When doing soldering, you use a soldering iron stand to prevent accidental damage. The temperature of soldering irons can reach 800 F (Fahrenheit), so it is very important to know where your iron is at all times.

The clips will help you to hold the things that you are trying to solder while using the soldering iron and solder. It is a device consisting of 2 or more clips and sometimes a magnifying glass/light is attached. Once both materials are sufficiently heated, you can then set the soldering metal between them which melts and acts as a bonding agent. However, it is similar to hard soldering, the metal being bonded is heated as opposed to melting. These types of soldering metal use a very higher melting point than the metals used in hard and soft soldering. Electrician’s solder-lead 58%, tin 42%.The different compositions of solder for different purposes are as follows: In hard soldering, a blowtorch constitutes the equipment. The fluxes are mostly in paste form and are applied to the joint with a brush before heating. The temperatures of the various hard solder vary from about 600 to 900°. Silver soldering is a hard soldering method, and silver mixed with tin is utilised as a solder. It employs solder which metal at higher temperatures and are stronger than those used in soft soldering. The soft soldering has the lowest filler metal melting point of all soldering types, which is less than about 400☌, these filler metals are typically alloys, often with liquid temperatures below 350☌.ĭue to the low temperatures used in soft soldering, it thermally stresses components the least, but does not create strong joints and is therefore unsuitable for mechanical load-bearing applications. A blow torch or soldering iron is made, a device for heating base metals and melting solder and flux. The resin is non-corrosive, but it does not have the cleaning properties of zinc chloride. Although corrosive, Zinc chloride is the most common soldering flux. Its function is to prevent oxidation of the surfaces to be soldered or to dissolve oxides that settled on the metal surfaces during the healing process. A suitable flux is always used in soft soldering. The solder, which is mostly composed of lead and tin, has a melting range of 150 to 350☌. Soft soldering is also used for joining wires and small components. It is used in sheet-metal work for joining parts that are not exposed to high temperatures and are not subjected to extreme loads and forces.

The strength of the soldering joint is relatively low. After soldering, the residues of flux should be removed by washing thoroughly with water to avoid corrosion. The strength of the soldering joint depends upon the strength of the alloys and its adhesive qualities.
