Laser ablation and welding method for workpieces

A laser ablation and welding method for workpieces, comprising:

• a) inserting at least two workpieces into a clamping unit;
• b) clamping the workpieces in the clamping unit via a first clamping mechanism each in a first position;
• c) aligning the clamped workpieces and the first clamping mechanism, which clamps the workpieces, in a first ablation position;
• d) ablating at least one joining edge of at least one clamped workpiece using at least one laser head;
• e) clamping a first of the at least two workpieces via a second clamping mechanism in the first position and disengaging the first clamping mechanism at the first of the at least two workpieces;
• f) moving the first clamping mechanism in a direction of a joining edge of the first workpiece;
• g) clamping the first workpiece via the first clamping mechanism, disengaging the second clamping mechanism, and aligning the first workpiece and the first clamping mechanism in a joining position;
• h) clamping a second of the at least two workpieces via the second clamping mechanism in the first position and disengaging the first clamping mechanism at the second of the at least two workpieces;
• i) moving the first clamping mechanism in a direction of a joining edge of the second workpiece;
• j) clamping the second workpiece via the first clamping mechanism, disengaging the second clamping mechanism, and aligning the second workpiece and the first clamping mechanism in the joining position;
• k) connecting via welding the workpieces at the respective joining edge;
• and
• l) disengaging the first clamping mechanism and transferring the joined workpieces to a transport unit.
