Arc 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.
AUTO-TRAC/PWP™
AUTO-TRAC/PWP™ is the most compact seam tracking system on the market. It can be easily retrofitted onto any existing hard welding automation machine that either has no joint tracking capability or is presently using a mechanical probe. The system is equipped with a POWER-CAM™ laser-sensor with an embedded color video camera which can be used for welding process monitoring and remote teaching.

MICRO-TRAC™
Very compact, high-speed 3D laser-vision system for robotic arc welding and other industrial robotic processes. Compatible with different welding processes (GMAW, GTAW, etc., with pulsed or high-frequency power source). Reduces process instability and spatter and improves the weld quality by precise positioning of the wire in the joint. Designed for robotic welding processes and includes all the necessary software to deal with all types of welding materials such as carbon steel, stainless steel, and aluminum alloys.
MICRO-TRAC-CO-S™
Intelligent 3D vision system for joint tracking & adaptive process control. The MICRO-TRAC/CO-S™ vision system is designed for special purpose welding machines and ready for customer’s actuators (not included) using CANopen LXM28A Schneider single motion servo drive systems (not included).
POWER-TRAC 4.0™
POWER-TRAC 4.0™ system which is the product offered by SERVO-ROBOT for robotic real-time seam tracking, offline seam finding and adaptive control. In seam tracking mode, the tool trajectory is modified continuously to compensate for part position variation. In seam finding mode, parts and/or features position is measured first to offset the robot path accordingly.
