Abstract

L'invention concerne un procédé de soudage d'un empilement au moins partiel d'au moins deux tôles pour leur assemblage l'une à l'autre, au moins une excroissance (2) métallique étant intercalée entre lesdites au moins deux tôles. Ladite au moins une excroissance (2) métallique est réalisée sous forme d'un dépôt de matière par soudage préalable direct et local sur une (1) des tôles, lesdites au moins deux tôles étant empilées au moins partiellement avec ladite au moins une excroissance (2) métallique sur une (1) des tôles pointant vers l'autre tôle en vis-à-vis lors d'un empilement au moins partiel desdites au moins deux tôles avant soudage par résistance, les dimensions de ladite au moins une excroissance (2) métallique étant suffisantes pour effectuer une concentration de courant lors du soudage par résistance entraînant une fusion de ladite au moins une excroissance (2) métallique.The invention relates to a method of welding an at least partial stack of at least two sheets for their assembly to one another, at least one metallic protuberance (2) being interposed between said at least two sheets. Said at least one metallic protuberance (2) is produced in the form of a deposit of material by direct and local preliminary welding on one (1) of the sheets, said at least two sheets being stacked at least partially with said at least one protuberance ( 2) metallic on one (1) of the sheets pointing towards the other facing sheet during at least partial stacking of said at least two sheets before resistance welding, the dimensions of said at least one protuberance (2) ) metallic being sufficient to effect a concentration of current during resistance welding resulting in melting of said at least one metallic protuberance (2).
