Abstract
A method for joining materials by laser radiation is provided. The laser radiation is focused onto a focal area, which is small compared to a working area, and a specifiable intensity distribution is achieved over the working area by moving the focal area across the working area. Also provided is a device for joining materials by laser radiation, a focal area of the laser radiation, which is small compared to a working area, being movable across the working area with the aid of movable optical components, and a disk laser or a fiber laser being provided as the source of radiation. The method and the device may make it possible to set almost any intensity distribution over a working area, thus to achieve a reproducible welding process adapted to the joining task.
