A welder is a person who wields the metals and then combines them. This process includes heating of metal. Basically, the welder has to join different metals together to make a final product which can be used for different purposes by the firm. A welder uses mainly these processes to complete this task of welding, i.e. shielded metal arc welding, resistance welding, plastic welding and gas metal arc welding. With the advancement in the technology, there are also some other techniques of welding which a welder should know such as laser beam welding, electron beam welding, Gas tungsten arc welding (GTAW), laser hybrid welding, x-ray welding etc. Most welders have to work inside a factory but sometimes they may also have to work outside at the project site. Welders are one of the important assets of any company. Welders have even played a huge part in world wars for their respective armies and countries.
