Soldering and brazing both are metal joining process used in
different joining conditions. These processes are more confusing to differentiate
because both process use filler material and done below critical temperature.
Today I am gaining to tell you difference between soldering and brazing so you
can understand these processes clearly. The basic and main difference between
soldering and brazing is that soldering is used to make a electrically strong
joint between metals which can withstand with all electric loads and brazing is
used to make a mechanical strong joint which can withstand with all mechanic
loads and stresses. These processes can be differentiating in following
aspects.

Soldering
|
Brazing
|
1.
|
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.
|
2.
|
Soldering is done at temperature below 200 C.
|
Brazing is done at temperature above 450C but below the
critical temperature of metal.
|
3.
|
These joints are weaker than brazing joints.
|
It forms stronger joint.
|
4.
|
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.
|
5.
|
It does not need a special training to soldering.
|
It needs special trading.
|
6.
|
It is a cheaper process.
|
It is a costly process.
|
7.
|
Soldering does not need to preheat of base metal.
|
This process needs preheating of base metal.
|
8.
|
It is used to joint electronics component.
|
It is used in automotive industries and pipe fitting.
|
9.
|
This process is very flexible and easy to automate.
|
It is not so easy for automation except automation is done
at automotive industries.

These are the difference between soldering and brazing. If you
have any query asks by comment.
