Abstract
The electronic and automobile industries have a growing
interest on laser welding of polymers. Laser welding of
polycarbonate has been widely studied in numerous
different occasions. Novel ways for creating stronger and
visually better welds are continuously studied. The need
for short welding times and narrow welds gives a
challenge for quasi-simultaneous laser welding: The welds
have to be as strong as the base material when weld
widths are from 0.2 mm and up but the welding times must
be less than 1 second. This paper examines the effect of
clamping force during welding and the possibilities to
use a ridge, typical for ultrasonic welding, on top of
the absorbing part to improve the weld properties.
Depending on the welded part there is a need for high
clamping forces in order to close all air gaps caused by
inaccuracies of and variation on injection molded parts.
Results on weld widths on different clamping forces with
and without the ridge are presented. Outcome of the
research is discussed based on these results. (6 refs.)
