<p>The present invention relates to a laser beam welding structure for welding workpieces(1,2) by emitting laser beam(4) onto a work portion(6) of the workpieces (1,2), the size of the workpiece and resin member can be minimized and, when welding workpieces(1,2) by emitting laser beam(4) onto the work portion(6) of the workpieces(1,2), burning of the resin member covering the workpiece and located near the work portion(6), due to the reflected laser beam(3) caused from surface of a melting portion(6A) of the workpiece on the working portion(6) can be prevented. In a laser beam welding structure for welding two workpieces(1,2) by emitting laser beam(4) onto the work portion(6) between the two workpieces(1,2), wherein resin members covering the workpieces(1,2) are provided at the position receiving the reflected laser beam(3) from surface of a melting portion(6A) on the working portion (6) when emitting laser beam(4) onto the work portion(6), resin members(5a,5b) capable of transmission of the reflected laser beam are employed for the resin member(5) located at the position receiving the reflected laser beam(3) so as to absorb the reflected laser beam (3) from surface of the melting portion (6A) when emitting laser beam(4) onto the work portion (6) between the two workpieces(1,2) and to prevent burning of the resin member(5).</p> |
