Mechanical bonding refers to local plastic deformation on the joint surface, such as bolting, riveting, and heat-fitting. Metallurgical bonding is the method of locally fusing by applying thermal energy to the bonding surface or promoting the thermal diffusion of metal atoms, most of which belongs to this method. The components required for the welding work include welding of the base material (material), heat source (gas heat or electric energy mainly used as a heating source, heat of chemical reaction, mechanical energy, electromagnetic wave energy) Welders and welding equipment (welding cables, holders, tundishes, and other tools) are required.

On the other hand, the welding method is divided into welding, pressure welding and soldering according to the heating temperature and the heating method, and ARC welding, gas welding and special welding are used for the welding of welding. The ARC welding is divided into consumable electrode type and non- . Gas welding is classified into oxygen-acetylene, oxygen-hydrogen, and air-acetylene welding. Special welding is divided into thermite welding, electronic beam welding, electroslag welding, and plasma welding.
