what do you clean the metal with prior to welding, there is some oil on it now?
Answers:
I usually clean it with Simple Green which you can get at a hardware store, but any degreaser will do. You could use dish soap if you wanted. I clean it again after so that I remove any grease and such that I might have missed before painting/sealing it.
Other answers:
basically anything that would remove the oil and leave u with a clean bare surface and no residue...dish liquid would work just fine

you can clean the metal with an alchol (something that evaporates quickly and is not flamable after so) or soap and water will work. Or you can use a wire wheel and clean off the metal.
Either will work. I suggest the wire wheel (attached to a drill or something depending on how big the piece of metal is)
Oh wow, bad memories, I worked with my dad one summber and we built a pool fence. He made we wipe down every single piece of steel with paper towels. I didnt put anything on them, and I'm sure I didnt get all of the grease off, but it got enough off, that the paint stayed.
Use a wire brush on the spot to be welded, the rest will burn off when you weld.
