Solder Sheet Metal Into A Cup

With both pieces of metal pre treated the solder will bind much better.

Solder sheet metal into a cup.

Make sure that you add some flux to the area to be soldered. In this case i m soldering a copper reducer to a piece of copper pipe. Apply more heat if the metal cools off. Apply solder at the joint of the 2 metal pieces.

If you re using a soldering iron hold the iron against the joint. If the wire is a very small gauge and will not support itself in the cup fill the cup or cups with solder then grasp the wire to be installed into the cup apply the solder iron to the edge of the cup allowing the solder in the cup to become molten and once molten insert the wire into the solder cup removed the solder iron and hold the wire until the solder solidifies and you should be all set. The body should be long enough to completely encircle the bottom but ensure both the body and base have enough of an overlap for seaming. Do this by pouring the acid into a glass container and adding zinc roofing nails and or slivers of galvanized metal until it no longer bubbles strain the resulting liquid into another glass container.

Touch the solder to the heated metal so it melts. Place the 2 pieces of copper brass you want to solder on a hard surface. Soldering works by capillary action the solder is drawn into the joint by the heat and flux. Only etch the area where solder is wanted or you will end up with an ugly mess of a job.

As for the wire in a cup completely different story as the cup should be sized to the wire being used. Step 1 cut out sheet metal for the body handle wire and a circle for the bottom of the cup. Then spread the solder until you cover the whole joint. View the products.

The accompanying flux acts as a temp. Soldering sheet metal is done by first etching the metal with the appropriate acid for the metal being soldered. The handle need only be a strip of tin long enough for a finger to slip inside when it s shaped.
