Comprehensive Analysis

1) "Welding" -- As to welding flux 1weld Pronunciation: 'weld Function: verb Etymology: alteration of obsolete English well to weld, from Middle English wellen to boil, well, weld -- more at WELL intransitive verb : to become or be capable of being welded transitive verb 1 a : to unite (metallic parts) by heating and allowing the metals to flow together or by hammering or compressing with or without previous heating b : to unite (plastics) in a similar manner by heating c : to repair (as an article) by this method d : to produce or create as if by such a process 2 : to unite or reunite closely or intimately <architecture that welds the past and the present> - weld·able /'wel-d&-b&l/ adjective Pronunciation Symbols 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. Arc welding Many different energy sources can be used for welding, including a gas flame, an electric arc, a laser, an electron beam, friction, and ultrasound. While often an industrial process, welding can be done in many different environments, including open air, underwater and in space. Regardless of location, however, welding remains dangerous, and precautions must be taken to avoid burns, electric shock, poisonous fumes, and overexposure to ultraviolet light. Until the end of the 19th century, the only welding process was forge welding, which blacksmiths had used for centuries to join metals by heating and pounding them. Arc welding and oxyfuel welding were among the first processes to develop late in the century, and resistance welding followed soon after. Welding technology advanced quickly during the early 20th century as World War I and World War II drove the demand for reliable and inexpensive joining methods. Following the wars, several modern welding techniques were developed, including manual methods like shielded metal arc welding, now one of the most popular welding methods, as well as semi-automatic and automatic processes such as gas metal arc welding, submerged arc welding and flux-cored arc welding. Developments continued with the invention of laser beam welding and electron beam welding in the latter half of the century. Today, the science continues to advance. Robot welding is becoming more commonplace in industrial settings, and researchers continue to develop new welding methods and gain greater understanding of weld quality and propertie..." 2) "Flux" -- As to welding flux 1flux Pronunciation: 'fl&ks Function: noun Etymology: Middle English, from Anglo-French & Medieval Latin; Anglo-French, from Medieval Latin fluxus, from Latin, flow, from fluere to flow -- more at FLUID 1 : a flowing of fluid from the body: as a : DIARRHEA b : DYSENTERY 2 : a continuous moving on or passing by (as of a stream) 3 : a continued flow : FLOOD 4 a : INFLUX b : CHANGE, FLUCTUATION <in a state of flux> 5 : a substance used to promote fusion (as of metals or minerals); especially : one (as rosin) applied to surfaces to be joined by soldering, brazing, or welding to clean and free them from oxide and promote their union 6 : the rate of transfer of fluid, particles, or energy across a given surface Pronunciation Symbols In the various subfields of physics, there exist two common usages of the term flux, both with rigorous mathematical frameworks. In the study of transport phenomena (heat transfer, mass transfer and fluid dynamics), flux is defined as the amount that flows through a unit area per unit time, the volumetric flow rate[1]. Flux in this definition is a vector. In the field of electromagnetism, flux is usually the integral of a vector quantity over a finite surface. The result of this integration is a scalar quantity[2]. The magnetic flux is thus the integral of the magnetic vector field over a surface, and the electric flux is defined similarly. Using this definition, the flux of the Poynting vector over a specified surface is the rate at which electromagnetic energy flows through that surface. Confusingly, the Poynting vector is sometimes called the power flux, which is an example of the first usage of flux, above[3]. It has units of watts per square metre (W/m2) One could argue, based on the work of James Clerk Maxwell [4] that the transport definition precedes the more recent way the term is used in electromagnetism. The specific quote from Maxwell is "In the case of fluxes, we have to take the integral, over a surface, of the flux through every element of the surface. The result of this operation is called the surface integral of the flux. It represents the quantity which passes through the surface". In addition to these common mathematically defined definitions, there are many more loose usages found in fields such as biology. 1 Transport phenomena 1.1 Flux definition and theorems 1.2 Chemical diffusion 1.3 Quantum mechanics 2 Electromagnetism 2.1 Flux definition and theorems Further Data On Term for welding flux Internet users who seek welding flux often also seach for: miller welding machines, miller, welding, machine, welding, flux, welding, flux, flux, welding, flux, welding, welding, apron, fusion, welding, tig, welding, aluminum, oxyacetylene, welding, welding, stainless, steel, miller, welding, machines Regularly Occuring Typos with welding flux include: ewlding wleding wedling welidng weldnig weldign elding wlding weding weling weldng weldig weldin qelding selding eelding wwlding wslding wdlding wrlding walding wilding wolding wulding wekding weoding wepding welsing welxing welcing welfing weleing welting weldung weldkng weldong weldang weldeng weldung weldibg weldihg weldijg weldimg weldint weldinf weldinv weldinb weldinh weldinj lfux fulx flxu lux fux flx flu rlux dlux clux vlux glux fkux foux fpux flyx fljx flix flax flex flox fluz flus flud fluc Commonly appearing connections are : west plains missouri, west monroe louisiana, west linn oregon, west islip, west frankfort illinois, west cost choppers, west bloomfield michigan, wenzel sleeping bag, wells beach maine, wells beach, wellborn forest, weight set, weigher, wedge espadrilles, wedding suits, wedding portrait, wedding cards, weblogic portal, web sling, web master, web cameras, weaver grand slam Similar searches have yielded these phrases welding flux: miller welding machine, welding flux, welding flux, flux welding, flux welding, welding apron, fusion welding, tig welding aluminum, oxyacetylene welding, welding stainless steel Certain copy here welding flux made available through Wikipedia and the GNU Free Documentation License.
