A method and apparatus for MIG welding is disclosed. When in an ac mode the output is unbalanced, or the balance may be controlled. The balance may be controlled to provide a desired deposition rate and /or to obtain a desired dilution. The frequency may be any frequency, for example 30 Hz, 60 Hz, 90 Hz, or more. The weld path may have groove with angle of less than 50 degrees.UNIT I GAS AND ARC WELDING PROCESS - RCET2 UNIT I GAS AND ARC WELDING PROCESS Welding is a process of joining two metal pieces as a result of significant diffusion of the atoms of the welded pieces into the joint (weld) region. Welding is carried out by heating the joined pieces to melting point and fusing them together (with or without filler material) or by applyingTypes of Welding Process Everyone Should Know The storage tank holding tank melting tank Submerged arc weldingNov 03, 2017 · In the development of storage tanks. (xi) Stud Arc Welding. It is the most extensively used fastening process. It can weld any type of metal stud to the workpiece. There is a requirement of DC power supply, a welding gun, and metal fasteners. There is no much pressure requirement in this method. Advantages: It is used in jewelry production.
