Lasers Shine For Thermoplastic Welding

From Dukane Intelligent Assembly Solutions
 

 
Unlike laser welding of metals that focuses light on a joint edge, thermoplastics use a through-transmission technique. Here, laser light passes through a part that is transparent to the laser wavelength (typically near infrared) and is absorbed by a part filled with carbon black or other colorant. The absorbent part melts and conducts heat to the transmissive part, welding the two together.
