Advantages & Disadvantages of Brazing.

Advantages & Disadvantages of Brazing.

Definition of Brazing: Brazing is a metal-joining process whereby a filler metal is heated above melting point and distributed between two or more close-fitting parts bycapillary action. The filler metal is brought slightly above its melting (liquidus) temperature while protected by a suitable atmosphere, usually a flux. It then flows over the base metal (known as wetting) and is then […]

What is Welding? Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which […]
