摘要： In many cases, the coating material of coated sheet metal has a significantly lower boiling point than the sheet metal material. Thus, an explosive vaporization of coating material can occur when sheet metal of this type is joined by welding, negatively affecting the quality of the connection. To improve the connection quality, narrow gaps are created by means of spacers, allowing the vaporized coating material to escape through said gaps. The spacers are created e.g. by the laser radiation of the sheet metal. The aim of the invention is to reduce the variations in distance between the sheet metal sheets by the appropriate shaping of the spacers. This is achieved by a method, in which the laser beam executes a movement comprising transverse and longitudinal components through and/or around the center of its processing surface. This creates a topographical modification with a spherical form, i.e. with an apex radius that is greater than the height of said topographical modification.

摘要： The application of anti-corrosion base coating by cataphoretic painting (KTL) is well known in manufacturing automobile body parts. However, the cataphoretic paint can penetrate only incompletely or possibly not at all into the gap in the contact areas of the components joined to each other. This type of gap is conventionally sealed following cataphoretic painting, in order to ensure corrosion protection for the entire assembly. The present invention makes it possible to dispense with the sealing in the production of an assembly of joined conductive components and nevertheless to ensure a sufficient corrosion protection. By introducing topographic changes in the components projecting from their surface in the known contact areas and then joining these components, they are spaced apart by the projecting topographic changes in such a manner that during cataphoretic painting the paint wets the entire surface of the assembly.

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 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.

摘要： For increasing the load bearing capacity of spot-like weld seams for producing a durable joint between at least two components, it is known to lengthen this linearly, that is, to weld with a longitudinal orientation extending more than 30 mm. Such linear weld seams, however, do not endure high loads. The task of the present invention comprises providing linear weld seams with increased load bearing capacity and a process for their production. This task is solved by a process specifically for increasing the load bearing capacity of a linear weld seam for producing a durable joint between at least two components, wherein the location with the highest probability of a weld seam break is determined and then, at this location, a discontinuity is introduced into the weld seam, in such a manner that the tangent of the connecting line exhibits an angle of 15° or more.
