Electric Welding Machine refers to machines apparatus, and jigs and fixtures required for the fabrication of welded articles from semifinished stock. A welding position, or station, is a set of welding equipment for operations that require some degree of participation by a welder. A welding line combines several welding stations.
Welding stations may be used in arc welding, resistance welding, gas welding, electron-beam welding, or other methods. The welding equipment includes the ARC Stick Welding Machine, power supplies, and devices directly used to conduct the welding process, jigs and fixtures for the rapid assembly of the parts to be welded, for holding the parts during welding, and for preventing or reducing warpage of the welded articles, auxiliary equipment used for transporting the parts during welding and for mounting and transporting the welding apparatus, and various other tools used by the welder. Various transport means and instruments for controlling weld quality are also used in the welding process. The technical characteristics of welding equipment are determined by the welding method chosen, the type of production, and the degree of mechanization, that is, whether manual, semiautomatic, or automatic welding is performed.
A welding station is a section of a production area where a power supply, current-carrying conductors, and necessary jigs, fixtures, and welder’s tools are located. In order to protect personnel in the area from radiation, the welding station is enclosed by curtains or panels. Fixed automated stations are widely used in modern manufacturing processes; such stations are located in manufacturing shops. Mobile stations are used in the field for welding large objects in construction and repair work.
Welding stations include power supplies and equipment for the regulation of the arc during welding. Power supplies used in welding should provide a convenient, continuous or step control and must satisfy general requirements for electric machines and equipment. AC DC TIG Welding Machine, transformers, generators, and rectifiers are used in electric welding; gas generators are used in gas welding. Power supplies may be single-position or multiposition types, stationary installations for continuous, long-term operation, or small, portable units for work of short duration.
