I've only recently started using gas welding where in the past I used
brazing, silver soldering, and MIG depending on application. MIG can add a
considerable amount of metal (relatively speaking, that is) that can often
necessitate grinding away the excess. Brazing and silver soldering "flow"
under, in, and around the joints and can leave a nice smooth transition
that needs little or no smoothing. But, there is that distinct difference
in metal that is easily seen. Not a problem if you are painting over the
piece, but if you are wanting a waxed wrought iron (i.e. you want the fire
scale to determine the color/patina), the silver or brass brazing material
will stand out like a sore thumb.
I'm finding that gas welding lets me use the same steel for filler
material as the piece I'm welding is made out of. It doesn't flow like
braze or solder (spelter?), but you can control the amount of filler
material used almost like solder and much more controlled than with MIG or
stick. You can "push" the puddle around and with practice (more than I
have to date) produce a pretty smooth transition with plenty of penetration
(much better than MIG) and minimal, if any, grinding/sanding the transition
area.
TIG, from all I've heard but never tried, is the best of all.
