Solders are metals or alloys that are used as an intermediate binder to bond parts together. Solders must have a lower melting point than the materials being joined. The advantage of brazing, compared to welding, is that the heating during assembly is insignificant and, therefore, no change in the structure of the parts is possible.
Production
GOST 21 930-76 regulates the production of solders based on tin, antimony and lead, namelyPOSSU 15-2; 5-1; 95-5; 4-6; 40-2; 8-3; 35-2; 30-2; 10-2; 25-2; 18-2; 4-4 and others. They are used for tinning and soldering of parts. Solders are supplied in the form of common cast bars, foil, rods, fluxes, powders, tubes, wires, tapes and also in the form of solder pastes.

The process of choosing the composition of this or that solder should be carried out depending on the soldering method, the type of metals to be joined, the level of temperature limits for the soldering process and subsequent operation, size and weight of the elements to be joined, the required corrosion resistance and other conditions.
