METHOD FOR LASER-WELDING FOR TAILOR WELDED BLANKS AND WELDED METAL USING THE SAME

摘要

The present invention relates to a welding method for tailor welded blanks of a vehicle and a laser welding material manufactured by the same. For the same, in the laser welding method welding a portion to be welded by radiating lasers to the portion, the present invention provides the laser welding method characterized by using solid lasers of which wavelength patterns are less than or equal to 1.2 m when radiating the lasers and the welding material with a welded unit manufactured by the same.
