Double-metal material friction gas welding valve detection device

The utility model relates to a double-metal material friction gas welding valve detection device, which comprises an L-shaped base. Two sides of the base are respectively provided with a rotation device and a top pressure device, and the rotation device and the top pressure device are mutually vertical. A hydraulic device is arranged at the groove of the L-shaped base. The hydraulic device is connected with the top pressure device via a hydraulic oil pipe. A safety protection device is arranged outside the rotation device. according to the double-metal material friction gas welding valve detection device, the operation is convenient, the performance is stable, the double-metal material friction gas welding valve welding seam strength can be 100% detected, and simple, convenient, quick and reliable nondestructive detection can be carried out on the welding seam of the friction weld; time and labor are saved, manual work is saved, nondestructive detection can be realized, the device can be continuously used, co
