Abstract

Process for the joining of strips and/or sheets of metallic materials, wherein the strips/sheets are introduced converging on one another at an angle into a roll nip, the surfaces coming into contact with one another being heated, but not melted by a laser beam immediately prior to physical contact and the strips/sheets being so pressed together in a directly following joining pass that they are rigidly connected to one another at material surfaces brought into contact.
