Laser Seam Tracking
Seam Tracking, also known as Joint Tracking, involves real-time tracking just ahead of where the weld is being deposited. This allows for not only robot or machine trajectory shifts, but also adaptive control such as adjustments to voltage, wire feed, or travel speed to change weld bead formation.
The DIGI-LAS/MDL™ is an intelligent modular laser processing system. It integrates a dedicated high precision 3-D laser vision system for tracking and weld inspection to an industrially proven laser beam delivery head together into one compact rugged package that offers the perfect solution for the adaptive control of high speed welding machines or robotic laser welding systems. This system has a new generation control unit capable of performing both tracking and inspection functions simultaneously. It includes the capability of welding curved joints and complex 3-D parts with either articulated robots or a multi-axes CNC machine.

The AUTO-TRAC/LW™ is a complete solution for joint tracking and adaptive process control designed for laser and laser hybrid welding processes. This fully integrated standard system includes the laser-sensor, slides, controller, teach pendant and software, and is available for any joint preparation ranging from sheet metal to heavy plate.
