Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It is a value-added [ 1 ] process involving the creation of machines, parts, and structures from various raw materials.
Welding is a fabrication 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 that cools to become a strong joint, but sometimes pressure is used in conjunction with heat , or by itself, to produce the weld.
