In one embodiment of the present application, the adjustment mechanism 30 includes a driving structure 31 and a robot arm 32, one end of the robot arm 32 is connected to the laser welding head 20, and the other end is connected to the driving structure 31; the driving structure 31 is used for driving the mechanical arm 32 to move to adjust the position of the laser welding head 20 under the control of the control communication device 40, so that the laser welding head 20 is directly opposite to one of the areas to be welded of the shear wall 200 of the corrugated steel plate to be welded, and the vertical distance between the laser welding head 20 and the area to be welded is smaller than a first threshold value.
In the embodiment of the present application, the driving structure 31 of the adjusting mechanism 30 is in communication connection with the control communication device 40, and is configured to receive a control signal of the control communication device 40, so as to drive the mechanical arm 32 to move, and through the movement of the mechanical arm 32, the laser welding head 20 is driven to move, so that after the laser welding head 20 moves to a target position, the control communication device 40 controls the laser generating device 10 to generate laser, and the laser welding head 20 emits the converged laser beam, so as to perform welding work on the shear wall 200 of the corrugated steel plate to be welded.
