# Path Robotics: The $100M Bet on Autonomous Welding **Path Robotics**, the AI-powered welding robotics company, has raised **$100 million** in Series D funding led by **Matter Venture Partners** and **Drive Capital**, with participation from **Tiger Global** and **Addition**, bringing total capital raised to **$165 million**. As US manufacturing faces a catastrophic shortage of 400,000+ welders and rising labor costs, Path's autonomous welding robots use computer vision and AI to weld complex parts with zero programming—and manufacturers are adopting at record pace. ## The Skilled Welder Crisis ### Manufacturing's Most Critical Labor Shortage Welding is one of the highest-demand, hardest-to-fill jobs in American manufacturing—and the shortage is accelerating. **The Welder Shortage:** **Current Gap:** - **400,000+ welder shortage** in US (American Welding Society) - **360,000 welders needed** by 2027 to meet demand - **54% of welders** are over age 45 - **10% annual attrition** due to retirement - **Very few young people** entering trade **Why No One Wants to Be a Welder:** - **Physically demanding**: Kneeling, awkward positions, heavy equipment - **Dangerous**: Burns, fumes, eye damage, respiratory issues - **Hot and dirty**: 100°F+ environments, sparks, metal dust - **Perception problem**: Not seen as prestigious career - **Training gap**: Vo-tech programs underfunded - **Geographic mismatch**: Welders retire in Sun Belt, jobs in Rust Belt **Economic Impact:** **For Manufacturers:** - **$200K+ annual cost** per welder (wages + benefits + overhead) - **6-12 month hiring cycles** for skilled welders - **30-50% turnover** in some regions - **Production delays**: Can't ship if welds aren't done - **Quality issues**: Inexperienced welders = rework - **Lost contracts**: Can't bid on work without welders **Market Size:** - **$20B annually** spent on manual welding labor in US - **5B+ welds** performed annually in manufacturing - **45% of manufacturing** operations involve welding - **Critical to**: Automotive, aerospace, construction, shipbuilding, energy **Traditional Automation Limitations:** **Old-School Weld Robots (FANUC, ABB, KUKA):** - **Programming nightmare**: 40-80 hours to program one part - **Fixed paths**: Can't adapt to part variation - **High CapEx**: $150K-300K + months of integration - **Inflexible**: New part = reprogram from scratch - **Limited use cases**: Only for high-volume, identical parts - **<5% adoption**: 95% of welding still manual **Why Automation Failed in Welding:** 1. **Part variation**: Every part slightly different (tolerances, fixturing) 2. **Complex geometry**: Curves, angles, hidden joints 3. **Programming complexity**: Requires PhD-level robotics expertise 4. **Economic threshold**: Only makes sense for 1M+ identical parts 5. **Skilled integrator shortage**: Even fewer robot programmers than welders ## Path Robotics' Solution: AI-Powered Autonomous Welding ### Zero Programming, Full Autonomy Path Robotics' breakthrough is making welding robots that require no programming and adapt to any part. **The Path System:** **Hardware: Vision-Guided Robotic Welder** **Robotic Arm:** - 6-axis industrial robot (ABB, FANUC) - Welding torch end-effector - Precise motion control - Commercial-grade reliability **Vision System:** - Stereo cameras (3D perception) - Laser scanners (sub-millimeter precision) - Real-time depth sensing - Occlusion handling **Welding Equipment:** - MIG, TIG, or laser welding - Automated wire feed - Shielding gas management - Heat and arc control **Software: The AI That Changes Everything** **1. Part Inspection (No CAD Required)** - Robot scans the part with 3D vision - Builds complete 3D model - Identifies weld seams automatically - Measures gaps, angles, thicknesses - No CAD files needed **2. Weld Path Planning** - AI determines optimal weld path - Accounts for part geometry - Plans torch angle and approach - Optimizes for quality and speed - Handles complex joints (T-joints, lap joints, butt joints) **3. Adaptive Welding** - Real-time vision during welding - Adjusts for part movement or fixturing errors - Adapts to material thickness variations - Compensates for heat distortion - Self-corrects if path deviates **4. Quality Assurance** - Inspects weld in real-time - Detects defects (porosity, undercut, spatter) - Automatic rework if needed - Reports weld quality metrics - Continuous learning from outcomes **How It Works (Operator Perspective):** **Traditional Robot:** 1. Hire integrator ($50K-100K) 2. Create CAD model of part 3. Program robot path (40-80 hours) 4. Test weld, adjust, repeat (days) 5. Lock down part fixturing 6. Run production (pray nothing changes) 7. New part? Start over at step 1 **Total setup**: 2-4 months, $100K+ in engineering **Path Robotics:** 1. Place part in fixture 2. Tell robot: "Weld this" 3. Robot scans, plans, welds 4. Done **Total setup**: 5 minutes, zero programming **Key Advantages:** **Zero Programming:** - Any operator can use it - No robotics expertise required - New parts in minutes, not months **Adaptive to Variation:** -

As the welder shortage worsens (400K+ unfilled jobs) and manufacturers embrace automation, Path is positioned to become the category-defining company in AI-powered manufacturing. If Path can scale to 5,000+ robots over the next 5 years, capture 10-15% of the $20B US welding market, and expand internationally, the company could reach $500M-$1B in annual revenue and a $5-10B valuation. **The future of American manufacturing doesn't have enough human welders. Path Robotics is building the AI-powered robots that will replace them—and save the industry.**
