Abstract

Se describe un método para soldar por ojo de cerradura con láser una pila de hojas de metal a una lengüeta de metal; el método ajusta de manera independiente la potencia en un rayo central enfocado y la potencia en un rayo anular enfocado para formar una soldadura a través de todas las hojas y la lengüeta; el rayo anular proporciona la potencia suficiente para calentar el metal hasta aproximadamente la temperatura de fusión, ensanchar una boca de un ojo de cerradura, y estabilizar un baño de fusión; el rayo central proporciona una potencia adicional suficiente para formar el ojo de cerradura; la potencia del rayo anular es sostenida durante un tiempo más largo que la potencia del rayo central; se forma una pluralidad de dichas soldaduras para proporcionar resistencia mecánica y conductividad eléctrica.
