The invention belongs to the technical field of laser welding methods, and particularly relates to ultrasonic-assisted laser-CMT composite welding equipment and method. The laser welding system comprises a laser device and a laser welding gun, and the laser device is electrically connected with the laser welding gun; the CMT welding system comprises an electric arc welder and a CMT welding gun, and the electric arc welder is electrically connected with the CMT welding gun; the laser welding gun is vertically placed above a welded workpiece, the CMT welding gun is obliquely arranged above the welded workpiece, the end of a gun head of the CMT welding gun is rigidly fixed to the end of a gun head of the laser welding gun, and the ultrasonic generator is connected with the ultrasonic vibration head through a wire. According to the method, ultrasonic vibration is applied on the basis of laser-CMT welding, so that the forming and mechanical properties of a welding seam are improved; according to the ultrasonic-ass
