Difference between brazing and welding

Several processes are used to join the different metal parts. Among all of those processes, brazing and welding are used to fill or join or fix in the gaps in metals. These two processes serve the same purpose. However, their modus operandi is different. Both the processes differ in terms of their temperature, base metals and melting point temperature of the filler.

Talking about the welding, it is the most common process that is used to join the two metal pieces and the thermoplastics.  In this process, the base metal is melted along with the filler electrode to form a weld pool of molten metal. This weld pool gets solidified and makes a strong joint. Sometimes pressure can be also applied along with the heat for the welding. Welding also needs a shield that protects the filler metal from getting contaminated or getting oxidized. There is also a solid state welding process – friction welding. It uses the heat generated from friction to weld the metal.

Welding can be performed by using various energy sources like gas flames, laser, electron beam, ultrasound, and friction. This process can be performed under different environmental conditions including underwater, outer space and open air. It is a dangerous process and needs precautions to avoid any electric shock, vision damage or poisonous gas inhalation.
