what is the difference between brazing and soldering
Soldering - Soldering has the same definition as brazing except for the fact that the filler metal used has a liquidus below 840Â°F (450Â°C) and below the solidus of the base metals.
Brazing - The AWS defines brazing as a group of joining processes that produce coalescence of materials by heating them to the brazing temperature and by using a filler metal (solder) having a liquidus above 840Â°F (450Â°C), and below the solidus of the base metals.
We can define brazing as the joining of metals through the use of a heat and a filler metal. In this process the melting temperature of the brazing filler metal is above 840Â° F (450Â° C), but in all cases below the melting point of the metals being joined.
