Solder – an alloy or metal, which is used in soldering, as an intermediate between the metal parts to be connected. In solders always lower melting point than the metals to be joined. The main difference from the brazing welding is a relatively slight heating of metals, which are connected, allowing you not to change the structure of the metal.

Solders are produced in the form of bars, ingots cast, foil, wire, powder, paste (powder and liquid solder flux for soldering) in the middle of the tubes filled with rosin.

Applicable soldering solder alloy., Are very diverse.

Fusible solder – are soft and provide a low mechanical properties (pic-30 pic-18 – lead-tin, POS-40 – tin-lead). In such cases, the flux is used for soldering of zinc chloride and hydrochloric acid, in their absence – 40% aqueous solution of phosphoric acid. Often, in order to facilitate the soldering process, the surface of the pre-Copper.

Classification solders

Regarding melting temperature solders are divided into:

Soft solders – melting point 400 ° C; Hard solders – more than 500 ° C; Semisolid solders – the melting temperature is in the range from melting point of pure tin to 400 ° C. Solders are also distinguished by the mechanical strength.

Distinguished brands such solder: 15-2 Poss, Poss 10-2, 40-2 Poss, Poss 95-5, 25-2 Poss, Poss 35-2, 30-2 Poss, Poss 8-3; Posse 5-1, 18-2 Poss, Poss 4-4, 4-6 Posse and others.

Soft solders have a tensile strength of 16 to 100 MPa, and soldering or brazing is performed by immersion of the parts in the molten solder.

Hard solders have tensile strength – 100-500Mpa and soldering is performed electro-contact manner, copper or graphite electrodes, and fine detail solder blowtorch.

When selecting the composition of solder need to know the type of connected metal, and a method of soldering and thermal constraints on the soldering process, weight and size parameters of soldered elements required corrosion resistance.

Silver solders (PSr40, PSr25, PSr45) have a melting point 605˚ C, 775˚ C and 725˚ C. They are often used for soldering stainless steel. Also for this purpose the silver solders are used with the addition of manganese and nickel (PSr40, PSr50K, PSr44), phosphorus (PSr25F) solder with the addition of 15% manganese and silver-copper solders supplemented with 28% Cu and 72% Ag.

Copper solder composed of pure copper and brass. They are rarely used for soldering stainless steel. Brazing is carried out at a temperature from 1100 do1120˚S prepared in reducing atmospheres, such as hydrogen or dissociated ammonia. In this method, one side of the brazing solder, copper is best applied electrolytically. Pike brass almost no time do not apply, since then often develop cracks.

Nickel-based solders with additions of (Si, B, Zn, Be, Pd, Ge, Mn), which lower the melting point, is used for brazing at high temperatures. The elements other than palladium and manganese form a fragile eutectic. Therefore, these solders are used as pastes and powders and pastes are formulated with organic binder.

Antimony solders used in tinning and soldering circuits, as in the manufacture of light bulbs and electrical industry, in the automotive industry. Also, solder is used for soldering and tinning of sheet packaging, metallized products, ceramic for brazing copper, iron, lead, brass.
