The invention relates to a process and an apparatus for the cooling of a welding seam area during laser welding of plates or strips, preferably used in car body construction in automotive engineering. It is described how expediently the cooling agent supply and also the supply of an inert gas veil built up between the focus and liquid coolant is achieved so that the liquid coolant is prevented from entering the welding seam area and causing detrimental effects there.
Un procédé et un dispositif servent à refroidir la zone d'une soudure pendant le soudage laser de tôles ou de feuillards métalliques, de préférence lors de la construction de carrosseries dans l'industrie automobile. Il est montré, selon l'invention, comment amener le produit refroidisseur, et créer un voile de gaz inerte entre le foyer et le liquide refroidisseur, cela de sorte que le liquide refroidisseur n'atteigne pas la zone de la soudure et ne l'affecte pas négativement.
