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™ 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.

The POWER-TRAC™ family of seam trackers includes sensors capable of precisely following any weld joint in combination with all welding processes and robots. In addition, full adaptive control is available to help compensate for part fit-up and maintain the desired welding speed and quality.
