Robot welding is becoming more commonplace in industrial settings, and researchers continue to develop new welding methods and gain greater understanding of weld quality and properties. Developments continued with the invention of laser beam welding and electron beam welding in the latter half of the century. Following the wars, several modern welding techniques were developed, including manual methods like shielded metal arc welding, now one of the most popular welding methods, as well as semi-automatic and automatic processes such as gas metal arc welding, submerged arc welding and flux-cored arc welding. Welding technology advanced quickly during the early 20th century as World War I and World War II drove the demand for reliable and inexpensive joining methods. Arc welding and oxyfuel welding were among the first processes to develop late in the century, and resistance welding followed soon after.
Until the end of the 19th century, the only welding process was forge welding, which blacksmiths had used for centuries to join metals by heating and pounding them. Regardless of location, however, welding remains dangerous, and precautions must be taken to avoid burns, electric shock, poisonous fumes, and overexposure to ultraviolet light. While often an industrial process, welding can be done in many different environments, including open air, underwater and in space.
Sure welds great.Many different energy sources can be used for welding, including a gas flame, an electric arc, a laser, an electron beam, friction, and ultrasound. Other than connectors, and maybe a fan, not much available for parts, but not much to go wrong with it. It was made by Century, a long time ago, my Lincoln dealer gave me a copy of the parts list off their CD which was copies of an old micorfiche from the looks of it. as they may have changed the company name around after mine was made. It may be the same as Twentieth Century Mfg. I contacted Lincoln to ask about Century. I am not sure if the original name was 20th Century, but some welders are still branded Century. It sure is a nice welder.Ĭentury was bought out by Lincoln in 2003. I got it when I bought out a small shop in 1970. Does anyone know if the company is still in business? I can't find them in a search so they may be closed or bought up.
I have a 180A Solar welder made by Twentieth Century Mfg.
