Description of the Related Art In recent years, there has been an increasing demand for higher quality resins in the fields of chemicals, food, semiconductor industry, biotechnology, chemical industry, housing, gas, etc. due to their chemical resistance and cleanliness. For example, polyfluoroalkoxy, Fluorine resins such as polyvinylidene fluoride and super engineering plastics such as polyphenylene sulfide and polyether ether ketone have come to be used as piping materials.

るなどの効果がある。The automatic welding apparatus for heat-weldable resin tubular parts of the present invention is an apparatus for abutting and welding a pair of heat-weldable resin tubular parts facing each other as described above in detail. A pair of clamp parts for respectively holding the pair of tubular parts, and an abutting part for abutting the end faces of the pair of tubular parts when holding the pair of tubular parts by the pair of clamp parts, respectively, The end surfaces of the pair of tubular parts clamped by the pair of clamping parts are flattened in a direction perpendicular to the axis of the tubular parts or are almost entirely mened from the outer circumference to the inner circumference. And a melting portion that melts the end faces cut by the cutting portion to substantially equal melting depths, the cutting portion, the abutting portion, and the cutting portion. The fusing part is arranged on the rotating disk at a predetermined interval in the rotation direction, and at least one tubular part melted by the fusing part is relatively disposed on the other tubular part side melted by the fusing part. Since all the steps for automatic welding can be continuously and smoothly performed by one unit, they do not require any troublesome skill. The melted portion can be formed thin, and each end surface of the pair of heat-weldable resin tubular parts can be uniformly melted by stable radiant heat without increasing the temperature of the melted portion, Moreover, since a pair of heat-weldable resin-made tubular parts can be automatically welded in a short time, there is an effect that power consumption is reduced.
