The Difference Between Soldering and Brazing
Soldering involves fusing a joining alloy in-between metal parts that are being joined. If the surfaces are smooth, contacts are made, and the joining alloy is mixed into each surface, creating a joint that hardens upon cooling.
Induction soldering has proven a valuable aid to joining processes for many reasons. Among them are fast heating and accurate control of the heat. Rapid heating and precision heat control provide localized heating capability to bond higher-strength components, requiring minimum thinning.
Brazing involves generating heat inside a part, unlike furnaces or flame heating, in which only the surface is heated by convection. The preciseness of brazing allows for the heating of small sections of parts. With both brazing and soldering, a filler metal is used with a melting temperature lower than the solder of the joined metal parts. The coil creates a magnetic field that heats the base material, melting the filler metal.
