Robotic Welding Station for Excavator Track Beams | AGR Robotics

The excavator track beam forms the main support of the undercarriage system, connecting the track frames and absorbing constant vibration and heavy loads.

To ensure strength and long-term reliability, AGR Robotics developed a robotic welding station designed for thick-section, multi-angle welding of track beam assemblies.

Equipped with servo-controlled positioners and high-current CO₂ arc welding, the system achieves deep fusion with precise control of heat input.

Its adaptive seam tracking technology ensures consistent penetration even under material tolerance variations.

By replacing manual welding with automated precision control, the system enhances throughput, consistency, and fatigue resistance — providing a robust, high-efficiency welding solution for modern excavator undercarriages.
