The Welding Thread

[mrsleeve]

If it wont weld .250 well then put some some bevels on the the parts and make a few passes, you dont just weld .250 material in one pass unless you have some very expensive and specialized and generally semi automate equipment


It looks like a braze weld, basically a solder joint, hope it does not have to hold up to any kind of stress load

the hydraulic ebrake setup will be mounting on this plate. wasn't quite long enough so i had to add that little section on

[flyboyx]

What is this parts purpose? It looks like you have it stuck together just fine as long as it's not required to maintain any structural integrity. Braze will never be anywhere close to the strength of a weld.

[jalopi]

so i decided to try my hand at braze welding since my little hobart doesn't really do 1/4" materials. bought sticks already coated in flux. i know it doesn't look pretty, but other than that how'd i do?

Most of my T-shirts look like Swiss cheese. ;)

I welded for a morning in a tshirt once. Never again.

Well well well, I guess I didn't learn my lesson after all.

The bucket on my grandfather's tractor busted open at the back almost all the way across, and the front bottom corners had the sacrificial bits worn completely away, so my stepfather(Laurie) and I went down to try to fix it.

Laurie was running an Oxy acetylene torch with ER70S-6 rods and I had my little Mig Pak 10 + Bottle and a couple grinders to remove rust as best as I could.

The breaker in the barn kept tripping and I tried 3 extension cords before I found one that seemed to lessen it. Welds looked pretty brutal for the most part, The metal thickness varied from ~1/8" to wafer thin depending on how hard it had been dragged in that particular spot.

Anyway, since I was dragging the woman along, I was rushing to load the car and didn't bring my jacket. So I spent at least an hour welding in a Tshirt before I thought to ask for something to wear. I think I'm almost done peeling now, but my bicep is now two very different colours.

To add insult to injury, I ran out of wire and opted to switch from ER70S-6 for some old flux core shite that came with the welder. I forgot how awful that was, and as we were almost finished, a good sized piece of slag dropped right into a tiny hole in my glove and landed on the tip of my index finger. There's a nice black dead spot there now.

I have decided that getting a MIG setup is going to be the best direction to go. I have a trade worked out trading my Everlast 140st for his Lincoln Weld Pak 140. It's all set up for gas and is barely used.

All that needs to happen is him to have some spare time to meet up. Been 2 weeks now.

Not the prettiest, but for a 1 week crash course with limited prior arc welding experience..

Got my horizontal, vertical, and overhead T-joint AWS certifications in both Stick and Mig, also certified to stick weld pipe. The class was $1500 and I walked away with $1400 in certifications, so I imagine the Company will be pleased with their investment.

Did more welding over the weekend.

Short little stitch on a home-made tile scraper I made.


Welded on some V-band flanges for my westegate dumps


Need to do a better job of taking actual pictures of the welds for this thread.

So I did some welding for my dad last night. He is a division manager for a large material handling company. A tech at one of his locations was trying to repair a large hydraulic reservoir tank for a forklift. The guy proceeded to "weld" over the cracked areas without cleaning out the tank......cleaning off paint.....basically no prep what so ever. I really should have gotten pictures, he just kept gooping (not worthy of being called a weld) more and more filler metal on the areas. My dad happened to catch his masterpiece, and brought it over for me to....critique?...haha. It took me 30-40 minutes with a grinder to get back down to the surface metal.

Here are the results after welding. I had to run pretty cold (110 amps) and run a wide weave. the metal even after properly prepping was still oil saturated. to much heat and it was just blowing out.

Once I saw where someone tried welding their clutch fan nut to the aluminum fan clutch. Worked as well as welding dog to wood.

That is what bailing wire is for.

[ForcedFirebird]

This one time I tig welded a piece of wood to a dog.

Yeah I tried. All Smith really did on this was take their standard single flow meter, toss in a Y block and them put two gauges on that. so its like to lefts if you will....put a left on the right and its backwards.

Damn.

I remember having an old L-TEC welder at my one job and the flowmeter had a square sight tube that spun and had different measurements on it for each mixture of gas you'd use... Don't see that anymore.
