Abstract
The present invention relates to a method for evaluating an assembly by welding of parts made of thermoplastic materials, to a test piece and its associated uses, to an installation for implementing this method and to the associated welding system.
Claims12
A method for evaluating parameters of a method for assembly by welding, comprising:
- providing a test piece comprising at least two parts comprising thermoplastic materials;
- wherein at least one of the at least two parts is a perforated reference part comprising at least one perforation configured to allow for measurement of an internal temperature of the test piece;
- providing a welding installation comprising at least one heating element and at least one temperature sensor;
- heating a welding area of the at least two parts with the at least one heating element to cause welding;
- and
- measuring at least one internal temperature of the welding area at a level of the at least one perforation by means of the at least one temperature sensor;
- wherein the heating element and the at least one temperature sensor move in a welding direction D relative to the at least two parts during welding.
