Introduction Solderingis a process in which two or more metal items

are joined together by melting and flowing a filler metal

into the joint, the filler metal having a lower melting point

than the workpiece.

Soldering differs from welding in that the workpieces are

not melted.

Solders

Traditional Solder is an amalgam of Tin and Lead. The

percentage of each of these materials defines the use for the

solder

%Tin %Lead Use

60 40 Good for all electrical and mechanical work

45 55 Very liquid used in plumbing

50 32 Low melt solder for white-metal casings

Applications Soldering was historically used to make jewelry items and

cooking ware .

It is used to connect electrical wiring and to connect

electronic components to printed circuit boards (PCBs).

It is used for connections between copper pipes inplumbing systems as well as joints in sheet metal objects

such as food cans, roof flashing, rain gutters and

automobile radiators.

1. Define about soldering, solder and flux?

2. Draw a rough diagram of soldering tool and write the

name of each part with their material?

3. Describe why after a period of use, the tip of a soldering

iron is not working and how we can solve it?

Dear student Q. 3 was faced by one group during

experimental work so ask with that group or think about it and

than write.
