Abstract

Laser welding of polymers is today a commonly used industrial technology. It has shown
obvious advantages compared to e.g. adhesive bonding in terms of higher productivity, better
quality and easiness for automation.
The ongoing development of lasers tailored for polymer welding in coordination with the
development of related absorbers added to the polymer materials provide the possibility of
joining transparent and non-transparent materials. The automotive industry, the medical
device industry and the electronic industry are just some of the areas where the technology is
widely implemented.
There is an increasing industrial interest in joining dissimilar polymers. To overcome
the challenges involved increased focus is set on the understanding of joining mechanisms,
morphology and molecular structure behavior. Also the understanding of resulting mechanical
and thermal properties is presently subject for research and development.
This paper presents some research results related to laser welding of various polymer
materials, including weld compatibility investigations related to the joining of different
polymers. Theory for bonding mechanisms, strength development, mechanical properties
testing and other analysis methods are also highlighted.
