The utility model relates to a welding equipment technical field, in particular to a laser hybrid welding head device, which comprises a housing, a hybrid welding head, a connection plate, a large gear ring, a sleeve, a pinion and a motor. The hybrid welding head comprises a laser welding torch and an arc welding torch. The motor drives the large gear ring running by the pinion. The sleeve runs simultaneously, which is homocentrically fastened with the large gear ring. The connection plate is fixedly connected with the hollow sleeve. The laser welding torch and the arc welding are positioned on the connection plate, and the laser welding torch is arranged at the central shaft of the sleeve. Therefore, the arc welding torch rotates around the laser welding torch as 360 degree during running. The rotational speed and the rotational angle of the hybrid welding connect can be controlled by the motor running, which can facilitate the hybrid welding head fits the welding on curve weld joint with different curvature or curvature change.
