Welding bracket on copper radiator

[z302]

The mounting flange on the side of my 69 Camaro has detached itself from the radiator. Has anyone out there had any experience re-attaching the flange? Can it be welded? The bracket is steel and the side tank of the radiator is copper. Thanks for any help that might be out there.

It's soldered on. There's a dimple or raised place on each side plate at the tank. hook a light spring, or bungee cord in each of these (use a piece of wire on the side that's loose, so the bungee cord doesn't melt) this will pull the sides together as the solder melts it'll settle right into the right position then heat the side that is loose with a torch. You may need to add a little solder, but there's usually enough to reattach the side already there.
If it's been broken a while, or it's dirty, you may need to pull the side back a little, clean & re-tin both pieces, then re-solder as above...

Cya,

I believe you will want to use silver solder.
