Welding is the process of heating and melting metal parts to join them together permanently. Welding is also used to join beams when constructing bridges and buildings. Some welders work at steel mills, railroad shops, and highway departments. Other welders are cutters, using their tools to cut metal into pieces, as required by a blueprint or design, or to cut structures into pieces so they can be discarded. There are more than a hundred methods of welding, which use electricity or various gasses to create the high temperatures that bond metals. Arc welding, which can be done either by hand or by machine, is the most common form. Another common form of welding uses gas. Many types of gas can be used, but a common example is an acetylene and oxygen torch.
