Soldering is a process in which two or more items are joined together by melting and putting a non-ferrous filler metal (solder) into the joint at a temperature below 430 °C (800°F).

 In brazing, the parent metals also do not melt, but the filler metal is the one that melts at a higher temperature, above 430 °C (800°F), in contrast to the soldering process.

 That's what differentiates SOLDERING from BRAZING. 

Soldering and brazing are preferred to welding when it comes to high production rates, multi-joints, complex forms and aesthetic parts usually on non-ferrous materials. Both processes produce strong, sealed and leak-proof joints. 

Soldering and brazing use filler metals in solid forms (such as rings, shims, rods, wires...) as well as in paste forms. A proper brazed joint begins with a good joint design. 

The soldering and brazing processes can employ various heat sources such as flame, induction, resistance, furnace, and vacuum.

You will need to use a flux to remove and prevent the reformulation of surface oxides on the base metals. The fluxes themselves are not easily removed. This is the difference between the CORROSIVE, INTERMEDIATE AND NON-CORROSIVE

Different specifications need to be met such as electrical conductivity, corrosion resistance, pressure tightness, mechanical performance, and temperature sustainability.
