· The main difference between brazing and welding is that brazing does not involve melting the workpieces together. Also, the heat source is what differentiates the two processes apart from each other. Brazing is applied using a torch, induction, furnace, or dipped at a temperature above 840°F (450°C). On the other hand, welding uses ...

As the brazing alloy filler metal becomes liquid, a pulling force draws the molten brazing alloy between the surfaces of the parent metals.
4. Hot rodding is a technique in which a warm brazing rod is dipped into flux powder and the flux adhering to the rod is transferred to the joint area. This is an effective fluxing method but difficult to achieve good penetration of capillary joints. A refinement on this technique is the use of flux coated brazing rods.
