[0062] S1. The composite welding operator uses the crane to hoist four steel plate materials with cut corners in batches and places them in the welding interval of the laser composite welding machine bed;

[0063] S2. The plate material to be welded into a box-shaped column is placed between the two top plates by the crane, and the hydraulic cylinders on both sides of the plate material are started to drive the two top plates to move relatively and make one side of the plate material inserted into the clamping groove on the side of one of the top plates;
