Submerged arc welding SAW is a common arc welding process The first SAW patent was taken out in The process requires a continuously fed consumable solid or tubular metal cored electrode The molten weld and the arc zone are protected from atmospheric contamination by being " submerged" under a blanket of granular fusible flux Aug 09 other devices or methods but only when it is clearly evident tllat an equivalent degree of protection is tllereby secured To secure uniform application and of tllis Standard administrative or regulatory authorities are urged to consult the B30 Committee in accordanceArc Welding Welding processes which use heat from the resistance of current flow and arc rays to produce coalescence of metals Can use either direct DC or alternating AC current consumable or non consumable electrodes with or without the application of pressure Arc welding electrode Arc welding is a method of joining two pieces of metal into one solid piece To do this the heat of an electric arc is concentrated on the edges of two pieces of metal to be joined The metal melts while the edges are still molten additional melted metal is added A Guide to Scaffold Use in the Construction Industry Small Business Safety Management Series U S Department of Labor Occupational Safety and Health AdministrationJun 28 Worlds largest machinist CNC and manufacturing forum With more than 10 6 million unique visitors over the last year Practical Machinist is the most visited site for metalworking professionals It feeds flux and filler metal to the welding joint Electrode filler metal gets energized here It stores the flux and controls the rate of flux deposition on the welding joint The granulated flux shields and thus protects molten weld from atmospheric contamination The flux cleans weld metal and can also modify its chemical composition This is a list of welding processes separated into their respective associated N reference numbers second column are specified in ISO in the European Union published as EN ISO
