During this period, the first clamping shaft 16 and the second clamping shaft 17 begin to expand. The expanded diameters of the first clamping shaft 16 and the second clamping shaft 17 are designed to fit the sides of the honeycomb regular polygon, so that the first clamping shaft 16 and the second clamping shaft 17 are While clamping the wavy strip, alignment correction is achieved and it is positioned at the welding position. The rear end positioning or the wavy strip after welding can always be fixed by an external conventional fixing mechanism (to facilitate precise fitting with the wavy strip positioned in front by the first clamping shaft 16 and the second clamping shaft 17). Then the first slide 3 on the first rodless cylinder guide rail 2 is controlled to move so that the laser welding head 6 welds the fitting part.
