The system comprises a linear laser distance sensor, a speed sensor, a controller, a sensor protection device, a linear laser distance sensor fixing device, a speed sensor fixing device, a disc support, a semicircular box rotating device, a driving rotating shaft and a driver, wherein a welding gun is perpendicular to a sheet plane, the center of the welding gun is located on the central line of a gap between two sheets, the linear laser distance sensor is connected with the semicircular box rotating device through the sensor fixing device, the welding gun does reciprocating motion once along the gap between the two sheets, and when the welding gun completes a one-way route, the linear laser distance sensor records the height of each point of a lower plate A. Under the control of the driver, the driving rotating shaft rotates and drives the semicircular box device to move together, and the linear laser distance sensor stops when rotating 180 degrees. The line laser distance sensor then records the height of each point of the board B as the welding gun moves. After the weld is complete, the above actions are repeated and the line laser distance sensors again record the post weld height of the welds of the panel A, B, respectively. The system is simple, and can realize the height difference measurement before welding the two sheets and the measurement of the longitudinal height deformation of the sheets after welding.)
