Soldering
•^
Soldering:
A joining process by which a
joint is produced by heating, generallybelow 800°F and using a nonferrous fillermetal that has a melting point below thatof the base metals. The filler metal isdistributed between the properly fittedparts by capillary attraction.
Application of Soldering
- Assembling electronic components• Jewelry• Automobile radiator etc
Soldering Application in Electronics
Soldering Equipments
- Soldering Iron• Solder• Flux• Nasal pliers

Solders
- Common solder alloys are mixtures of tin
and lead, respectively:
- 63/37: melts at 183 °C (361 °F)• 60/40: melts between 183–190 °C (361–
374 °F)
50/50: melts between 185–215 °C (365–419 °F)
Brazing
- Brazing is a joining process that is
identical to soldering except that thejoining takes place at temperatures above840 °F. The filler metal is distributedbetween closely fitted surfaces of the jointby capillary attraction.
- Brazed joints are usually stronger than
soldered joints.
Braze
- A braze is a joint produced by heating an
assembly to suitable temperatures and byusing a filler metal having a liquidus above450 °C (840 °F) and below the solidus ofthe base metals. The filler metal isdistributed between the closely fittedsurfaces of the joint by capillary attraction.
