  • Method for monitoring collision welding of a component
    Patent number: 11471983
    Abstract: The present invention relates to a method and a device for monitoring the process for a welding seam formed by means of collision welding, in which a first joining partner (1) and a second joining partner (2) are moved toward one another by an introduction of energy and are welded to one another to form the welding seam. A light flash between the first joining partner (1) and the second joining partner (2) is detected during the welding by an optical capture unit (6), which measures in a time-resolved manner, having at least one detector (19, 20, 24) and an actual value of a beginning of the light flash, a duration of the light flash, an intensity of the light flash, and/or an intensity distribution over time of the light flash is determined by an analysis unit (16) and compared to a respective target value of the beginning of the light flash, the duration of the light flash, the intensity of the light flash, and/or the intensity distribution over time of the light flash.
