I have my 66 Dart in a local body shop. They are a large shop (for my area) and keep up with technology. Brian the guy that has been working on the car kept talking about brazing the lower 1/4 patch panels on. Even though I have been a Tool dealer for 28 years I had never heard of the technology. It's a specific wire welder that uses brass wire and inert gas (not for sure what) to weld panels. I believe it's silicone bronze welding. Apparently the OEM is using it in different places. It doesn't take a ton of heat to melt and is quite fast to lay down a bead. (time is money compared to steel wire weld). Dang it grinds smooth easy too. They panel bonded most of the metal to metal seams, spot welded what they could get to and wire braised the rest. They then used a fiberglass type filler and then regular filler as a top coat. (so far) I got my quarter patch panels through Here's a start to present photo shoot. Silicon Bronze MIG Brazing Basics - MillerWelds

sounds perfect for sheet metal body work as well as dissimilar metals. wonder if all gas migs can adapt to it?
 
Sure is green. Was the norm when i learned to weld panels on. Brass was popular.
 
Just messaged my buddy/parts supplier. Hes going to look into it and find me some wire to try. The dart is going to need a lot of patching.

Toolman, yours is coming along nicely. Its awesome the body shop lets you in to visit, take photos and vids. Im the go to tech for my local body shop,do the mech and diagnostic work for them.
 
I have read that this works good with TIG.
I plan to try that on some pinhole rust.
It seems like a good idea because of the different thickness of metal on that problem area.
It would have a tendency to blow through if I was melting the base metal.
This would save the a lot of original metal if I was successful
But I had not seen the MIG being used.

Reports on web are both gases seems to work.

An episode of "how it's made" showed Rolls Royce being built. They use the same/ similar process to fasten the roof panel/ etc to the car
 
Before the advent of mig welding, brazing with a gas welder was common .One disadvantage was that it would not withstand a whole lot of vibration so was used carefully on body panels. On another note, I knew a fellow who built a nice set of headers for a Dodge 6 cylinder using brass welding on the pipe. They lasted about 20 miles before everything let go! Heat was the culprit here.
 
Like #5, brazing with a torch and Flux is straightforward and works beautifully to fill holes, add patches or panels, etc. The brass flows out nicely with a torch. The lower heat minimizes distortion of large panels.
Any advantage with wire feed?
