: What kinda rod?

Me and a friend are going to do some rust repair on my elcamino on the lower quater panels. We will be using a torch and rod. I have a whole bunch or copper core rod (I think its copper), can I use this or do I need another kind. I would like to use what I have it possible if its not going to be a problem. What kind of rod specifically should I NOT use?

Thanks

It's probably not copper, but brass. That sounds like brazing to me. If you tried a carbon steel stick, you'd create so much heat you'd warp the panel for sure. You can use the brass rods, but be warned. As the great Mr. Elmer Fudd would say, 'Be veewy veewy careful'not to heat the metal up and warp it. That's the main reason brazing isn't the best way to go for patching in holes. If you don't have access to a mig welder and you're bound and determined to braze weld, keep the panel cool with lots of cool water. Soaked rags will help. Only do a small spot at a time and rotate weld locations to prevent warping. Cool down between welds.

Good advice Jimmy P, I would seriously consider a MIG over the torch and brass rod. Either way, you still have to go slow, use lots of water, and don't stay in one area too long.

When i first started out I didn't have access to a welder.I brazed patch panels with decent results.You WILL use a lot of filler though.I used stuff called heat fence.Its like a putty that you put around the area to keep the heat from spreading around and warping the panel.I think Eastwood sells it.Some rags soaked with cold water will work too.If you plan on doing a lot of repairs,i would get a mig welder.You can get a decent one for a couple hundred dollars.

Another option would be to do quick runs to get your filler rod into position with your friend working behind you to quench the pannel. After you you have the bulk of the pannel in its final position you can then blend the seams down with the torch.
