Title: WELDING METHOD AND WELDING DEVICE
Abstract:
A welding device (100) for projecting laser light on a welding section (3) of objects to be welded (1, 2) that extends as a band and welding same. The welding device is provided with: a first laser-projecting means (104) disposed along the direction that the welding section (3) extends; a transparent jig (102) for ensuring close contact in the welding section (3) of the objects being welded (1, 2); and light-shaping sections (110) for shaping the laser light beam from the first laser-projecting means (104). The light-shaping sections (110) are configured from lenses that expand the shape of the laser light beam in the direction (L-direction) in which the welding section (3) extends and match the shape of the laser light beam to the width in the width direction (W-direction).
