DIHAI AI Vision No-Teach Intelligent Welding Robot
DIHAI-W160 & DIHAI-W220 For Steel Structure, Shipyard & Offshore Heavy Plate Welding
Company Overview
DIHAI (Nanjing DIHAI) is a high-tech developer & manufacturer of AI autonomous welding robotic systems. Our core innovation: 3D laser vision + native AI multi-layer multi-pass welding algorithm. No robot teaching, no CAD drawing required. Scan workpiece → auto generate weld path → start welding. Specially built for non-standard thick plate workpieces in steel fabrication, shipbuilding and offshore industry.

Key Competitive Advantages
- No teaching, no CAD drawing: Biggest advantage vs FANUC/Yaskawa/KUKA traditional teach-playback robots, cut changeover time dramatically for non-standard workpieces.
- Native AI thick plate multi-layer multi-pass algorithm, specially optimized for ship & offshore heavy welding. Most AI welding competitors only support thin simple steel.
- All-in-one integrated system, easy deployment on existing workshop floor.
- Strong price advantage vs European & Japanese heavy welding robotic systems, shorter ROI for end users (12~20 months).
- White-label / OEM branding available for qualified overseas exclusive agents.
- Flexible after-sales cooperation model: local service handled by agent + DIHAI remote engineering support.
Target Customers & Partners
End users: Steel fabricators, shipyards, offshore construction workshops, bridge steel manufacturers.
Partner type: Exclusive regional agents, ship / steel automation system integrators, offshore EPC contractors.
