Welding is a fabrication or sculptural 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 (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by ...

an operation by which two or more parts of an assembly are united by means of heat or pressure or both in such a way that there is continuity of the nature of the materials to be joined (e.g. metals or plastics, etc.), either with or without a filler material having a melting temperature that is of the same order as that of the parent material NOTE...

There are two basic methods for applying bonding or welded seams. The first method uses an adhesive film, and the application of heat to glue or laminate two substrates together. The second method involves gluing or attaching two fabrics, using ultrasonic technology. The creation and channeling of high frequency vibratory waves cause a rapid buildu...

A process used to join metals by the application of heat. Fusion welding, which includes gas, arc, and resistance welding, requires that the parent metals be melted. This distinguishes fusion welding from brazing. In pressure welding joining is accomplished by the use of heat and pressure without melting. The parts that are being welded are pressed...

Joining thermoplastic pieces by one of several heat-softening processes. In hot-gas welding, the material is heated by a jet of hot air or inert gas directed from a welding ?torch? onto the area of contact of the surfaces which are being welded. Welding operations to which this method is applied normally require the use of a filler rod. In Spin-Wel...

Welding is the process of joining two pieces of metal together by hammering, pressure or fusion. Filler metal may or may not be used.The thickness of the filler material is much greater than the capillary dimensions encountered in brazing. The filler material has a melting point approximately the same or below that of the base metals, but always ab...

A process by which two materials; either metals, thermoplastics, or some other material, is joined. Basically, localized melting takes place between the two materials and a filler material such as welding wire, which cools and forms a high strength joint (if the process was done correctly).

Welding consists of heating metal on two adjacent plates and then adding new welded metal between them to make a molten pool; when cooled the pool becomes solid and a strong bond is made. A fillet weld is a weld made in an angle between two plates. A butt weld is made when two plates are end to end, with a gap between them, and the whole gap is fil...
