welding

welding
the process of joining together two pieces of metal so that bonding accompanied by appreciable interatomic penetration takes place at their original boundary surfaces. The boundaries more or less disappear at the weld, and integrating crystals develop across them. Welding is carried out by the use of heat or pressure or both and with or without added metal. There are many types of welding including metal arc, atomic hydrogen, submerged arc, resistance butt, flash, spot, stitch, stud and projection.
