摘要： Described is a heating device for thermally connecting a pipe, which has a first plastic material, to a bushing, which has a second plastic material, and which surrounds at least a section of the pipe, wherein an inductively heatable heating means is located between the pipe and the bushing and/or integrated in the pipe and/or the bushing. The heating device has a coil arrangement, which is excitable by a generator, and which has a first coil, which has at least one complete winding within a first cross-sectional area, and a second coil, which is electrically coupled to the first coil, and which has at least one complete winding within a second cross-sectional area. The first cross-sectional area is different from the second cross-sectional area. Furthermore, a heating system having such a heating device as well as a method for thermally connecting a pipe to a bushing are described.

摘要： Described is a heating means for thermally connecting two objects each having a plastic material, wherein, during the connecting, a first inner object is surrounded at least partially by a second outer object, and the heating means surrounds the first inner object at least partially along a complete circumferential course around the first inner object, and is located between the first inner object and the second outer object. The heating means has a ribbon-type structure. The ribbon-type structure has an auxiliary heating material, which is inductively heatable, wherein the auxiliary heating material is spatially distributed or arranged along the circumferential course such that an electrical conductivity is interrupted at at least one position along the complete circumferential course around the first inner object. Further described are an arrangement and a system each having such a heating means as well as a method for thermally connecting two plastic objects.

摘要： Described is a heating means for thermally connecting two objects each having a plastic material, wherein, in the connecting, a first inner object is surrounded at least partially by a second outer object, and the heating means is located between the first inner object and the second outer object. The heating means has a ribbon-type structure, in which a plurality of openings is formed. These openings are dimensioned such that molten-on plastic material of the first inner object and/or of the second outer object can intrude and can connect to molten-on plastic material of the respective other object. Alternatively or in combination, the openings are filled with a plastic material, which can connect to molten-on plastic material of the first inner object and/or of the second outer object. The ribbon-type structure has a ferromagnetic material, which is inductively heatable and which has a Curie temperature that is lower than 460° C. and/or that is adapted to the melting temperature of the first inner object and/or of the second outer object. There is further described a welded arrangement as well as a welding system having such a heating means as well as a method for thermally connecting two objects each having a plastic material.
