Beschreibung
Zusammenfassung:	The present invention relates to a laser welding method that is capable of preventing defects such as pores or pits from being formed in a weld and improving formability of the weld during laser welding, and a welded member using the same. In the laser welding method of performing welding by irradiating laser onto a portion to be welded, there are provided a laser welding method of including supplying a shielding gas to a laser irradiation part and a rear side of the laser irradiation part, and a welded member having welds formed therethrough.
