Abstract
A method for welding at least two parts including a thermoplastic material and having respective surfaces to be welded, including: inserting an insert between the surfaces to be welded of the two parts; generating heat via the insert; wherein the insert moves in relation to the parts to be welded in a welding direction. Also, an installation adapted for implementation of this method.
Claims13
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.
An installation for welding at least two rigid parts comprising a thermoplastic material and having respective surfaces to be welded comprising:
- a support to hold the two rigid parts to be welded;
- an arm comprising at its end portion a heating insert having a thickness of less than 5 mm, configured to be inserted between the surfaces to be welded of the two rigid parts;
- the insert being configured to move in relation to the two rigid parts to be welded at the time of welding, in a welding direction;
- and
- wherein the heat-generating device is at least one inductor, and said insert comprises an induction-sensitive material.
