Ganache soldering is a metal-joining technique used in the production of jewelry and high-precision metal components. As with all types of soldering, it involves the melting of metal and an alloy to form the bonded joint. But in the case of ganache soldering, the bonding is made between a piece of metal and a crystal slice, is much harder than regular soldering. Here are the steps involved in the process.
1.Prepare and clean the surfaces: Before starting to solder a Ganache joint, it is essential to prepare the surfaces to be joined. Start by cleaning both pieces of metal as much as possible. Use a wire brush to remove oxidation, dirt and other contaminants. Use a polisher or an abrasive cloth to smooth the surfaces before joining.
2.Select a suitable flux: The flux is the medium through which the heat is transferred to the metal andcrystal. A good flux that is suited for the metals being joined should be selected for the job. For ganache soldering, a suitable flux would be a high-temperature, zinc-oxide-free flux.
3.Attaching the flux onto the joint: The flux needs to be attached to the joint to be soldered. This is done by pressing a small piece of flux onto the joint. The flux must be applied evenly to ensure a strong bond between the metals and the crystal.
4.Select the right solder: A suitable solder should be selected for the job, depending on the temperature of the joining process. For Ganache soldering, a zinc-free, high-temperature solder is preferred.
5.Heat the joint: Heat the joint using a soldering iron or torch until the solder melts. Care must be taken to ensure that both surfaces being soldered are heated evenly. The temperature should not exceed the melting point of the solder.
6.Solder the joint: Lower the crystal onto the joint and heat it up until the solder melts. Once the solder is melted, the crystal is drawn into the joint and fused with the metals.
7.Tinning the joint: This step is optional, but it helps to fill in any gaps or cavities in the joint. The tinning process is done by applying the solder directly onto the joint and allowing it to melt into the joint.
8.Finishing the process: Once the joint is soldered, it needs to be cleaned and polished. This can be done using a wire brush and an abrasive cloth. Finally, the newly soldered joint can be sealed with a clear coat of lacquer to protect it from oxidation.
Ganache soldering is an intricate and precise method of metal-joining. Although the process is quite delicate and time-consuming, the finished product is usually of superior quality and is superior to regular soldering. This technique is commonly used in the production of jewelry and precision parts, where a strong bond between two pieces of metal and a crystal is required.
