FANUC Multi-Arm Welding Robots Weld Loose Brackets Onto Exhaust Assembly

In this robotic welding application case study demonstration, two FANUC M-20iA robots with iRVision 3DL find loose brackets in part trays, then pick and attach them to an exhaust assembly.

The M-20iA robots manipulate the exhaust system while two ARC Mate 100iC robots simulate coordinated welding of the brackets. The ARC Mate 100iC robot with iRVision Error Proofing checks the brackets for weld seam presence of the weld nuts.

This system demonstrates the flexibility of the robot to pick and load the parts onto the assembly, and position and coordinate the welding, which improves quality. Quality control is enhanced through self inspection of the final product, reducing re-work and overall operating costs. All four robots are utilizing the Multi-arm option which allows them to all operate from one CPU and one Pendant. This system demonstrates the simplest and most cost effective tooling solution.
