M.S. Welding Electrode

An electrode is a coated length of wire that are connected with the welding machine to create an electric arc; current passes through the wire and produces an arc, which generates lot of heat to melt and fuse metal for welding. It is made using materials with a similar composition to the metal being welded. These are installed in the weld head to touch and maintain contact with the work pieces through the full weld schedule. Welding is used for joining two or more metals or thermoplastics permanently with help of coalescence. The welding electrodes play three different roles in welding: maintaining uniform current density, concentrating current at welding points, and maintaining thermal balance during welding.
