1. Industry Pain Points Analysis for Welding Robots
The welding robot industry currently faces these core challenges:
- Technical Bottlenecks: Poor adaptability to non-standard welding scenarios, traditional gearboxes with insufficient precision (±0.1mm or more) leading to unstable weld seam quality
- Low Domestication Rate: Core transmission components rely on imports, accounting for 30%-40% of equipment costs
- Poor Environmental Adaptability: Service life reduced by 30%-50% in harsh conditions like high temperature (>80℃) and dust
- Slow Response to Non-Standard Requirements: Long customization cycles for special installation spaces (e.g., medical robot joints) and irregular structures
2. Core Requirements for Welding Robots
- High Precision Transmission: Repeatability positioning accuracy ≤0.03mm, backlash <1 arc minute
- High Rigidity Structure: Impact resistance torque ≥8000Nm, vibration suppression efficiency >35%
- Environmental Adaptability: Operating temperature -40℃~150℃, IP67 protection rating
- Compact Design: Joint space occupancy reduced by 70%, support for miniaturization (diameter ≤30mm)
- Rapid Delivery: Standard orders delivered within 3 weeks, small batch customization supported within 72 hours
3. Industry Status and Technical Trends
According to 2025 industry data, the Chinese welding robot market size reached 16.6 billion yuan, but domestic substitution rate is less than 30%. Smart welding robot penetration is rapidly increasing in fields like steel structure (60%) and shipbuilding (45%), but core transmission components still rely on imports. With policies like the "Implementation Plan for Manufacturing Reliability Improvement," the window for domestic substitution is now open.
