Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics , by causing fusion , which is distinct from lower temperature metal-joining techniques such as brazing and soldering , which do not melt the base metal. In addition to melting the base metal, a filler material is often added to the joint to form a pool of molten material (the weld pool ) that cools to form a joint that can be as strong as the base material. Pressure may also be used in conjunction with hea
Although less common, there are also solid state welding processes such as friction welding or shielded active gas welding in which metal does not melt.
Some of the best known welding methods include:
