The Sources of Oxygen and Nitrogen Contamination in Submerged Arc Welding Using CaO-Al Based Fluxes Flux composition plays a major role in oxygen contamination but is insignificant for nitrogen pickup BY T. LAU, G. C. WEATHERLY AND A. MC LEAN ABSTRACT. A study of the sources of oxygen and nitrogen contamination durFile Size: KB. A welding flux could be applied by pouring it over the weld pool in a granular form as in submerged arc welding process, it can also be coated on the exterior of the bare electrode as is the case of shielded arc welding or the flux could be placed in the interior core of the electrode as is the case of flux core arc welding. The molten weld and the arc zone are protected from atmospheric contamination by being "submerged" under a blanket of granular fusible flux consisting of lime, silica, manganese oxide, calcium fluoride, and other compounds. When molten, the flux becomes conductive, and provides a current path between the electrode and the work. Submerged arc welding is an ‘Arc Welding’ process in which the arc is concealed by a blanket of granular and fusible flux [, 37]. Heat for SAW is generated by an arc between a bare, solid metal (or cored) consumable-wire or strip electrode and the work-piece. The arc is File Size: KB.
Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing g is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.. In addition to melting the base metal, a filler . source or Arc welding power source and the work piece. This process is referred to as Arc welding or Arc cutting and can produce heat at temperatures over с. Arc welding can be used on a wide range of different metals, alloys and materials. Dependent on the process and welding result required Arc welding.

Oxy Acetylene welding is a welding process manually, in which the surfaces to be joined, which is warming to melt by a gas flame Oxyacetylene with or without filler metal, where the connection process without emphasis. In addition to the purposes of welding (connecting), gas welding can also be used as preheating, brazing, cutting, and hard facing.

Gas Metal Arc Welding (GMAW), by definition, is an arc welding process which produces the coalescence of metals by heating them with an arc between a con-tinuously fed filler metal electrode and the work. The process uses shielding from an externally supplied gas to protect the molten weld pool.
