Abstract

A method of laser welding for a steel sheet, in which there can be attained reduction of morphological defects of the weld area of welded material and exhibition of satisfactory bonding strength; and a laser welding apparatus therefor. There is provided a method of laser welding for a steel sheet through causing multiple steel sheets to abut on each other at end faces thereof and irradiating the abutted area of the steel sheets brought into mutual abuttal with laser beams to thereby weld the abutted area, comprising the cutting step of cutting end faces of steel sheets into forms suitable for mutual abuttal; the abutting step of bringing the end faces formed by the cutting step into mutual abuttal; the first heating step of heating the abutted area; and the laser welding step of welding by laser the abutted area having been heated by the first heating step.
