Welding Tips and Tricks

It's actually a bank of 4 large screw compressors. But the tank it bypasses is about 6 ft diameter and 16 ft tall.

I'll bet that would fill a tire pretty quick

Very nice. And the work flow pics made it even nicer,

Hey Anders...would you back up next time you take pics...I can't look around your shop too well with those closeups

Like it Anders, simple design and looks good. Is that a porsche in the garage?

Pronunciation question:porsh or porsha

No matter how you pronounce it, it's only spelled one way!

Well yeah but potato and potaaato(sorry it's the best I could do)are spelled the same when actually written out but certain people pronounce them differently. Same with vase and vaaz(again sorry). Is there like levels or is it just who cares, worry about finishing your junior in high school?

WTF? Somebody spiked the punch didn't they?

Koolaid? Sure I'll have a glass.

Nothing interesting - floor drain for a shop to fit an odd size opening.

Perfect example of something that should have been mig or stick welded...

TIG welded it instead because I like it that way

1/8" material, 1/16" filler, 150 amps in an attempt to approach mig speed
(I was in a hurry) One that turned out pretty good

I hate you,.......... Wait ,I mean very nice work sir.

fifth street
how many centuries have you been TIG welding>...
craif

We got anyone in his area to go by the shop and see if this is real?

Nice work 5th!

That weave in the first pic is sick, but what is the purpose of the inner weave? Is it for appearances or does it serve a purpose?

Very nice welds. Very nice.

Thanks guys!
I've been tig welding professionally for about ten years. If anyone's in western Oregon come by anytime!

That weave was just for fun. I finally got a bottle of helium at home so I ran a bunch of random beads. I rarely use a weave at work and especially a triple weave,but they are fun.

Sweet!
I have the incredibly rare blessing of completely unlimited access to helium. One of our clients provides whatever we ask for because I use it in leak detection.

I made a bunch of trophies out of old car parts for the car show we threw a couple weeks ago.

And here is a 4150 holley intake 102mm Throttle elbow.



and some 3" intercooler Vband flanges

Fantastic work. Much better than chinsy cheap trophies

Just thought to post a little project I’ve been working on. This is to be a fairly robust rolling table to support a really heavy, cast iron, hot foil stamping press that a friend of mine uses for her leather work. The legs on this are 5cm square tubing with 2mm wall thickness.

As you can see in the first photo, my welding table is not really so heavy duty, being a little homemade affair with a 5mm-thick top that I threw together for myself. My usual work is metal sculpture and some simple hobby stuff, so I never bothered with clamping holes or such. This project is somewhat on the large side of things for me and so I’ve had to be a bit ‘creative’ to make things work out…. thus that armload of woodworkers clamps and a couple of nylon straps to pull the whole thing together. Pretty ‘Mickey Mouse’, but it works.

That torch you see hanging there is a 17-style with button control, which was just fine for the ‘walk-around’ I did - pecking a tack here... and then a tack there - prior to removing the project from the bench and welding it all out.
In the second photo the table is mostly welded out and I’m attaching the plates that will serve to mount the wheels. Since the project is larger than my little welding table, I clamped on some outriggers to serve as supports.

Of course, with such a small welding table I have no real way to lock down my work sufficiently to avoid weld-induced stress. I can only try to minimize distortion and then deal with the effects. In this case I used a precision level to first level out my support surface and then, once the plates were slid into place under the legs of that table project I used the level on the top surface of the project and made certain that it too was blocked up level. Sure enough the table had pulled a bit during the final welding and there was a wee bit of ‘air’ between the leg and wheel plate on one side. I compensated for this by first welding the other three plates and then, with everything clamped down, was able to weld-fill that slight gap between the other leg and plate so as to bring it round right. The wheels are fixed in place with bolts so even if I’m still a little out I can slip in some shim material between plate and wheel to compensate and make it roll true on a level surface.

Last of all I include a close-up of one of the wheel mounting plates in progress. I don’t think my welding will win any prizes, but it’s certainly good enough for purpose and I’m pretty sure that seam won’t let go anytime soon. Those clamps are there to secure the plate to the outrigger and to try to minimize the tendency of the plate to distort during the weld-up.

One last thing: I did sort of shoot myself in the leg when I designed this table. I used my #17 torch for most of the welding and the outer seams on the wheel plates, but the amount of space between the lowest cross bars and the wheel plates is just so small ( 4cm = 1.6inch) that there was no way I could even get the torch head in there. That CK-9 Super Flex you see in the second photo did allow me to wrap the welds around towards the inside a ways, but even there it was just a wee bit too tight to allow me to run the weld seam all the way through. ( big sigh of frustration! ) Stubby gas lens kit, anyone?

Lunch anyone?
