A welding power supply is a device that provides or modulates an electric current to perform arc welding. [1] There are multiple arc welding processes ranging from Shielded Metal Arc Welding (SMAW) to inert shielding gas like Gas metal arc welding (GMAW) or Gas tungsten arc welding (GTAW).
The Hobart Corporation is an American mid-market provider of commercial grocery and foodservice equipment. The company manufactures food preparation machines for cutting, slicing and mixing , cooking equipment, refrigeration units, warewashing and waste disposal systems , and weighing , wrapping, and labeling systems and products.
The company was founded in 1895 by John C. Lincoln with an investment of $200 to make electric motors he had designed. [3]The company is headquartered in Euclid, Ohio, and has 44 manufacturing locations, including operations and joint ventures in 19 countries and an international network of distributors and sales offices covering more than 160 countries.
Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.
Spot welding (or resistance spot welding [1]) is a type of electric resistance welding used to weld various sheet metal products, through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current.
Orbital welding is a specialized area of welding whereby the arc is rotated mechanically through 360° (180 degrees in double up welding) around a static workpiece, an object such as a pipe, in a continuous process.
Plasma arc welding is an arc welding process wherein coalescence is produced by the heat obtained from a constricted arc setup between a tungsten/alloy tungsten electrode and the water-cooled (constricting) nozzle (non-transferred arc) or between a tungsten/alloy tungsten electrode and the job (transferred arc). The process employs two inert ...
For welding thin-walled parts, appropriate welding aids are generally needed. Their construction must provide perfect contact of the parts and prevent movement during welding. Usually they have to be designed individually for a given workpiece. Not all materials can be welded by an electron beam in a vacuum.
