The Coherent ExactWeld IP is a laser-based polymer welding tool that integrates easily into manufacturing production lines and delivers trouble-free operation. The modular architecture of the ExactWeld IP makes integration straightforward, with support for pallet conveyors, rotary tables, or robot arm parts supply. The ExactWeld IP laser welding system delivers reliable, consistent welds by combining closed loop monitoring of part collapse height during laser welding, ultra-stable mechanical construction, and a high reliability Coherent diode laser source. Usability features such automatic exchange of tooling jigs which are RFID tagged ensure the ExactWeld IP laser welding system always keeps track of the correct laser welding job. The Coherent ExactWeld IP tool is the simplest way to implement high volume, reliable polymer welding into manufacturing production lines.
