摘要： A frame structure of a battery housing for a vehicle driven by an electric motor. The frame structure is composed of individual profiled hollow-chamber sections which are designed to be at least two-chambered in the z-direction and are welded together to enclose a battery volume. The end faces of two profiled hollow-chamber sections are designed to be stepped, such that an end face portion of each of the two profiled hollow-chamber sections borders a lateral surface portion of the respective other profiled hollow-chamber section.

摘要： A description is given of a method for the laser welding of two parts to be joined (1) that are positioned in relation to one another, in which method the laser head, with the laser beam (9) emitted from it, and the two parts to be joined (1), with the joint (3) thereof, are moved in relation to one another in a feeding direction along the longitudinal extent of the joint (3) and the laser beam (9) produces in the joint (3) a weld seam with a target welding-in depth (8) which is deeper than the critical welding-in depth of the parts to be joined (1), wherein the welding method is performed in two steps and, to form the weld seam connecting the two parts to be joined (1), in a first step material in the joint (3) is melted by the laser beam (9) down to the target welding-in depth (8) and wherein, in a subsequent step, the weld seam produced by the first step is melted once again down to a welding-in depth which, as a maximum, corresponds to the critical welding-in depth of the parts to be joined (1). A description is also given of a welded construction (11) produced by this method.

摘要： A bumper cross member for a motor vehicle, having a crossmember extending transversely to the longitudinal axis of the vehicle, and two crashboxes connected thereto and designed as hollow chamber sections. Each crashbox is connected with its end facing away from the vehicle to the crossmember in a respective end section thereof, and may be connected, with its end facing the vehicle, to a structural component of the vehicle. The crashboxes are supported with their end faces only in sections on the rear side of the crossmember, in particular such that the support is continuous or at least substantially continuous either in the upper and lower end-face areas, or in the two lateral end-face areas, while support of the other end-face areas is provided only in sections or absent. The distance between the end-face areas of the crashboxes, which are unsupported on the crossmember, is set from the rear side of the crossmember, such that only after a first phase of energy absorption with deformation of the crashbox is the end face facing the crossmember supported over its whole surface on the rear side of the crossmember.

摘要： 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.
