Tube-to-Tubesheet Welding

Performance Characteristics and Advantages
1.Technical Documentation:
"The vision-guided system achieves ±0.1mm alignment accuracy by compensating for tube sheet hole positional errors, significantly reducing rework rates in heat exchanger manufacturing."
2.Flexible Production: Rapid Task Switching
When switching product models, simply import new drawings to automatically adjust welding paths, eliminating reprogramming or tooling replacement (reducing changeover time by over 60%).
3.Efficiency Improvement
(1) Automated Path Planning
Technical Implementation:
Generates optimal welding sequences by analyzing CAD drawing data, significantly reducing non-productive tool movement (improves welding speed by 20%-30%)
(2) Continuous Operation Capability
Industrial Advantages:
Enables 24/7 production with stable quality, ideal for high-volume components like power plant boiler tube sheets
4.Quality Consistency Assurance
Intelligent Parameter Matching: Automatically invokes welding parameters (current, speed, oscillation pattern) based on material, thickness, and other specifications annotated in the drawings, eliminating manual operation variations
5.Cost Optimization
Reduced rework rate:
Vision-guided correction achieves welding defect rate below 1% through real-time deviation compensation, significantly reducing material and labor-hour waste
Labor savings:
A single unit replaces 2-3 senior welders, achieving long-term labor cost reduction through 24/7 automated operation
6.Technical Scalability
Digital integration:
Drawing data directly interfaces with MES/PLM systems (Manufacturing Execution System/Product Lifecycle Management), enabling digital management of welding parameters and quality traceability
Typical Application Scenarios
Nuclear Tube-Sheet Seal Welding:
Zero-defect deep-hole welding requiring vision-guided assurance of no missed welds.
Multi-Material Welding for Chemical Equipment:
Automatic drawing recognition of different material zones with parameter switching.
Repair & Remanufacturing:
Scanning worn tube-sheets to generate repair drawings, guiding precision rewelding.
Technology Integration:
Through deep fusion of drawings and vision guidance, such systems directly translate design intent into highly reliable welding outcomes – a key enabling technology for high-end manufacturing upgrade.
