PROCEDURE OF HARD SOLDERING WITH SILVER COATED WIRE
This procedure is used for soldering copper, steel, brass, copper alloys, nickel, etc.../p>
The PROCEDURE is as follows:/strong>
- The surface of the material must be cleaned of oxidation.
- The cleaning itself depends on the materials, so copper and brass are cleaned with acids (preferably with hydrochloric acid) or cleaning pastes.li>Acetylene and oxygen gases are most often used to heat the materials to be soldered.i>
- Heating is done using burners that are selected depending on the thickness of the material to be soldered./li>
- The material is heated to a temperature of 600-750*C.
- When the material is heated (the surface turns red), the wire is added to the heated place and spilled.
- During the soldering process with brass wire, BORAX powder is added.
- With light circular and straight movements of the torch, the silver solder is spread to the desired width.i>
- The process of soldering with silver wire gives a finer and cleaner weld than soldering with brass wire and BORAX powder
- After cooling the soldered piece, we clean it with a wire brush (brass or stainless steel brush) or with an arci cloth.
