Abstract
A device and a method of vibro-spot welding which weld overlapped metal plates by heating welding portions of the overlapped metal plates and applying linear and repetitive load to the welding portions are disclosed. The device of vibro-spot welding may include a pair of vibration welders facing each other with respect to overlapped metal plates, wherein at least one of the pair of vibration welders heats welding portions of the metal plates, generates plastic flow at the welding portions by moving the welding portions reciprocally between the pair of vibration welders, and joining the welding portions by applying pressure to the welding portions at which the plastic flow occurs.
