Silver Soldering Copper Sheet

Silver soldering is the process of permanently joining two pieces of metal together using heat to melt pieces of silver solder which melt to fill a prepared joint.

Silver soldering copper sheet. Occasionally touch the silver solder to the juncture of the fitting and the pipe. As such the filler metals for soldering and brazing copper and copper alloy tube and fittings must have melting temperatures below this temperature. It is used essentially with silver for jewellery making and silversmithing but can also be used to join together copper gilding metal brass and gold if needs be. Here s a great trick for making perfectly invisible seams and hiding the solder when soldering copper with silver solder.

Insert the pipe into the fitting. Place your silver sheet to one side and apply a small amount of flux to the top side of your copper sheet. Light the torch and heat the fitting evenly. Melt some solder onto the non steel metal if you re using one.

Copper tubing typically comes in 3 4 inch and 1 2 inch diameters. If you re binding a different metal to the steel like copper or tin pre treat the surface by melting some solder onto it. Originally published in lapidary. Make sure the area that is covered is roughly the same as the size of your silver sheet.

If it begins to melt continue applying solder around the entire joint. Silver solder can be used to join most common metals including mild steel stainless steel copper brass cast iron and dissimilar metals. This gives the steel a surface to bind to. Silver soldering also known as hard soldering or silver brazing also has a higher melting point then lead so it is important to heat up the copper brass sufficiently to get the solder to melt into the joint.

Hardly a week goes by that i don t get asked how to solder copper or other alternative metals like brass and bronze to each other or silver. Even though copper and brass solders wire and paste do exist they re not always on hand. More on this later. Heat up the metal with your soldering iron or torch until it s hot enough to melt solder.

These are available with either 2 or 5 silver and are used primarily for joining copper to copper where if the metal is clean no flux need be used. Once the flux is applied you can place the silver sheet on top of the copper sheet ensuring that the solder is face down on the copper sheet. The melting point of copper cu alloy uns c12200 is 1 981 f 1082 c.
