摘要
A welding device includes a compressor configured to compress a welding part and its adjoining surfaces of thermoplastic resin articles (2a, 2b) in directions perpendicular to the axis of a core (1), and a heater, and is configured such that: the surface of the welding part of the thermoplastic resin articles is compressed with a predetermined pressure by the compressor, the compression of the thermoplastic resin articles is then continued to extend a compressed region along the axis of the core without changing a relative position between the compressor in the compressed region and the surface of the welding part of the thermoplastic resin articles, the welding part of the thermoplastic resin articles is heated and welded by the heater, and after the welding, the pressure applied by the compressor is lowered to stop the compression of the thermoplastic resin articles such that the thermoplastic resin articles fitted on the core can be taken out of the welding device.
