Default Stick welding Sheet Metal

I've read through this newsgroup plenty of times, and I know this is a
dead-horse type topic. But I was hoping someone has a step by step
web site on the finer points of stick welding sheet metal.

I got the following...
1. low amps, small rod (1/16)
2. NO gap, tight, clean fitup
3. Move fast (2 inches per second was what one previous posted said)

can anyone add anything else? How great would it be if someone out
there has a FAQ for Stick Welding sheetmetal. (I've googled, but no
luck)

Thanks for any feedbacks.

Wrong newsgroup.

Check out

sci.engr.joining.welding

Your best rod for sheet metal will be 6013.
Low penetration and very ductile welds.

If you need to run vertical beads, run them downhill fast.

I use 3/32 dia E7014 (iron powder in the coating)
at about 90 Amps AC to weld 16 Ga. or less sheet
metal. Practice by first laying beads on top of
..06" sheet steel without burning holes in it.
Next exercise is to close any holes that you did
burn thru. After mastering this repeat the exercise
on .03" thick sheet metal. Learn from the results
of moving too fast or too slow, also when using a
short arc and what happens with a long arc. HTH.

I'm not sure what gauge metal I'm working with. It's a hood off a late 90's
Buick Skylark (guess what color :-( ). That's my practice piece. Got it
for $10 at a junk yard.

I am able to lay a bead on the clean metal, no problem. I can do it
repeatedly without burning any holes. (30amps, 6013 stick, AC) But, as I
work on joints, that's where I'm having trouble.

Overlapping joints - I could get some spots to stick, but most other spots
ended up looking like a saw-tooth, with burn-through on the top piece.

___________
| |_____________
| | |
| Top X | X is welded spots
| Piece | is burn through spots
| | |
| X |
| Bottom |
| | Piece |
|___________| |
|_______________|

Where the spots are welded, it actually feels very strong. I can beat it
with a hammer, and bend it, and it doesn't give much.

Am I moving too slow? I'm trying to do spots first, as tacks. How fast can
/ should I move if I'm making tack welds?

(I've checked out AssieWeld.com thoroughly, and applied most of what they
describe.)

(I've posted this also on sci.engr.joining.welding, as well.)

Thanks for the replies.

You mean mono-space (*non*-proportional), and yes, Courier is an
example.

Based on *this* image, he *did* use a mono-space font, as it
looks fine to me, and I only read news with mono-space fonts. If he had
used a proportional-space font, I would expect the right-edge to be
jagged, where the text replaced the spaces with different widths.

Are you perhaps trying to read it with a proportional font?
After all, both ends have to agree, and with proportional space fonts,
there are differences between the same named font on different machines,
That is why the fixed-space fonts are the proper choice -- they work on
*all* systems -- even old ASCII terminals, or even with Teletypes.

He even resisted the urge to use tabs, which don't always work
between systems, and are certainly screwed up by the "" quoting marks
as people reply to the article.

Enjoy,
DoN.
