Description

Technical Field

[0002] Resistance welding refers to a method of locally heating the weldment by using the resistance heat generated by the current passing through the weldment and the contact point as a heat source, and applying pressure for welding at the same time. During welding, no filler metal is required, the productivity is high, the weldment deformation is small, and it is easy to realize automation. Resistance welding uses the resistance heat effect generated by the current flowing through the contact surface of the workpiece and the adjacent area to heat it to a molten or plastic state to form a metal bond. Workers need to clamp and fix the metal plates when welding them, but the existing clamping devices are inconvenient to clamp and fix metal plates of different specifications and models, and the position of the metal plates cannot be adjusted, so the practicality is low.
