Joining the ends of two wires, rods or groups of wires (1) by fusing, using the application of heat or pressure or both, by means of a flame torch, electric arc or electric current; or (2) by cold pressure.
A joining process that produces merging of materials by heating them to the welding temperature, with or without the application of pressure or by the application of pressure alone, and with or without the use of filler material.
The process of joining metals by fusing them together under direct, intense heat. A commonly used source of heat for welding is an oxyacetylene torch. A metal rod may be applied to the joint which melts into any gaps and strengthens the bond.
Joining thermoplastic pieces by one of several heat-softening processes.
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 buildup of heat in synthetic fabrics to create the bonding.
Joining two or more pieces of material together by the application of heat or pressure, or both, with or without the use of the filler material. The joint is formed either by inter-diffusion across the interface or by localised melting and re-solidification.
fastening two pieces of metal together by softening with heat and applying pressure
Is a process that joins two pieces of metal using very high heat.
The process of permanently joining two or more metal parts, by melting both materials. The molten materials quickly cool, and the two metals are permanently bonded.
the union of pieces of metal made liquid by heating, or by pressure or both; types of welding include arc welding, gas welding, resistance welding, friction welding, plasma welding and electron beam welding
The type of joinery for metal by using heat and flux.
Joining two or more pieces of aluminum by applying heat or pressure, or both, with or without filler metal to produce a localized union through fusion or recrystallization across the interface. (In cold welding, it is a solid state welding process in which pressure is used at room temperature to produce coalescence of metals with substantial deformation at the weld.)
operation of micro-metal industry consisting in executing a melted seam connecting two parts
The process of joining two, or more, pieces of metal together by melting and fusing the parent metal edges together with, or without, filler metal.
Joining two or more pieces of metal by applying heat, pressure, or both, with or without filler material to produce a localized union through fusion or recrystallization across the interface. The thickness of the filler material is much greater than the capillary dimensions encountered in brazing.
the joining of two or more pieces of plastics by fusion of the material in the pieces at adjoining or nearby areas either with or without the addition of plastic form another source.
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.
A metallurgical joining process of metals using diffusion and intermetallic formations.
Welding is a process for joining similar metals. Welding joins metals by melting and fusing the base metals being joined and the filler metal applied. Welding employs pinpointed, localized heat input. Most welding involves ferrous-based metals such as steel and stainless steel. Welding covers a temperature range of 1500° F - 3000° F. Weld joints are usually stronger than, or as strong as, the base metals being joined. Typically, welding is used for forging, blacksmithing, oil pipelines, and food equipment applications. See electrode, MIG, and TIG.
The fusing together of metals by melting the pieces where they meet and will be joined. Use of pressure and/or a filler material may aid in the fusion.
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.
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 (the weld puddle) that cools to become a strong joint, but sometimes pressure is used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the workpieces to form a bond between them, without melting the workpieces.
