The basic difference between soldering and brazing is the temperature necessary to melt the filler metal. That temperature is defined to be 842ºF/450ºC by the American Welding Society (AWS) but is often rounded to 840ºF. If the filler metal melts below 840ºF the process being performed is soldering.
For many years the two most common methods of joining copper tube and fittings have been soldering and brazing. These tried and true methods are in a number of ways similar, yet there are also several distinct differences that set them apart. This paper explains the similarities and highlights the differences between the two joining processes to help determine which joining method is most desirable.
Overview
The most common method of joining copper tube is with the use of a socket-type, copper or copper alloy fitting into which the tube sections are inserted and fastened by means of a filler metal, using either a soldering or brazing process. This type of joint is known as a capillary or lap joint because the socket of the fitting overlaps the tube end and a space is formed between the tube and the fitting. This space is called the capillary space. The surfaces of fitting and tube that overlap to form the joint are known as the faying surfaces. Tube and fitting are then solidly joined using a filler metal that is melted into the capillary space and adheres to these surfaces.

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 going 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.
