Abstract: The invention relates to a method for laser welding the end faces of the joints (5, 6) of two connecting flanges (3, 4), which are held in an adjoining manner, of two connecting partners (1, 2) made of a steel material. According to the method, in addition to being moved in the advancement direction, which follows the longitudinal extension of the joints (5, 6), the welding laser beam (8) is moved back and forth in an oscillating manner transversely to the advancement direction. At least one of the two connecting partners (1, 2) to be welded at the connecting flange (3, 4) joints (5, 6) is equipped with a metal coating at least in the region of the respective connecting flange (3, 4). The weld pool produced by the energy input during the laser welding process is kept in a liquid state in order to allow degassing processes and/or distribution processes to be carried out in a controlled manner for phases of the metal coating of the at least one connecting partner, said metal coating being integrated by the welding process, wherein the welding laser beam is oscillated at a frequency of at least 80 Hz.

Abstract: A method of joining at least two substrates includes welding the at least two substrates together with a multi-step welding process. The multi-step welding process includes: reducing a mismatch between the at least two substrates by melting on both sides of the at least two substrates to form a melted portion that does not overlap a joint line between the at least two substrates with a first welding step; and increasing melt volume and penetration depth of the melted portion between the at least two substrates with a second welding step.

Abstract: A welding method materially cohesively bonding at least two components using at least one additive material. A welding seam is produced with a seam course between a seam start and a seam end. The process is controlled using at least one control unit, at least one external physical welding seam property of the welding seam is influenced by a control parameter of the control unit, and information is included in the control parameter. The information, during the process is stored in the welding seam between a start point and an end point in the seam course using the at least one external physical welding seam property so that the information can be read, optically and/or haptically, from a sequence of the at least one detectable external physical welding seam property along the course of the seam in the region between the start point and the end point.

Abstract: Methods for joining a first blank and a second blank, at least one of the first and second blanks comprising at least a layer of aluminum or of an aluminum alloy or a layer of zinc or of a zinc alloy. The method comprises selecting a first portion of the first blank to be joined to the second blank, and selecting a second portion of the second blank to be joined to the first portion, and welding the first portion to the second portion. The welding comprises using a filler metal laser beam and a welding laser beam, and displacing both laser beams in a welding direction to melt and mix a filler wire material with the melted portions of the two blanks. The present disclosure further relates to blanks obtained by any of these methods and to products obtained from such blanks.

Abstract: A laser welding device that laser-welds a lid to an open portion of a casing emits a laser beam to a joining subject portion including an inner side surface of the casing that defines the open portion and a peripheral surface of the lid that faces the inner side surface of the casing. The inner side surface of the casing and the peripheral surface of the lid are arranged to form a groove in between, and include inclined surfaces that function as a sliding portion. The groove portion has a groove width that is variable by sliding the sliding portion. A detection unit detects the groove width of the groove portion. An adjustment force application unit applies force for adjusting the groove width to the casing. A control unit controls the force applied by the adjustment force application unit in accordance with the groove width detected by the detection unit.
