  • the invention has for its object to provide a method and an apparatus for welding all plastically deformable materials at high speeds and while avoiding the aforementioned imperfections.
  • the method according to the invention has the characterizing features of claim 1.
  • the melt is squeezed by the deformation in such a way that it fills the entire gap and, moreover, the melt is also pressed out of the gap.
  • the sweatband is not squeezed or deformed exclusively in the liquid phase, but also during the transition to the solid phase when the material has already reached a pasty state.
  • OMPI IPO This effectively counteracts the formation of voids in the weld seam. Likewise, pore formation in the weld seam is prevented by the deformation or crushing.
  • the deformation is not limited to the melt, but also the edge areas of the sheet metal or sheets adjacent to the abutting surfaces are deformed. These areas are deformed plastically, that is to say permanently, the deformation preferably taking place in a direction running transversely to the plane of the gap between the abutting surfaces.
  • the direction of deformation can also run obliquely to the plane of the gap with different degrees of deformation over the thickness of the metal sheets. Since a mostly permanent deformation is carried out in and around the weld seam, the shrinkage stresses occurring when the melt cools rapidly and the areas of the abutting surfaces adjoining it are largely compensated for or reduced.
  • the sheets can be deformed by 10% of their thickness. The deformation thus exceeds the extent of the shrinkage of the sheets as a result of the latter cooling from welding to nominal temperature.
  • the metal sheets or the metal sheet are continuously moved past the focused laser beam with the weld joint. This creates a continuous, continuous weld.
  • welding speeds of more than 80 m / min can be achieved with the welding method according to the invention.

  • a powder of the same material can be applied to the joint surfaces to be welded in a lacquer-like manner. This serves to increase the absorption of the laser on the abutting surfaces, the grain size for the powdery additive preferably being above 10 ⁇ m (micrometers).
  • other additives for the targeted alloying of the melt of the sheets to be welded can be used, for example Ni powder or Ni foil for welding iron materials. Alloying the melt with such an additive prevents embrittlement of the material when heated to the melting point and then cooled. Other additives are conceivable to improve the welding properties of the sheet or sheet.
  • the welding method of the invention can be carried out in a wide variety of gases. This enables inert gas welding to be carried out in order to avoid scaling of the metal sheets at the heated edge areas of the abutting surfaces and to prevent diffusion of pollutants from the atmospheric air into the melt.

  • a compression of the weld seam is thus to be carried out step by step in order to limit the degree of deformation in the sheets and the weld seam and to reduce the load on the pressure elements.

Abstract

La vitesse de soudage de matériaux plastiquement déformables lors de l'utilisation de sources d'énergie de puissance volumique importante, par exemple d'un rayon laser focalisé (44), est limitée par la formation de défauts (criques, retassures, soufflures et piqûres, etc.) dans la soudure ou près de celle-ci (soudure bord à bord 11). Afin d'augmenter la vitesse de soudage tout en évitant ces défauts, la présente invention propose de déformer la soudure (soudure bord à bord 11) et les régions voisines des tôles (14, resp. 15) de façon à serrer la masse fondue formée pour le soudage et provenant du joint de soudure, à éviter retassures ainsi que soufflures et piqûres et à prévenir des contraintes de soudage par déformation plastique dans la région de la soudure bord à bord (11). Simultanément à la déformation de la soudure bord à bord (11), il est possible de procéder à son lissage.
