<P>PROBLEM TO BE SOLVED: To provide a method of IR welding method showning good welding results even in cases involving thick polyolefin resins (PE, PP) and polyfluorohydrocarbon resins. <P>SOLUTION: The method comprises polymerizing two or more thermoplastic resin members 3 onto a support 1, polymerizing an IR transmissive solid 5 to form a polymerization aggregate and irradiating the polymerization aggregate with a CO-source IR beam 11 from the side of the IR transmissive solid 5. Because a boundary temperature of the thermoplastic resin member in contact with the IR transmissive solid decreases relatively, an area of a higher temperature can be generated within the aggregate by utilizing the penetrated IR energy. A deterioration in surface property due to thermal damage in the IR-beam-irradiated surface can be thereby controlled, enabling formation of a heated/cooled welded layer in a short time. <P>COPYRIGHT: (C)2009,JPO&INPIT |
