Robotic Welding Station for Excavator X-Frames | AGR Robotics

In heavy construction equipment, the excavator X-frame serves as the foundation of the entire undercarriage structure, bearing high torsional and dynamic loads during operation.

To meet the strict requirements for strength, dimensional accuracy, and consistency, AGR Robotics developed a dedicated robotic welding station tailored for X-frame assembly.

This system features synchronized multi-axis robots, adjustable positioners, and laser-guided seam tracking to ensure complete weld coverage and superior joint quality.

The adaptive welding control system continuously adjusts parameters based on weld path feedback, ensuring deep penetration, minimal deformation, and repeatable precision.

By replacing traditional manual welding, this automated solution greatly improves throughput, reduces human error, and guarantees long-term structural reliability — an ideal system for excavator chassis and undercarriage manufacturing.

AGR Robotic Welding Solution for Excavator X-Frames | AGR Robotics：

AGR developed a robotic welding station specifically for the welding of excavator X-frame structures, combining high-load joint precision with fully automated undercarriage assembly welding.

The system achieves superior performance and stability for heavy equipment chassis manufacturing.

Key Features:

• Dual Panasonic TM-1800 G3 welding robots enable coordinated welding on multiple X-frame seams simultaneously.

• ±0.08 mm positioning accuracy with servo-controlled positioners ensures precise alignment of large structural components.

• Laser seam tracking and automatic torch adjustment deliver stable arcs and uniform penetration across complex geometries.

• Welding process powered by YD-500GL5 high-speed arc systems for deep fusion and reduced spatter.

• Cycle time reduced by 25%, improving overall production efficiency and welding consistency for heavy-duty undercarriages.
