Title (EN) MODIFYING THE POWER DURING WOBBLING
(FR) MODIFICATION DE LA PUISSANCE LORS D'UNE MODULATION
(DE) VERÄNDERUNG DER LEISTUNG BEIM WOBBELN
Abstract:
(EN) During the wobbling process, the laser power (P) is lowered for a short period of time in the region of the cusps (16', 16",...), thus allowing for better welding results.
(FR) L'invention concerne une modification de la puissance lors d'une modulation. Lors de la modulation, la puissance laser (P) est temporairement diminuée dans la zone du point d'inversion (16`, 16``,...), ce qui permet d'obtenir de meilleurs résultats de soudage.
(DE) Beim Wobbeln wird die Laserleistung (P) kurzzeitig im Bereich des Kehrpunkts (16`, 16``,...) erniedrigt, so dass sich bessere Schweißergebnisse erzielen lassen.
