1. A method for welding at least two rigid parts comprising a thermoplastic material and having respective surfaces to be welded, comprising:
inserting an insert between the surfaces to be welded of the two rigid parts, said insert having a thickness of 5 mm or less;
providing heat via said insert;
wherein the insert moves in relation to the two rigid parts to be welded at the time of welding, in a welding direction; and
wherein the insert comprises an induction-sensitive material, and the heat of the insert is provided by the generation of a magnetic field by at least one inductor.
