The best types of welds to use for copper are typically TIG (Tungsten Inert Gas) welding or oxy-acetylene welding. These methods allow for precise control and produce high-quality welds on copper.

Expert Answer

A brass welding rod is typically the most effective, as it's specifically designed for joining brass pieces. These rods are made of a similar composition to the brass being welded, ensuring compatibility and a strong bond.

Question

How do I weld a flat copper sheet?

Community Answer

Slow heat with a "soft" flame so you don't blow a hole through it. Brass rod works well for seams.

Question

How do I weld two copper wires together?

Community Answer

Use a little flux and heat both ends of the copper wires just to the melting point, then fuse them. Lead solder usually is used to join copper.

Question

What kind of wire should I use to mig weld?

Community Answer

You should use gold wire because it is the most conductive resource, but it depends on your price range. If you're running a copper weld you could also make your own wire.

Question

If the weld has holes, can I clean oxidation, preheat, and fill the holes for a more consistent finish?

Community Answer

With a stick welder that is going to be real tricky, might be easier in a small forge with perhaps a steel mandrel. Using a smaller mandrel might work better, then use it to slowly stretch the copper back to shape.
