Abstract

Problema: Detectar fácilmente un defecto de agujero que ocurre después de la soldadura. Solución: Un dispositivo 10 de soldadura por láser comprende una unidad 30 de irradiación de láser que irradia haz 31 de láser, un detector 41 de luz visible que detecta la intensidad V1 de emisión de la luz 40 visible que se emite desde una porción 21 soldada que se suelda utilizando el haz de láser que se irradia desde una unidad de irradiación de láser, y una unidad 70 de control. La unidad de control puede libremente conmutar la operación de la unidad de irradiación de láser entre un modo de soldadura para soldar una pluralidad de miembros 20 metálicos entre sí irradiando haz de láser y un modo de inspección para irradiar el haz de láser nuevamente sobre la porción 21 soldada como una luz 32 de inspección. La unidad de control conmuta la operación de la unidad de irradiación de láser al modo de inspección después del modo de soldadura e irradia el haz de láser nuevamente desde la unidad de irradiación de láser sobre la porción soldada como una luz de inspección. La unidad de control adicionalmente detecta un agujero que se genera después de la soldadura con base en los cambios en la intensidad de emisión de la luz visible que se emite desde la porción soldada debido a la irradiación de la luz de inspección, con base en una señal de detección procedente del detector de luz visible.
