s6, driving the first workpiece (210) and the second workpiece (220) to synchronously rotate through two clamping assemblies (230), and performing laser welding at a welding point by using laser welding equipment (600);
s7, in the rotating process of the first workpiece (210) and the second workpiece (220), the positions of the welding positions change due to the track change of the welding points, and at the moment, the telescopic mechanism (500) and the rotating mechanism (400) are matched with each other to drive the positions of the working ends of the laser welding equipment (600) to be synchronously adjusted;
and S8, after welding of the first workpiece (210) and the second workpiece (220) is finished, loosening working ends of the two clamping assemblies (230), and taking down the two welded workpieces.
