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.
