METHOD OF WELDING RESIN AND RESIN WELDING APPARATUS

摘要

In a resin welding apparatus (1), there is carried out a method of resin welding comprising bringing a resin member (M1) and a resin member (M2) into contact with each other, irradiating a weld predetermined area (R) of a contact plane (S) between the resin member (M1) and resin member (M2) with laser beams so that the resin member (M1) and resin member (M2) are melted on the contact plane (S) and, in this situation, sequentially increasing the intensity of laser beams by zones different from each other within the weld predetermined area (R).
