During the welding process, the workpiece and the solder melt to form a melting zone, and the molten pool is cooled and solidified to form a connection between the materials. This process, usually also need to exert pressure. There are many sources of welding energy sources, including gas flame, arc, laser, electron beam, friction and ultrasound. Before the end of the 19th century, the only welding process was followed by hundreds of years of blacksmithing by blacksmiths. The earliest modern welding technology appeared in the late 19th century, first arc welding and oxygen gas welding, followed by resistance welding. In the early 20th century, with the first and second world wars waged, there was a great demand for cheap and reliable connections to military equipment, thus promoting the development of welding technology. Today, with the widespread use of welding robots in industrial applications, researchers are still delving into the nature of welding and continue to develop new welding methods to further improve the welding quality.
