Brazing vs. Welding
In a small Oxy-Fuel launcher, (2" metal chamber, 1" metal barrel) would brazing be an O.K. substitute for welding? This wouldn't be metered or anything, just a long shot of mapp and a blast of oxy. I am asking because I recently aquired a small oxy-mapp hobby torch and I would prefer to braze because it uses less fuel.

I would suspect that you'd be able to get away with brazing, but that would depend on the exact design and joint geometry.

You make it sound so casual, "Soldering isint working on the wires, lemme get my neighbor's arc welder, that should do it".LGM wrote:Well, never mind. I just tried to braze the pieces but the metal is too thick for the torch to handle, I think I'll just see if I can use my neighbor's arc welder.

I wonder if there is a weldingwiki on this here world wide web thingy? Better be a good brazer if your useing high pressers. If your going to use a acr welder don't over heat the metal, just make the two pieces penatrate each other.
EDIT: Opps, three pieces, the rod/wire counts.

If you are going to arc it, I would make a couple of passes on some scrap 3/16'' or 1/8'' steel plate. Do a couple of times to were you get to a point were you can get a good solid bead. As for the rods, go with E-6010 rod, it is easy to use and splatters very little. And E-7018 is harder to use but has a higher strength and makes very nice welds on clean metal.
The 60 and 70 on the rod number is the tensile strength, ie 60,000psi and 70,000 psi. The next letter is the position letter, the 1 means that it is a all position rod and the last number is for the current type, like AC or DC.

6010 is really ugly.
7018 is a lot funner.and better.
With 7018 try to keep your arc gap at a mininum and use a close zig zag pattern, not circles. 6010 use overlapping circles.
