Laser Welding

Laser welding of thermoplastics joins two parts with no adhesive, no consumables and no particulate, provided the resin pair, the colorant package and the joint design let the beam reach the interface. The articles in this topic explain through-transmission laser welding, how to select resin pairs and carbon black or laser-transparent blacks, clear-to-clear welding, the additives that make a resin weldable, and how laser welding compares with ultrasonic and vibration welding on joint design, cycle time and cost. The laser plastic welding services page covers materials, process development and system integration.
