The invention relates to a multi-path high-energy ultrasonic field treatment device for regulating and controlling a welding residual stress. The device sends a control instruction by matching with regulating-controlling system software and via an industrial personal computer; an ultrasonic signal excitation controller receives the control instruction, and then sends a regulating-controlling signal to a high-power ultrasonic amplifier; the high-power ultrasonic amplifier drives a high-energy ultrasonic transducer according to the regulating-controlling signal to generate a high-energy ultrasonic beam; and the energy of the high-energy ultrasonic beam is injected in a residual stress concentrated area in the surrounding of a weld joint according to set requirements, and then is used for regulating the residual stress. The device is simple in structure and good in regulating-controlling effect, can effectively solve the various adverse effects of a residual stress on the dimensional stability, the fatigue stren
