Welding vs. Brazing

Weldingnoun

The action or process of welding:

Weldingnoun

joining two materials (especially two metals) together by applying heat, pressure and filler, either separately or in any combination, or

Weldingnoun

binding together inseparably; uniting closely or intimately.

Weldingnoun

fastening two pieces of metal together by softening with heat and applying pressure

Welding

Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion. Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.

Brazingnoun

A method of joining metals by using heat and a filler

Brazing

Brazing is a metal-joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, with the filler metal having a lower melting point than the adjoining metal. Brazing differs from welding in that it does not involve melting the work pieces and from soldering in using higher temperatures for a similar process, while also requiring much more closely fitted parts than when soldering.
