Differentiate between soldering and brazing

2 Answers

Answer :

Soldering
Brazing
It is used in electrical industries to joint capacitor, resistor, wire etc. to the electronic plate.
It is used to mechanical industries to joint different metals.
Soldering is done at temperature below 200 C. 
Brazing is done at temperature above 450C but below the critical temperature of metal.
These joints are weaker than brazing joints.
It forms stronger joint.
In soldering an alloy of lead and tin is used known as solder.
In brazing an alloy of copper and zinc is used as filler metal.
It does not need a special training to soldering.
It needs special trading.
It is a cheaper process.
It is a costly process.
Soldering does not need to preheat of base metal.
This process needs preheating of base metal.
It is used to joint electronics component.
It is used in automotive industries and pipe fitting.
This process is very flexible and easy to automate.
It is not so easy for automation except automation is done at automotive industries.
