ABSTRACT:
A method of welding thermoplastic resin with a high frequency welder, comprising the step of: putting an exothermic object to generate heat and an adherend made of thermoplastic resin not to be molten when high frequency waves are applied, between electrodes of a high frequency welder and thereafter generating high frequency waves between the electrodes. The method of the present invention enables to weld thermoplastic resin having a low dielectric loss which can not be welded with a high frequency welder.
