Issue Highlights:
Determination of material data in the ultrasonic range – Characterisation of temperature-dependent storage and loss moduli at a typical ultrasonic welding frequency of 20 kHz
In order to permit the simulative assessment of the weldability at an early stage in the development process of new ultrasonic joining components, a new approach was developed for determining the required frequency-depen...
Deformation of pin-like structures in the joining process in order to produce form-fit multimaterial joints
Multimaterial combinations are playing an ever more decisive role and posing great challenges for traditional joining procedures. Innovative procedures are necessary in order to extend the material spectrum. Within the f...
Effects of different heating strategies on infrared-heated polyphthalamides
Infrared welding is one of the contactless joining procedures and is very suitable for welding technical thermoplastics. In this respect, the material is plastified by radiation. Above all, the heating strategy can be de...
