Classification of welding
Metal welding, according to the characteristics of its process, divided into welding, pressure welding and brazing three categories.
Welding is a method in which the workpiece interface is heated to a molten state during welding, and welding is completed without applying pressure. During welding, the heat source rapidly heats and melts the interfaces of the two workpieces to be welded to form a molten pool. The molten pool moves forward along with the heat source, forming a continuous weld seam after cooling and connecting the two parts together.
