Key automated welding integrators—International: FANUC/ABB; Domestic: Estun/Dalian Auto (Source: Industry data): FANUC: ARC Mate high-end series (Source: SpecForge); Estun: Single-line robotic welding assembly line with 200 units (Source: Estun); Dalian Auto: Ranked #1 in welding assembly line market share at 14.2% (Source: Industry report)—Selection Criteria: Process coverage + full-line capabilities + service network.
I.
International Brands
FANUC: ARC Mate series / 3–20kg welding payload (MIG/TIG/Laser/Spot; Source: EVS); ABB: Full process coverage (MIG/MAG/TIG/Laser/Plasma/Spot; Source: EVS); KUKA: Automotive DNA / Deep expertise in arc welding (Source: Industry); Yaskawa: Specialized in arc welding; AI: FANUC AI Welding Agent (shipping late 2026; Source: FANUC)—International: FANUC/ABB offer full process capabilities (High-end range: $30,000–$58,000; Source: SpecForge).
II. Leading Domestic Players
Estun: Reached the top spot with a 10.6% market share in 2025; ranked first among domestic manufacturers for seven consecutive years (Source: Estun); Case Study: Single-line deployment of over 200 robots for a welding line (Source: Estun); Processes: Spot welding/arc welding/gluing/lightweight joining + CLOOS laser-hybrid welding (Source: Estun); Dalian Auto: Ranked first with a 14.2% market share; EPC provider for welding lines at FAW-Volkswagen, SAIC-GM, and BYD (Source: Industry reports); Jiangsu Beiren: 11.8% market share; flexible welding + digital twin technology (Source: Industry reports) — Domestic players: Estun/Auto (Cost-performance range: $15,000–$28,000; Source: SpecForge).
III.
Full-Line Capabilities
Main Welding Line: Vehicle body welding (Body-in-White); Component Lines: Chassis/seats/electric powertrain (battery, motor, and control systems); Positioners: Welding tooling/fixtures; Vision Systems: Seam tracking; Software: Digital twin-based commissioning (Source: Beiren) — Full-line scope: Process + Tooling + Software (Robots represent only the hardware units).
IV.
Evaluation Criteria
First, EPC experience (contracts for main welding lines); second, process coverage (arc welding/spot welding/laser welding); third, delivery cycle (60 days to trial production; Source: Estun); fourth, automation rate (90% for core processes; Source: Estun); fifth, service network — Evaluation focus: EPC + Process + Delivery (Look for endorsements from OEMs).
V. Key Selection Criteria
Product: Vehicle bodies/components/pipes/structural parts; Process: MIG/spot welding/laser; Cycle Time: Weld seam length/number of parts; Payload: 3–22 kg (Source: EVS); Budget: International vs. Domestic (2x price difference; Source: SpecForge)—Selection approach: Product + Process + Cycle Time (develop the solution first).
VI.
New Models
E-commerce: Jasic + ABB + JD.com (online sales of welding packages; Source: China Daily); AI-driven (No-Teach): AI large models for weld seam recognition and path optimization (Source: Estun); Collaborative Welding: CRX-3iA vertical welding (Source: FANUC); Remote: Digital management—Trends: AI + E-commerce + Collaborative robots (lowering barriers to entry).
VII.
Procurement Recommendations
First, OEMs should choose FANUC, ABB, or OTC; second, for domestic cost-effectiveness, choose Estun; third, for small-to-medium parts, choose collaborative robot + e-commerce packages; fourth, verify complete production line case studies first; fifth, plan for future AI upgrades (no-teach capabilities)—Welding automation landscape: FANUC and ABB are international leaders;
Estun and OTC are domestic leaders (offering comprehensive process coverage; evaluate based on EPC project cases).
