Welding is a method of joining metals using local or general heating, plastic deformation, or the combined effect of both of these processes. As a result of heating, interatomic bonds are restored in the welded parts, which leads to a strong connection. To date, almost a hundred types of welding have been created. The classification of types of welding takes into account technical, technological and physical features. By the way, if you are looking for profiled timber from the manufacturer, then you should follow the link.
According to physical features, thermal, thermomechanical and mechanical welding are distinguished. According to technical features, welding differs in the way of protecting the metal in the welding area, continuity or vice versa, the presence of interruptions during welding, the degree of mechanization, the type of shielding gas used. Each type of welding has its own technological classification features.
Most often in construction and repair work, manual arc welding, automatic and semi-automatic welding of metals using flux, arc welding using shielding gas, electroslag welding, electron beam and plasma welding are used. These basic types of welding also have their own variations.
