Path Robotics Announces Obsidian - Foundational AI Model for Welding
COLUMBUS, Ohio — September 8, 2025 — Path Robotics, the leader in AI-powered autonomous welding technology, today announced Obsidian™, the first purpose-built foundational AI model for welding. Trained on tens of millions of welded inches, Obsidian represents Physical AI for Welding—a breakthrough that brings true machine intelligence to metal fabrication at a critical moment for American manufacturing.
More than 60 years after the first industrial robot went to work on a factory floor, 80% of welding is still done manually. The American Welding Society projects the US will need 320,500 new welding professionals by 2029—approximately 80,000 jobs to be filled annually—from a labor pool that simply does not exist. Traditional robotic welding has failed to close this gap because real-world parts are not perfect: fit-up varies, joints wander, and heat distorts large weldments. Traditional automation excels at consistency but cannot adapt to the messy reality of most manufacturing environments.
Obsidian changes this equation. The system uses a proprietary vision system to scan every welding seam using lasers and optics. This data is fed to Obsidian to develop the weld and path plan in real time. Once welding begins, the system monitors the weld pool and seam to compensate for heat distortion as the weld progresses. The result is consistent weld quality without the traditional burden of fixturing parts to perfection or reprogramming every time the part changes. In simple terms: Obsidian is the autonomy layer, the robot arm is the actuator. Obsidian decides what to weld, where to weld, and how to weld—then generates and adjusts robot motion as conditions change.
See Obsidian Live at FABTECH 2025
Path Robotics will be showcasing Obsidian and demonstrating its capabilities this week at FABTECH 2025 in Chicago, IL. FABTECH is North America's largest metal forming, fabricating, welding, and finishing event, and Path's booth will feature live demonstrations of Obsidian-powered welding systems handling real-world variation—high-mix production, multi-pass welding, and imperfect parts—without constant reprogramming.
“Obsidian represents a fundamental shift in how robotic welding systems understand and interact with the physical world. We've built a foundational model that truly understands welding—not just the physics, but the craft. This is the technology that will help solve the skilled labor shortage in manufacturing.”
Key Capabilities of Obsidian
True Autonomy: See, understand, adapt. Obsidian-powered systems scan every seam, plan every weld, and adjust in real time—no brittle code, no constant reprogramming.
Unmatched Agility: Perfect welds from imperfect parts. Handle high-mix, low-volume production with the same efficiency as high-volume runs, thriving where traditional robots fail.
Continuously Smarter: Learns from every weld. Each Path welding cell adds real production data, improving the model and delivering updates that raise quality and speed across the entire fleet.
Welding bottlenecks production across heavy equipment, energy, aerospace, agriculture, and the critical infrastructure that powers data centers and the grid. Obsidian helps close the labor gap, boosts throughput, lets skilled welders focus on the toughest jobs, and keeps production running when the lights are off.
