Abstract
The invention first relates to a method for welding at least two 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 parts; generating heat via said insert; wherein the insert moves in relation to the parts to be welded in a welding direction. The invention also relates to an installation adapted for implementation of this method.
Claims18
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 parts, said insert having a thickness of 5 mm or less;
- providing heat via said insert;
- wherein the insert moves in relation to the parts to be welded at the time of welding, in the 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.
