Prior to annealing, cold-rolled steel coils require internal welding of the strip head to ensure coil integrity throughout the annealing process. This prevents internal loosening or shifting that may cause surface scratches or defects. Similarly, for finished coils, internal welding before packaging and shipment is critical to prevent strip displacement during handling and transportation.
Action:
We have developed specialized resistance spot welding equipment for steel coil applications, with the following key features:
- Capable of welding steel coils of various sizes and specifications.
- Integrated vision system for automatic detection and welding of coil joint positions.
- Equipped with a collision alarm system and strip-head support device to enhance operational safety.
- Includes a pneumatic balancing system.
Results:
Customer Benefits
- Significant reduction in scratch-related complaints during annealing or transportation
- Enhanced product consistency and appearance quality
