Obsidian™
Human-level intelligence,
embodied in automation.
Our Models
Weld World Model
knows what welding is.
The World's Most Accurate
Welding Simulator

Path’s Weld World Model is a neural network trained on high-fidelity, multimodal weld data. Over 8 years, our widely deployed fleet and internal data farm have generated tens of millions of welded inches of training data.
Unlike traditional welding simulators that approximate outcomes using simplified mathematical equations, our model learned to weld the way a human does: by welding, observing, and adapting — but with superhuman vision and at a massive scale.
Obsidian™
knows how to weld.
Reinforcement Learning Agent
Trained Inside the Weld World Model

Deployed at the edge, Obsidian™ was trained at a massive scale inside Path’s Weld World Model to master the welding craft.
Obsidian™ ingests real-time data from Path’s sensor stack to make real-time welding decisions seam by seam, just like a human would.
Pre-weld, during-weld, and post-weld data are captured to continuously improve the Weld World Model.
- 2 cameras + 4 lasers deliver 360° awareness around the torch
- Sub-millimeter point cloud generation
- Neural network-driven filtering rejects false reflections in real time
Sensor Stack
Metrology-grade optics built to survive welding environments allow Path's proprietary sensor stack to capture rich data before, during, and after welding.
