... Abstract Arc welding applies to a large and diversified group of welding processes that use an electric arc as the source of heat to melt and join metals. This chapter provides a detailed overview of specific arc welding methods: shielded metal arc welding, flux cored arc welding, submerged arc...

... completely uncontaminated surfaces are produced and then brought into contact with each other. In processes of the first group, a third metal or alloy of comparatively low melting point is melted and caused, often with the assistance of a flux, to wet the surfaces to be joined; these are known as brazing...

Greater skill is needed to control the more rapid fluctuations in arc processes. The weld pool created by the high-heat-intensity processes, such as laser beam and electron beam welding...

... avoided; otherwise, the full benefit of the inert gas shielding may be lost. Submerged arc welding (SAW) employs a consumable electrode immersed in a conductive flux that acts as a protective shield from the atmosphere. The arc is struck through the flux, and gravity deposits the molten metal to the...
