Welding Tips and Tricks

Oil soaked metal is the worst. I've done some SS tanks that were used for oil/ammonia/fly ash/ ??? Mix. It boiled out as you welded. You had to weld everything 4x to get one good weld.

I had to weld a broken piece from a meat slicer , the part that deflects the meat onto the receiving tray, and it was aluminum and it smelled exactly like fried hamburgers as I was welding it. Even cooking grease penetrates metal and causes nightmares.

On that note, imagine the smell if you welded the impellor on a sewage pump... Hamburgers is not my first guess.

Laundry cart for, among other things, adult nappies...(diapers). Lovely. I have also worked at the sewerage farm.

I have welded / brazed on the impeller for grinder pump in a shit pit. You are correct it did not smell like hamburgers.
If any one wants to know what it does smell like I'd be glad to mail you a box full of samples from the pit. You can smear it on some metal in your shop for welding experience.

I have repaired quite a few mower decks...the smell of burnt grass mixed with doggy poo poo will certainly get you attention as well

Made a little dump cart/ wagon for my wife. The wheel barrow was too much for her back. If I don't make it easier for her to clean out her flower beds then I have to do it. It's a win win.

Couldn't tell you how many times that style of wheel barrow would have been helpful building pools- what I wouldn't have gave for one. Pushing a couple hundred pounds of duty up a hill with one wheel was not a fun time.Especially when the pay was like 5.25 an hour. Now where is the seat for her to sit in and the hydraulic motor that drives it! nice build though. Might be a future project.

Mark,
Why did you use such heavy material to make that ballast box, 14ga would have been more than strong enough to support those weights.

Oh, wait, . . . . . . . . never mind.

Good job!

That wheel barrow cart is brilliant, great job on the steering.

Among other things I have rebuilt 2 different sewage digester tanks on remote sewage treatment facilities. Fortunately they are aerobic and not septic so the background smell was not all that bad, but when the grinding and welding started, UGH!

if you can't reinvent the wheel, reinvent the wheelbarrow!!!!!!
awesome
craig

Finished up another, replaced the bottom and all support round bar, straightened outer ring and welded it all back in.

Great work...as usual! Miss you being around.

Like the parallel blocks, been thinking about getting a couple myself.

My apprentice days in machine shop had to make jo blocks, 1,2,3 blocks, angle blocks and parallels, all from scratch entailed precision grinding and heat treat and use them to this day. Very good skill to learn. There was times when trigonometry was used and enjoyed the challenges.

How about climbing into a clarifier in a waste water plant and working/welding. My last job as part of the companies obligation to the small town they ran the waste water plant.

I'll put up a pic maybe, but I just want to thank Jody for the vids. I had to pop a 2 1/2 inch pipe plug off our air receiver today. A 3 foot wrench didn't work even with a 5 lb. hammer. Thanks to having Jody''s stuff in mind I just took a 2 x 1/4 inch piece of 302 ss and welded it on the side of the wrench with 309 rod. 8 feet long and me putting full weight on the end...maybe 1600 ft-lb on the plug...all on a ladder... did the trick.

Thing is, what are pipe wrenches made of? Wrought steel, right? I was worried about cracking but all went well... I was saying jeez... is this cast iron? Welded nice but the wrench metal glowed kinda bright near the puddle. Never saw that before.

Sure there's some sort of cast steel but not cast iron they bend before they break.

Would heating said plug and then waiting for it to cool help? or would that have the opposite effect?

Usually tools like these are a wrought/forged steel.

They can often be made from a heat-treatable steel so they can be tempered to make a very, very tough material. Sometimes sprinkle in some extra alloys like chrome and vanadium.

Hardness of the material is often clear from the fact that when they do fail (often spectacularly! ) they tend to snap/break and not bend.

Bye, Arno.

There was no way to get comfortable on this one so i had a couple of voids on the inside. I lost one of my tig fingers which i needed for the feed wire. So much for a pretty weld.
Hydraulic cylinder end cap, TIG @160 amps. Off to be machined now.

Here's that goof ass pipe wrench. The 1/4 x 1 1/2 stock draws a magnet so i, as usual, have no clue. But the job's done.

And here's what I welded today. Pretty huh?

The owner of the company collects 57 t.birds. If he'd had to drive to make money I'm sure he'd choose something a few decades newer.
This is a pic of a 16 ton press footpedal. The trip isn't adjustable but the brake kept creeping back on. (It runs continuous.. not single stroke) I just grabbed my fucks core and slapped a 1/4 rod to persuade it to play nice. Welding .
Some people don't get what nickel and diming really costs. People like us enable their ignorance by keeping shit running.

Decided to see if these rocket stoves are all they are supposed to be, will try soon, only had 1/8 inch 3 x 4 next one will be 14 ga. 4 x 4 made with intention of carrying in a bucket with a bunch of kindling and lid on top, I will be everyone's best friend on a wet morning and coffee is not ready.

I built a rocket stove. They are cool for 15 minutes and then....I gave mine to my best friend to take to his campsite. He amazes the neighbors by cooking sweet corn on it. He's having fun with it so it was worth it to build for him. If I still had it, it would have been cannibalized into something else by now.

Just started building one myself today. Got bored so I figured I'd make one at school. Of course I'm too cheap so it is gonna be angle and flat stock since I am not going to go and buy tubing. Should be interesting.

Some pics from the last week or 2
