Flux on copper sheet.

Copper may be welded with a slightly oxidizing flame because the molten metal is protected by the oxide which is formed by the flame. Place the 2 pieces of copper brass you want to solder on a hard surface. Do not attempt to re solder a broken seam. A copper pipe is one of the most common materials used to distribute water throughout the home and copper pipes are typically joined to one another using flux and solder.

30 is mild enough to use with electronic and electrical components. If a solder joint has been broken moisture and dirt will enter inside over time. In the soldering process heat is applied to the copper joint where the pipe and fitting meet and the gap between the joint is filled with molten metal. This is due to the fact that pre tinning your sheets before lapping actually will allow 4 layers of copper to have solder flow while generally the flux alone will only draw flux to adhere to 2 layers.

All post solder residues are water soluble and must be cleaned off with 60 c 140 f water to avoid cleanliness failures. Oxygen free copper deoxidized copper rod should be used rather than oxygen bearing copper for gas welded assemblies. Make sure that you add some flux to the area to be soldered. 30 is a liquid flux that is ideal for soldering copper or brass.

I use a paste flux which is self cleaning although you should still wipe it with some isopropyl alcohol afterwards. 30 is safer to use than the typical inorganic acid soldering flux. If a flux is used to protect the molten metal the flame should be neutral.
