Description

Technical Field

[0001] This utility model belongs to the field of electronic and electrical spot welding technology, and in particular relates to an electronic and electrical spot welding device. Background Technology

[0002] Spot welding is a type of resistance welding, which refers to a welding method that uses columnar electrodes to form a weld point between the contact surfaces of two overlapping workpieces. During spot welding, pressure is first applied to bring the workpieces into close contact, and then current is applied. Under the action of resistance heat, the contact area of ​​the workpieces melts, and after cooling, a weld point is formed. During spot welding, the workpieces form an overlapping joint and are pressed tightly between the two electrodes. Its main characteristics are: the heating time of the connection area during spot welding is very short, the welding speed is fast; spot welding only consumes electrical energy and does not require filler materials, fluxes, gases, etc.; the quality of spot welding is mainly guaranteed by the spot welding machine; it is simple to operate, has a high degree of mechanization and automation, and high productivity; it has low labor intensity and good working conditions.
