Process for heating a welding material (2) deposited on at least one joining area of at least two components (3, 4) for their welding or separation, in which means (8) emit a heating beam (9) and means (11) emit a detection light beam (12), means (13) cause one of these beams to coincide with the other so that they reach the region to be heated along the same path (14), means (15) deviate this path so that these beams together sweep the region to be heated (5). Before the region to be heated with the heating beam (9) is swept, it is detected by the light beam (12).
