Title: Welding method of thin steel sheets by laser beam
Inventor: MINAMIDA KATSUHIRO
IPC: B23K26/21
Filed: 1984-04-13
Abstract: PURPOSE:To stabilize seam welding and to improve the efficiency thereby by installing a welding wire to a butt part, irradiating a laser beam on the weld line shielded by semispherical cavities under prescribed conditions and maintaining nearly ''1'' effective absorptivity. CONSTITUTION:The welding wire 3 is installed on the weld line of a butt part 2 and the upper and lower parts are shielded by semispherical cavities 4, 4'. The laser beam is first irradiated with low power on the above-described weld line to weld the wire 3, then the normal welding is executed with high power. The energy reflected and radiated from the weld point is converged on the weld point by multiple reflections on the inside surfaces of the cavities 4, 4'. The seam welding is thus stabilized and the efficiency thereof is improved.
