The 3I welding systems consist of control and laser banks. It is a free-standing controller, designed to interface with a single 2000X actuator and up to four Radiance laser banks capable of delivering up to 500 Watts of laser power. This unit features an internal chiller for laser cooling.

Branson Laser assembly systems use a process called Simultaneous Through Transmission Infrared welding (STTIr). The process passes laser radiation through one plastic component (transmissive component), and the energy is absorbed by the mating component (absorptive component). This absorption results in the heating and melting of the interface, and with the application of a controlled clamp force the parts are joined. The major breakthrough in Laser technology is the ability to illuminate the entire welding surface simultaneously as compared to other techniques that rely on scanning of the weld joint.
