The invention discloses intelligent weld stress treatment impact equipment. A piezoelectric ceramic pile is connected with an amplitude transformer, the amplitude transformer is connected with a transverse actuator, the transverse actuator is fixedly connected with impact needles, and the transverse actuator is driven by a driving mechanism; furthermore, a camera for collecting weld images is arranged, and a light control lamp is arranged on the near side of the camera; a controller controls the driving mechanism, the camera and the light control lamp to work; two rows of the impact needles for respectively treating weld toes on two sides of a weld are vertically arranged, the two rows of the impact needles move in opposite directions through the transverse actuator and align with the weldtoes on the two sides of the weld. The intelligent weld stress treatment impact equipment disclosed by the invention is reasonable in structure, high in work efficiency and capable of treating the weld toes on the two sides of the weld.
