PURPOSE:To make it possible to weld a thermoplastic resin having small dielectric loss, by putting an adherend, which consists of an exothermic body generating heat by a high-frequency welder and a thermoplastic resin that is not molten by said welder, between electrodes and generating a high-frequency current between said electrodes. CONSTITUTION:As an exothermic body generating heat by a high-frequency welder, chlorosulfonated polyethylene, chlorinated polyethylene, and also ethylene-vinyl acetate copolymer with 8-35wt.% of vinyl acetate are used. As a resin for adherend, the thermoplastic resin with small dielectric loss, which cannot be welded directly by using a high frequency welder, for example such as polyethylene, polypropylene, etc., is applied. Exothermic bodies 3, 4 and adherends 5, 6 are so lightly pressed with electrodes 1, 2 that said adherends 5, 6 are not broken when welding, and a high-frequency current is generated between said electrodes 1, 2 and said exothermic bodies 3, 4 generate heat. In such a way said adherends 5, 6 are heated, release heat and are molten to be integrated. |
