Quality detector for welding position of steel structure

The utility model relates to the technical field of welding strength detection, and discloses a steel structure welding position quality detector which comprises a base and vertical plates, the vertical plates are vertically welded and fixed at the front end and the rear end of the two sides of the base, the vertical plates are parallel to each other, and a transverse rod for detection is transversely fixed between the vertical plates at the front end and the rear end above the base. And the tail end of the transverse rod is embedded into the vertical plate, inner cavities are formed in the two sides of the interior of the transverse rod, a vibration motor is embedded into the interior of the transverse rod, and an electric push rod for providing a pushing effect is installed on the surface of the lower portion of the middle of the base. According to the technical scheme, the vertical plates are used for fixing the two transverse rods to be located on the two sides of the upper portion of the base, the electr
