| 摘要 |
The subject of the present invention is a method of butt welding metal sheets (1, 2) by means of a laser beam, characterised in that a lateral compressive force F is exerted on the metal sheets (1, 2) to be welded, this force being directed towards the junction plane (3) of the metal sheets (1, 2) so that the contact pressure between the said metal sheets, at any point in the junction plane (3), is between 0.05 times the yield stress (elastic limit) of the metal sheet (1 or 2) having the lower yield stress and the buckling stress of the metal sheet (1 or 2) having the minimum buckling stress, and a welded joint is produced at the junction plane (3) by locally melting the said metal sheets (1, 2) by means of the laser beam. The subject of the invention is also a welding arrangement (device) for the implementation of this method. <IMAGE> |
