick. The only way to get to part of it was to bend the last 1.5" of the rod 90 degrees and use it that way.




I'm not super happy with it, but considering I had to weld 50% of it upside-down, and the other 50% hugging a 450% oven, I think it turned out better than it didn't.

It looks a lot better in person. Camera flash always makes stick welding look ****ty.

Little reservoir 80 gal

MIG action 25.5 amps 480 wire speed. U welded MIG with tig gloves today, my fingers burn like a mofo holy crap. **** gets soooooo ****in hot haha

still gotta touch up on top of the channel with TIG

[euro-sudaka]

PINHOLES are the worst enemy ! acetone=BFF this one had 0 pin holes first shot on the pressure tester, i put my fist in the air out of excitement Cause usually I get one or two on the whole tank which means more work, more work= no good

[euro-sudaka]

Last one and I stop with the whoring, :p

[tripwalking]

How did you get it to float??!

[turtledub]

Anyone have any thoughts on this welder?

Hobart welder, good units

Any tips on doing anodized aluminum?

I welded up a oil return flange last night, anodized to anodized. Ground the surface with a tiger paw, then acetone bathed and gave it enough heat to not form a puddle on 70/30 clean/penetrate to try and break up the anodizing, then went. Still came out unpleasant looking. It could be that I haven't done aluminum in almost three years.

Ya, grind that **** off. Or mix a solution of water and , soak the part for a few min, and wipe clean. The lye will eat the anodize off and leave clean aluminum. Its how I prep parts for anodizing or strip them to re-anodize. Last time I welded some AN bungs I just attacked the hex with a wire wheel, welded really nicely after that even without cleaning with acetone.

[speeding-g6O]

anodizing prevents conductivity.

[Pat @ Pitt Soundworks]

I did grind the surface of the flange, and the hex. But I forgot to grind the sides of the flange. That's probably where my trouble came from.

I have heard that oven cleaner will eat through the anodized finish and leave a clean surface to weld on. I would hit it with acetone still but the oven cleaner should at least take the finish off and get you down to bare aluminum.

Turbo Cavalier manifold, tacked for test-fit. Had some trouble getting that one 45 tack...

Yes, it does. Works wonders and I have used it many many times.

[Pat @ Pitt Soundworks]

Not as good as you other guys, but I'm a fast learner.



edit: damn that's a bad picture

[5mall5nail5]

Not totally new to welding, but just picked up a Miller Diversion 180 and a couple bottles

I now have a Hobart Handler 140 w/ 80 argon/co2, and a 330 cf (I think) argon, and an 80 argon.

This is what I got for now

I am learning still, but made some decent beads

Looks like your off to a good start!

Thanks! I just need to remain consistent

I run an early 90's Thermal Dynamics TigWave 350 AC/DC.



Tuning the welder up for some Aluminum welds...



Electrical panel cover boxes for a pipeline company in Canada.



Modified front primary drive plate. Was a harley, not it bolts right onto my Kawasaki. (Spline conversion)



Handrail base plate for a museum in Madison, WI.



Single pass metalcore in a structural application. I think this was a Miller XMT with a feeder. I dunno... I hate wirefeed welding.



Flux core on a slide tube for ventilation.



.035 Hardwire a blast vent door.



Multipass 3/4" 1/16" Lincoln UltraCore, 6 passes, end termination.






And a chinese weld, just for something to laugh at:



And these people want to be the next world dominating super power.....

Here's some more industrial action for you guys. I was flown up to Minnesota to refurbish two valves at a power plant. The robotic welder **** the bed at the 90% mark on the first valve, so we had to set up the cwf and do it by hand. 26" diameter, 300 degree constant pre-heat using induction coils, sitting inside the valve. Three faces were done, the seat, the face, and the backside (locating face for another internal part). It took four 12 hour shifts to get it done. 215 amps, no foot pedal control, no hf start, and just a constant speed 0.035 stainless steel 410 on a wire feeder. The back side was done with inconel 1/8, 150a.

It ain't pretty, but after you sit in an oven for an hour, welding below your sitting surface, your welds will start to look rough as well.

After a couple days of post weld heat treating, machining will begin.

Oh come on, you know we all LOOOVE to do buildups. lol

(No.... we don't.)

If you ever get back up to MN LMK.

[Pat @ Pitt Soundworks]

Every March/April we go back to the plant for more work. We gonna have a sleep over?

[irishmpls_2]

Which plant do you go work at?

[Pat @ Pitt Soundworks]

Prairie Island Nuclear. We do others, but that's the one I've been to a few times.

[irishmpls_2]

Never been inside Prairie Island. Only Monticello. Never really liked buildups and repair stuff. I prefer the start to finish fabrication over it any day of the week. I just don't have to attention span for much else anymore. Hats off to you for your patience!

[TIGninja]

I have never done much in the repair but I have dome some in shop nuke stuff. I will pass on the post welding

[Pat @ Pitt Soundworks]

Yeah, it's not the most exciting of work, but I meet some cool people, and I get paid to travel around the country, so it's not too bad. It beats the fab-shop work I've done, punching out the same couple products every day.

There's quite a bit that I do that's quite challenging - makes things interesting. That post welding was probably one of the hardest things I've done. That, or a 2" 5G weld where I was crammed in a cubby hole, and had to have someone hold my legs down while I hung off the side of some scaffolding inside a generator haha.

[irishmpls_2]

Gahhh...

that brings back memories of climbing inside of a huge coal dust filtration tank and repairing tube sheets for filters at power plants.

Not work I miss in the slightest.

No thanks. I'll stick to staying home and working on car and bike projects for myself and others. Plus, I get to listen to Slayer whenever I want.

Man ive been pricing new additions to my welder this morning.... Making some additions to my Millermatic 251..... I already have the 22a feeder, and a 30ft lead for my steel set up that im gonna mate up with the machine then Im gonna add a 30ft aluminum pull gun to the regular feeder. Ill pretty much be able to get any where i need to for steel or aluminum with one set up! When i get it all figured out and built ill post some pictures up!

Please strap your bottles to the wall or at least take off the regulator and put the cover on. Last thing you want is a freak accident of it falling and having a 2400 PSI torpedo ripping right through your house.
