2. What is a Soldering ?? The process of joining two parts / pieces / wires of similar or dissimilar metal by employing a third metal by the application of heat is called Soldering. The third metal is called filler metal while the metal of parts / pieces / wires is called base metal. The melting point of filler metal should be lower than that of the base metal. The filler metal is an alloy of two-three metals.

3. Importance of Soldering : It provides stability to a joint and allows maximum flow of current (100%) through for the same. For, some purposes, such as joining of armature coils leads to the commentator segments and preparing an electronic circuit on a PCB etc. Soldering is the only convenient process.

4. What are the Different Soldering Techniques ?? Basic two types: Soldering Hard Solder Soft Solder S pelter Silver Solder

5. Hard Solder : It is used for joining large size parts of Copper, Brass, Iron, etc. and heavy cable wires. It has two types: a) Spelter : It is used in plumber and sheet-metal work. Its composition may be any of the following: b) Silver Solder : its melting point is lower than that of the spelter. it is used for joining part of Gold, Silver, German-Silver etc. Its composition may be as follows: Copper=50%, Zinc=50% Copper=67%, Zinc=33% Copper=50%, Zinc=37%, Tin=13% For silver items Copper=33%, Silver=67% For Gold jewellery Copper=20%, Zinc=10%, gold=70% For silver jewellery Copper=20%, Silver=70%, Zinc=10% For German-silver items Copper=35%, Zinc=55%, Nickel=10%

6. Soft Solder : It is used in electrical and electronic works. Its melting point is lower than that of silver solder even. Its constituents are Tin and Lead. Higher is the percentage of Tin in the solder, lower will be its melting point. For electrical jobs : 50% : 50% or 66% : 34% solder is suitable. For electronics jobs : 80% : 20% solder is suitable.

7. Basic Soldering Equipments : The basic types as shown: The PCB (Printed Circuit Board ) Soldering Iron Solder Flux Soldering Iron Stand Soldering Wire Basic Equipments

8. Soldering Iron : It is a handheld tool that provides the heat source needed to melt the solder. These tools are typically pencil-like in shape and consist of several different parts that work together to form a comfortable.

9. Soldering Wire : It is comprised of different alloys, or of pure Tin. Each metal requires a certain type of soldering wire to create strong bonds, because the combinations of metals that comprise soldering wire melt at different temperatures

10. Soldering Iron Stand : It helps prevent burns the safest place to keep your soldering iron. The sponge, when moistened, keeps the iron tip clean and removes excess solder.

11. Solder Flux : It is a purifying agent. It is used for easy soldering. it helps as follows: It stops oxidation of the base metal. It helps in the easy flow of molten solder on the base metal. It cleans the joint. It helps in transferring heat quickly to the job.

12. The PCB (Printed Circuit Board) : The PCB is your circuit board. All the soldering you’ll do will take place on the surface of this board.
