What are the metals? If your stick welding, most likely steel, I assume.
My next question is, what does shitty look like? Are you blowing holes
through what your trying to weld or is it bubbling up and really porous
looking.
No matter what metal, stick welding is tough on thin material. Ideally
you should TIG weld it together. If all you have is a stick welder, then
buy the smallest diameter rods you can find and keep your heat low for
thin work. Blowing through is usually because of too much heat. The work
thickness and rod diameter determine the heat setting of the welder.
I'd suggest taking the part to your welding supplier and talk it over with
the counter guy. Seeing what your doing, he may have some better
suggestions for you. He probably knows someone with a TIG welder that
will do it if you want to go that route.

I was attempting to machine the pieces for a metal "bobber" for my new
soft ballast tank's water level indicator (Foam just gives at depth, so
that's no good). The piece is essentially one piece 1cm in diameter 1mm
thick walls and 1cm in length and another 5mm 1mm thick wall and 1cm in
length tube with two 1cm diameter 1mm thick "washer" end caps with a
center bore hole of 5mm.
I can get the pieces machine out great, that's the easy part. I'm trying
to weld them all together however and I end up with some really shitty
looking welds. I've never attempted to weld something so "delicate"
before. What I'm trying to make here is a preasure proof bobber and the
end product should be something like a hollow bearing.
All my welding is done via stick arc welding.
Any suggestions?
