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.
A welding transformer is used to match the parameters of the welding circuit and the power supply; it also functions as a voltage regulator. In Stud Welding Machine, the voltage is regulated mechanically or electrically. In the former case, the distance between the primary and secondary windings is altered. Electrical regulation is accomplished by changing the control currents in supplementary windings, located on the upper and middle field frames of the transformer. In this method, the secondary winding is divided into two sections, one of which is located in the upper window of the transformer. Such a transformer is capable of producing various no-load voltages without a change in the turn ratio; this property is required for welding adjustments. Welding transformers used in resistance welding have a minimum short-circuit resistance and a secondary winding that usually consists of one or two turns. Changes in secondary voltage are achieved by tapping sections of the turns of the primary winding.
Air Plasma Cutting Machines are becoming an increasingly common tool in many industries such as metal fabrication, construction and automotive repair. This tool is able to cut through several types of metal including steel, copper, brass and aluminium by generating an extremely high-temperature, electrical channel of ionised gas otherwise known as plasma.
To create the 4th matter – the plasma – the cutter sends an electric arc through a gas, (either oxygen, nitrogen or argon) which rapidly increases the heat levels to the point where it goes beyond a solid, liquid or gas and becomes plasma. The machine will then use the plasma to transfer the energy to any conductive metal, allowing it to cut through with very little or no resistance. This method results in a clean, fast cutting process.
Laser Welding Machine or laser beam welding is one of the most widely known, accurate types of welding processes. It is a non-contact, high power density welding process used to join multiple pieces of material together using energy emanating from a laser beam. Aerospace, defense and military, medical, electronics, petrochemical refining, communications and energy are some of the common areas where laser welding techniques are applied extensively.
Deep weld penetration and minimized heat inputs are the special characteristics that set laser welded products apart from other conventional welding processes;
Pulsed or continuous laser beams are used depending upon the welding application;
There are many types of laser welding available and the most popular types include Nd:YAG laser welding, CO2 laser welding, and diode pumped laser welding;
Deep narrow welds, without any distortion, and minimal heat-affected zones can be obtained using our laser welding machines that can function at increased travel speeds.
