OTC DAIHEN FD-B6 Zero-Interference Built-in Motor Welding Robot
The OTC DAIHEN FD-B6 is a compact, ultra-streamlined 6-axis industrial welding robot engineered for zero-interference automation. Combining a standard 1,438 mm working radius with a 6 kg payload capacity, the FD-B6 distinguishes itself by embedding its Axis 5 and Axis 6 AC servo motors directly within the arm housing alongside coaxial through-arm cable routing. This clean, snag-free architecture eliminates external cable loops and motor protrusions, allowing the robot arm to execute high-speed welds inside confined automotive sub-frames, exhaust manifolds, and precision tubular structures without risk of collision.

🔧 Engineering & Integration Guide
- Zero Blind-Spot Welding: The embedded motor structure removes exterior bulk from the wrist, granting programmers complete freedom to approach weld joints from tight, aggressive angles.
- Enhanced Cable Longevity: Because coaxial power and gas lines are completely enclosed and shielded from UV radiation, weld spatter, and mechanical scraping, consumable cable replacement intervals are extended by up to 300%.
- Offline Simulation: The clean outer cylindrical contour of the FD-B6 simplifies offline 3D CAD CAD/CAM programming and collision detection modeling, reducing onsite commissioning time.
