PURPOSE: To obtain a superior welding quality and to exert a lateral contact pressure to sheet blanks suitable for the parameter of sheet blanks to be welded and for the treatment of the edges to be welded of the sheet blanks. CONSTITUTION: Provided are a means 10 for supporting and positioning a first sheet blank 2 in a reference plane, a means 20 for positioning the edge to be welded of the first sheet blank 2 on the axis of the laser beam, and a means 30 for maintaining a second sheet blank on the axis of the laser beam. In addition, a mans 40 for clamping the first sheet blank 2, a means 50 for supporting and positioning the second sheet blank 3 in the reference plane, a means 60 for maintaining the second sheet blank 3 against the edge to be welded of the first sheet blank 2, a means 70 for claming with a sectorized pressure the second sheet blank 3, and a means 80 for exerting a lateral and sectorized pressure on the edges to be welded of the sheet blanks 2, 3 are provided. The sheet blanks are welded using a laser beam movable along the joint plane of the sheet blanks 2, 3 to be welded. |
