RESIN MEMBER WELDING METHOD

摘要

A method for welding laser-impermeable resin members. The resin members are overlapped with each other at least partially, with a light absorber capable of absorbing laser light being interposed therebetween, so as to form an overlapping portion. The light absorber in the overlapping portion is irradiated directly with laser light, and is heated and melted thereby. Heat from the melted light absorber is transferred to the resin members in the overlapping portion, and therefore the resin members are melted in the overlapping portion. The melted overlapping portion is cooled and solidified, whereby the overlapping portion is integrally bonded.

1. A method for welding two laser-impermeable resin members, comprising the steps of:
overlapping the resin members with each other at least partially, with a light absorber being interposed therebetween, so as to form an overlapping portion; and irradiating the light absorber directly with laser light, wherein, in the irradiating step, the light absorber absorbs the laser light and is heated and melted, heat from the melted light absorber is transferred to the resin members in the overlapping portion, and the resin members are melted in the overlapping portion.
