Zusammenfassung:	Method for manufacturing a spark plug (1) for a combustion engine, wherein the spark plug (1) has at least two components which are joined by at least one welded joint which has been manufactured in a welding process, wherein for improving selected material properties of the welded joint a laser beam (8) is directed to the welded joint and in that a powder (5) which improves the selected material properties is introduced into the welded joint which is melted on its surface by the laser beam (8) such that the powder (5) melts and due to a connection of the melted powder (5) with the melted aggregate structure of the surface of the welded joint a treated area with improved material properties results. L'invention concerne un procédé de fabrication d'une bougie d'allumage (1) destinée à un moteur à combustion interne, la bougie d'allumage (1) présentant au moins deux éléments qui sont reliés entre eux par l'intermédiaire d'au moins une liaison par soudage fabriquée dans un processus de soudage, un faisceau laser étant dirigé sur la liaison par soudage pour améliorer des propriétés de matériau choisies de la liaison par soudage, et une poudre améliorant les propriétés de matériau choisies étant introduite dans la liaison par soudage fondue à sa surface par le faisceau laser, de façon à faire fondre la poudre (5) et à former une zone traitée dotée de propriétés de matériau améliorées, par liaison de la poudre fondue (5) avec la structure mélangée fondue de la surface de la liaison par soudage.
