Abstract

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.
