The Welding Thread

[marshallnoise]

I think doing spot welds without using gas is VERY difficult. Which Eastwood welder did you get?

[doorman]

Here's my second try on 18 gauge.

3 small tacks, ground a bit


Back side



Bent over by hand




Everything I've read and watched points to getting good penetration and welded completely that it looks like a solid piece when done.

You ground the fucking weld off. What do you want input on, your choice flap disc grit? Primer selection?

I thought the idea was to get it welded well enough and ground smooth enough that you couldn't tell it was welded?

Trying my had at sheet metal welding


16guage
Flux core Eastwood welder



Ground down a bit and hit with an 80 grit then 120 grit flap disc




Self etching primer

Shot some dupli color black on it and letting it dry

Give me some input please!!

Trying waffleswaffleswaffles 18 and 22 gauge now

Did you get the 3 in 1 thingy, or the 30" folder (not really brake per say).

I got this guy. Which is the second thing you said. I believe.

That things cool. I got the el cheapo one from harbor freight. I built my entire car with it. May not be fancy but served its purpose. Mine was the one that bolted to table top

Didn't like any of the budget brakes, so I made one with left over credit I had at the metal supplier from last year. Bought 67lb of usable drops for $53. Just walked around and found random piece of solid rod that fit in another scrap of tubing. 3pcs of angle iron, some scrap .120" 1.75" DOM tubing, a short stick of .095" 1.5" tubing for a handle, some grinding and welding later. (EDIT: It's temp welded to a piece of channel to test, still have some fine tuning on it)..

Fits under my hood, haven't been poisoned yet:

[IronFreak]

Zinc is no joke. we do a large amount of galvanized welding in our shop. I got really good at holding the run as far away from my person to stay out of the plumb.

[DER E30]

Zinc poisoning is no joke, it freaking sucks, you feel horrible for days

[4x4_e30]

Somebody (middle finger guy) rammed a face mill into a 10,000lb die at work. Taught myself how to weld cast zinc:



It took an industrial propane space heater 4 hours to get it up to 200deg F. blasting directly underneath it, and it was warm for 2 days after that.

Miller Syncrowave 351, only had a WP20 torch so I had to keep the amps at 250 or stuff would start to disintegrate. 1/8" E3 Tungsten, zinc brazing rod as the filler. It's much more tricky than you would think, melts around 750deg then poofs into a white sooty fur that covers everything right after that. All the while it's constantly off gassing zinc vapors that you hope your respirator will take care of. But I drink a half gallon of milk just in case.

I think I just clued into why I always had such a shit time with my old mig. I've been welding on 15A circuits the whole time, and often with an extension cord, not always a good one either.

I'm running a dedicated 20A circuit to my workshop now, and I picked up a 12GA extension cord for when I absolutely need to do more than just tack something outside.
I really think it'll make a difference.

I run my MIG on a dedicated 70amp 220v circuit with 8awg to a plug ~15' from the panel, then either plug the welder direct in there, or have a 40' 10awg stranded flex extension cord.

More juice = better welds. You are creating an arc of DC based on your AC input.
