Heat is normally needed to melt the basic metal parts for proper welding. There are three types of welding. The three classes of welding are arc welding, spot welding, and gas welding. Arc welding uses electric current to melt thin sheets of metals. It has been known for a gas torch to be used to melt metal pipes in gas welding method. Spot welding is used in automobile industry to melt metals by robotic process. The work of welding requires one to wear protective items such as the welding mask, gloves, and an apron.
