Soft Soldering and Its Glossary of Terms

Soft soldering is the process of joining metal parts by heating and running a low-melting point alloy between the two surfaces being joined. As cooling takes place, the alloy solidifies and results in a secure joint.  For most purposes, the low- melting point solder alloy is a composition of lead and tin.  Solder melts at a temperature less than 3000C, which is far below the melting temperature of the metal being joined and produces a low strength joint. Soft soldering is used extensively in sheet metal work for joining parts…

Flux Used in Soft Soldering

The operation of brazing, soldering and welding has brought out the use of fluxes in service. Flux is a chemical substance, which is made for cleaning the surface of the job and preventing oxidation in operations, such as welding, soldering and brazing. It is rather difficult to have satisfactorily brazed or soldered joints without the use of fluxes. Therefore it is very essential to use flux in soldering, brazing and welding. Soldering flux may be defined as a substance (solid or liquid) applied to a metal to make solder flow…

Soldering, Welding and Brazing Carried Out in Workshop

In engineering, while manufacturing or assembling different parts or jobs, two or more metal pieces are joined together to form a complete job or assembly. There are several methods by which two or more metal parts can be joined. Joints can be made by riveting, welding, soldering, brazing, grooving and making some other type of seams. Soldering – Soldering is the method of joining two or more pieces of metal by means of a low melting fusible alloy (solder), which is applied in the molten state. Types of Soldering –…
