In the process of laser plastic welding an infrared laser beam is passed through an upper laser transmissive layer to a lower laser absorbing layer. The energy absorbed at the weld interface is conducted from the lower layer to the upper layer through conduction as the parts are clamped tightly together.
Hybrid laser welding is the same concept, however, in addition to the laser radiation a high-powered halogen lamp assists the laser. The polychromatic radiation from the halogen lamp helps pre-heat and soften both the upper and lower layer. This makes for faster welding, less stress on the part and stronger welds.
The process of laser plastic welding involves passing laser radiation through an upper transmissive layer to the surface of the lower absorbing layer. The absorbed radiation creates heat and contact between the two joining partners allows for melt and a weld at the interface.

Designed for heavy industrial use the, LPKF LQ-Power is a workhouse, but still lives up to the “velvet hand” precision laser welding is know for. The rotary indexing table allows for parts to be loaded during welding, reducing downtime.
Laser plastic welding of car tail lights is the next big thing in automotive manufacturing for good reasons including: durable and hermetic seals, aesthetically pleasing weld seams, flexibility and cleanliness. Pushing this already ground breaking technology even further, LPKF Laser & Electronics has introduced a hybrid welding system.
