Description
Heavy-Duty Multi-Gantry Robotic Welding System
The JISI Heavy-Duty Multi-Gantry Robotic Welding System integrates multiple welding robots into a heavy-duty gantry structure for simultaneous and high-efficiency automated welding of large and long workpieces.
Multiple robots can operate simultaneously on different weld seams or work areas, helping increase production capacity and reduce overall welding cycle time. The heavy-duty gantry structure provides extended working coverage and stable robot positioning for large-scale metal fabrication.
The system supports MIG/MAG welding and can be configured with arc tracking, laser seam tracking, welding positioners and customized fixtures according to specific production requirements.
Designed for high-volume and multi-station production, the system is ideal for steel
structures, construction machinery, heavy equipment and large metal fabrications. Gantry dimensions, robot quantity and welding configurations can be customized according to the customer’s workpieces and production capacity.
