View Full Version : Did a little job on my open top welding table.

This is a piece of 4" pipe welded to a 1/2" plate. I took my time to get them as close as possible to 90 degrees. Did I ever mention that you can never have too many C clamps? ;) The first pic is the setup. The second is the weld. Do you see any spatter that the nasty CO-2 is rumored to cause? :D
This was done with CO-2 and .035 wire. I show a pic of what this was made for. It will be a few days. :)

Looks good overall. Only reservation I have is the China made pipe. Hope you cleared off all the lead-based paint off that pipe before you started welding on it. LOL

Working on your lamp post?:)

Big A$$ potato cannon? :rolleyes:

Yeah you could use that as an O/A potato cannon. I like air meself, the bigger they are the less you fire them, at least in suburbia.
I gotta make me one of those tables hehe.

Nice shop Mike. Great job on the welds also.

I can totally relate...I had a job where I had to basically weld a post onto a flat plate and it was to be used as a load test jig to mock up for wind tests. Getting a post square to a plate isn't as easy as it sounds. I used a digital level, shimmed the whole post 1/16" from the plate, tacked one side and then used the level to make sure the pole was square, then I tacked the other side of the pipe. I then did that 2 more times in the othe other direction. Turned out to be pretty **** square, but it wasn't as easy as I thought I'd be. Haha. Maybe I'll post photos, but I don't want to hijack this thread.
Can't wait to see what it's being used on!

I should have a picture in a few days. Right now it is 3' in the ground inside of a 4.5" pipe. ;)

The welds look great Mike even with the Co2 shielding gas. Is that some kind of stand for something? I got quite a few of those 4" 1/4 thick tubes here that a friend gave me but I have no idea of any projects to do with them. :(
By the way nice table too.
Mike, were's the close up look of the weld, so we can truly tell whether or not there is a low spatter level.;)
What were your machine settings? If you were running one of the upper V taps (24+ volts) on your unit and pushing the 200 amp range, I'd be impressed with a low spatter level from COČ. For about the first ten years after my schooling, COČ was all that I ran. My old CK Systematics 175 produces the output characteristics, that COČ tends to perform well with. It isn't able to reach the output power level that your unit is capable of reaching. It only has 6 voltage taps. Top end is around 200 amps, but that would be with 75/25 (high end short circuit transfer), because there isn't enough voltage available to run COČ proper at this amperage level .
See, this proves the point, you don't need that gas mixer.:) 1/2" plate, and I 'll assume schedule 40 pipe, I would have more then likely went with spray transfer.

Dan, put your glasses on. :D I don't think there are more than 3 or 4 spatter ***** around the weld. Three 1/2 inch long welds around the pipe would have been plenty for the application. I don't know what the volts and amps were. I wasn't running it very hard.

Them 'lil acid resistant gray painted angle iron pieces look familiar.....

I wouldn't have messed with the braces, and all those C clamps...there is an easier way.
After you square the end of the pipe the best you can, set it on the plate in the circle you draw on it, then using your framing square, find out where the < 90° angle is and put a tack there....then opposite that tack, square up the opposite side, and tack it there...then repeat the procedure on 90° from where you put the first two tacks. It'll be plumb every time. ;)

so what are you gonna make the hat hook out of :D I have heard of heavy duty hat racks but I think I can clearly see you over built this one.
I really wonder what you are going to put on top of it.

I'd have to agree with Rocky D. If you tack it enough things won't move, if you want to be picky then tack them in a star pattern (think tightening a car wheel). Looks good though, I'd be hard pressed to do a smooth weld on a pipe. I still need to figure out my spatter troubles.
