Surface temperature monitoring during contour laser welding of plastic

Welding of plastic parts is nowadays a very used technology in the industry for permanent joining parts together. 
There are several types of plastic welding technologies: hot body welding, hot gas, friction and ultrasound but also laser welding. 
Laser beam welding is advantageous for welding very small and narrow plastic parts due to the size of the laser beam. 
When placing several laser beams side by side we can create any shape and size of the welded contour. 
The laser beam passes through a transparent part of the plastics and stops at the base part. 
At this point, the joint begins to heat until the two parts are joined together. 
The process needs to be monitored to maintain a constant and long-term weld quality.
