Here's a picture of something I made at work last week. It's a filter that goes in-line of the product hose off a bulk pneumatic trailer. There's a screen inside that filters out "bad things".

I just recently started this job, and got immediately voted the official company welder of sorts. My boss was like "so, you went to welding school? Hmm, follow me...." And I've been making and fixing stuff ever since. In addition to that filter I've made a couple of adapters to allow a pneumatic trailer to blow into the top hatch of a railcar, as well as fabricated a clutch/idler-pully contraption for a gas-powered conveyor belt. It's a small transload and bulk-warehousing company, only 3 non-office employees, so we pretty much all do every part of the work.

Looks like some part of a space ship in the 60's.

jknight8907,

If you went to welding school to learn to weld like that, I'd be asking for a full refund.

SundownIII,

Dude, that was totally uncalled for. We all come here and post our pics, bad or good. Some people offer advice or praise. I, for one, don't think your comment was very cool.
He didn't say how long he was at school or what exactly he studied. He did get the job done and it was functional.
Maybe I am off base and over reacting. Or maybe you are buddies with him and just busting his chops. In which case, my bad, I'll shut up.

Looks like you got the job done and have a new job title. Is that GMAW or SMAW?

Good work on the design, simple and effective. Looks like it bolts together in the middle in order to allow it to be taken apart and cleaned out? Some more practice time, and you'll be welding nice and smooth. What machine did you use for that? Ohh, and I agree with Joker11. Sundown's comment was totally out of place unless for some reason he knows you and that comment was friendly, he should take some time to think about why he is such an ***, and possibly look back and figure out why he hasn't posted any of his own work...

Keep up the good work and practice :)

Looks good to me. Simple and effective always seem to win. An old timer once said "Pretty ain't what's holding it together"

Thanks for the kind words, Sundown. :rolleyes:

I MIG welded that, with the pos ESAB you can kinda see in one of the pictures. I agree the welds aren't very good. It was kind of a compounding of problems, basically a combination of not enough skill on my part to overcome the poor equipment I was working with. A machine that wouldn't feed wire right, a propane cutting torch that had a worn out tip and no replacement, etc etc. It holds pressure and does the job just fine, though.

Wintermute, yep, it can theoretically be taken apart to replace the screen. Cleaning it out is better accomplished either by shaking it out or sticking your arm in it if something's stuck. There's silicone between the two halves so not taking it apart is better.

I got certified as a stick welder in a community college program. Never did any MIG in those classes.

if you got certified as a stick welder then these welds really shouldn't look this way, spend a little time tweaking your machine, check the dtension on the drive rollers and the wire spool, i've found that if you put some nozzle dip on the wire where it feeds into the whip, it lubricates the whole whip going to the squirt gun itself, works wonders. sometimes the wrong size mig tip makes it start and stop as well, a .35 tip with .30 wire will look kind of right and somewhat work, but will keep fusing to the tip and shorting out. if nothing else remember you can grind down ugly welds and pretend they were pretty before hand. how much pressure is on this?

Spend some time with the machine and gey it dialed in right......what does it filter and what kind of pressure ?.... If more of you would listen to Sundown you might actualy learn something..... even if some of you are way too far gone....

It will filter spodumene (a type of sand from Australia) at 5-10 psi.

I'll post some pics of the project I'm working on now, a device to load railcars out of a bulk trailer, in a few days when I'm finished with it. It has much, much better welds on it. It's the most recent thing I've made and I think I'm starting to get the hang of the ESAB, the welds on it are looking really good.

If he wrote something resembling contructive critizism maybe they would listen. All he did was bash his work. Yeah, we all know those welds dont look so good. So give the kid some advice, ask about any problems he had. That kinda thing.

Your a gracious fellow to boot, so don't let em get you down. Practice makes perfect, so keep after it. Yeah the beads look bad but it looks to me like the fabrication was on the money. None of us picked up a gun and laid perfect beads the first time, well except for Zap. :p Maybe. Like some one else said, tweak the machine and learn its quirks. Thanks for posting the pictures, and post some more please.

Listen...

Nobody starts out like they know it all..:nono:
You did not come across like that and the new boss seems to think so..

That's good..
Gives you time to play around with things..

Next time he wants something done sorta like that just say "Let me get the machine dialed in with some scrap"..

You will impress..
You will also get a chance to learn the machine more and that is very important..

You are in a good position..
Take advantage while you can..

...zap!
