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.
LAS-TRAC/E™
High-speed and high-accuracy seam tracking laser-vision system for laser welding, laser hybrid welding and laser brazing. LAS-TRAC/E™ is designed to perform real-time laser seam tracking of the laser welding joint to ensure perfect positioning of the laser welding spot within the joint. LAS-TRAC/E™ system handles complex seam trajectories and critical part variability. It is suitable for any weldable base metal from carbon steel to stainless steel, as well as highly reflective aluminum alloys.
DIGI-LAS-MDL/E™
The DIGI-LAS-MDL/E™ is an intelligent modular laser processing system. It integrates a dedicated high precision 3D 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 3D parts with either articulated robots or a multi-axes CNC machine.
