摘要： With many coated plates, in particular zinc (galvanized) and organic coated sheet metal as are employed in the automobile industry, the coating material has a significantly lower boiling point than the melting point of the sheet metal material. Therefore in the case of laser welding of this type of sheet metal with zero gap in the overlap abutment area to a explosion like vaporization of coating material, which take along or entrain molten sheet metal material and strongly damage the quality of the joint. For improving the connection it has already been proposed that no gap be provided between the sheets, but rather these are positioned directly over each other and then first by means of first laser beam to warm until vaporization of the coating and subsequently to weld the uncoated sheets by means of a second laser beam. The disadvantage therein is above all the elaborate apparatus set up or complexity for the two required optical systems. The task of the present invention is thus comprised therein, to reduce the apparatus complexity and at the same time to at least maintain the work quality, preferably to improve it. The task is solved by a process in which by means of a signal laser beam first all plates can be uncoated and thereafter the plates are welded along the uncoated area with the same laser beam.

摘要： During welding with high output power, the gaps between the pieces being joined may not exceed a maximal gap width. A process for laser beam welding is provided, which on the one hand ensures maintaining (not exceeding) a maximal gap width between the sheets and on the other hand makes possible a maximal utilization of the achievable welding speed. The sheets, prior to welding, are first spot welded, wherein they are clamped only during this spot welding in order to ensure the maintenance of a maximum gap width.

摘要： In coated sheets the coating material often has a significantly lower melting point than the material of the sheet. Accordingly, when welding together this type of sheets, there may occur explosion-like evaporation of coating material, which significantly compromises the quality of the joint. For improving the joining quality it has already been proposed to provide a narrow gap between the sheets, through which the vaporized coating material can escape. The present invention provides a process and a device for simple and reliable checking the spacing of the sheets. This is done by a process and a device in which on at least one side of a first sheet topographical changes are produced projecting from the surface, the first sheet is positioned and clamped relative to a second sheet with the topographical changes projecting from the surface defining a minimal spacing between the two sheets through which spacing, during welding, vaporized products can escape, and wherein it is checked whether the two sheets are in contact with each other via the topographical changes projecting from the surface.

摘要： During laser beam welding a so-called end crater forms at the end of the weld seam. The end crater is formed by the volume shrinkage of the solidifying melt after the laser beam reaches the seam end and is switched off or repositioned. The end crater acts as a geometric notch and decreases the mechanical characteristics, in particular the operational stability, of the weld seam so that holes or tears in the area of the end crater can occur. The task of the present invention is thus comprised of providing a process for reducing end crater formation. The task is solved in that towards the seam end the focus of the laser beam is distanced from the surface to be welded and/or a transverse movement of the beam occurs.
