welding

Definition von welding im Englisch Englisch wörterbuch: To unite or fuse, as pieces of metal, by hammering, compressing, or the like, especially after rendering soft or pasty by heat, and sometimes with the addition of fusible material like or unlike the pieces to be united; 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; A process of joining similar metals by heating them so that they melt into one another Compare to brazing; A process of joining metals by heating until they are fused together, or by heating and applying pressure until there is a plastic joining action Filler metal may or may not be used; The joining of thermoplastics materials by one of several softening process-hot-gas torch, heated rollers or strips, friction or high-frequency heating; Technique for joining metallic parts, usually through the application of heat. Discovered in the 1st millennium AD during attempts to manipulate iron into useful shapes, the technique produced a strong, tough blade. Welding traditionally involved interlayering relatively soft and tough iron with high-carbon material, followed by hammer forging. Modern welding processes include gas welding, arc welding, and resistance welding. More recently, electron-beam welding, laser welding, and several solid-phase processes such as diffusion bonding, friction welding, and ultrasonic joining have been developed. See also brazing, soldering; A method of manufacture or repair involving joining two pieces of metal or plastic by fusion. Heat is normaly used such as an open flame (i.e. acetylene, propane or butane), laser light or electric arc, and the fusion may be autogenous or with the addition of a similar substance to the weld pool; fastening two pieces of metal together by softening with heat and applying pressure; 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 together and heated simultaneously, so that recrystallization occurs across the interface Joining two or more pieces of material by applying heat or pressure, or both, with or without filler metal, to produce a loxalized union through fusion or recrystallization across the interface; 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; {i} something welded; act of uniting pieces of metal through heat; the joining of two metal surfaces that have been heated, melted, and fused together

Gas tungsten arc welding: (Mühendislik) Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma
Shielded metal arc welding: (Mühendislik) Shielded metal arc welding (SMAW), also known as manual metal arc (MMA) welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode coated in flux to lay the weld. An electric current, in the form of either alternating current or direct current from a welding power supply, is used to form an electric arc between the electrode and the metals to be joined. As the weld is laid, the flux coating of the electrode disintegrates, giving off vapors that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination
Submerged Arc Welding: (Mühendislik) Submerged Arc Welding (SAW) is a common arc welding process. It requires a continuously fed consumable solid or tubular (flux cored) electrode. The molten weld and the arc zone are protected from atmospheric contamination by being “submerged” under a blanket of granular fusible flux. When molten, the flux becomes conductive, and provides a current path between the electrode and the work
electroslag welding: (Metal İşleme) (metallurgy) A welding process in which consumable electrodes are fed into a joint containing flux; the current melts the flux, and the flux in turn melts the faces of the joint and the electrodes, allowing the weld metal to form a continuously cast ingot between the joint faces
gas metal arc welding: (Mühendislik) Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun. A constant voltage, direct current power source is most commonly used with GMAW, but constant current systems, as well as alternating current, can be used. There are four primary methods of metal transfer in GMAW, called globular, short-circuiting, spray, and pulsed-spray, each of which has distinct properties and corresponding advantages and limitations
