Mounting is the connection of parts of various jewelry that are made by cutting, sawing, milling, stamping and other methods. Such a connection is made by soldering, welding, riveting and other technological operations.

Soldering is considered the most important operation. Soldering is a process in which solid metal parts, cleared of dirt, fats and oxides, are joined using a molten binder metal or alloy - solder, which has a lower temperature in relation to the base metal being fused.

During soldering, processes of mutual dissolution and diffusion occur between the molten solder and the base metal at a shallow depth, resulting in a strong connection of the parts upon solidification.

After soldering, the joints are cleaned very carefully. The cleaner the surfaces being joined, the higher the quality of the soldering. It is important that the solder does not differ in color from the color of the product.
