The welder must, in addition to mastering the skill and technique, comply with some safety measures and Arc Welding (AW) A fusion welding where the coalescence of the metals (base metals and filler) is achieved by the heat from electric arc. Semih Genculu, P.E. Arc welding requires striking a low-voltage, high-current arc between an electrode and the workpiece (base metal). Arc Shielding – To shield the arc from the surrounding gas Electrodes – consumable and non-consumable electrodes. Typical Arc Welding Processes: Shielded metal arc welding (SMAW): Shielded metal arc welding, which is also known as stick welding, is the most widely used process Plasma arc welding (PAW) is an arc welding process utilizing heat generated by a compressed arc between a tungsten non-consumable electrode and workpiece (transferred arc process) or water-cooled constricting nozzle (non-transferred arc process). The joint is produced thanks to the heat exerted through an electric arc that allows the material, with or without filler metal, to melt. The intense heat This site uses cookies.
