Machine vision in the inspection of welding spots and rods.  

In structural assembly processes, every weld point matters. A defect in a bead can compromise the integrity of the entire car body.  

Today, the most advanced manufacturing plants are incorporating computer vision systems specifically designed for the inspection of spot welds and continuous weld beads, with the goal of detecting imperfections automatically, accurately, and without physical contact.  

How does it work?

1.Real-time image capture:  

  • Industrial cameras are installed along the production line.  
  • They capture images of areas where sealant is applied (e.g., doors, hoods, body joints).  

2. Structured lighting and advanced technology:  

  • Optimized lighting (such as laser or LED) is used to maximize sealant contrast.  
  • This allows for the detection of even the smallest details, even under challenging factory conditions.  

3. Processing with Artificial Intelligence / Computer Vision:  

  • Software analyzes the images in milliseconds.  
  • It detects anomalies such as missing sealant, excess material, bubbles, discontinuities, or misalignment.  

4. 100% automatic verification:  

  • Inspection is carried out without human intervention.  
  • Ensures complete traceability of the process.  

5. Visual interface for operators and quality control teams:  

  • Results are displayed clearly with images and alerts.  
  • The system can be integrated with the plant’s MES to generate reports and statistics. 

6. Continuous improvement and reduction of rework:  

  • Reduces the cost of poor quality.  
  • Enables real-time adjustments to prevent recurring errors. 

Benefits

  • Early defect detection before entering the paint shop  
  • Reduction in rework and line stoppages  
  • Weld bead analysis (MEP)
