Recently, a European client made a special visit to HAIFEI Intelligent Equipment's production base for an in-depth two-day technical inspection focused on seam welding machine specialized for new energy battery casings. The evaluation centered on the equipment's welding performance with lightweight materials such as aluminum alloy and galvanized steel. Both parties engaged in thorough discussions regarding welding process optimization, production line integration solutions, and adaptation to the European market, reaching a preliminary consensus on customized cooperation.

Record of Technical Inspection
The client placed particular emphasis on validating three core systems:
- Adaptive Pressure Control System: Utilizes Swiss Kistler pressure sensors to monitor welding pressure fluctuations in real time and automatically compensate, ensuring pressure control accuracy within ±1.5%.
- Temperature Monitoring Module: Integrates infrared temperature measurement with a closed-loop cooling system to maintain the welding zone temperature within the optimal range of 280–320°C.
- Online Weld Quality Inspection: Employs a machine vision-based real-time defect detection system capable of identifying welding defects larger than 0.1 mm.
Detailed Technical Advantages of the Equipment
High-Precision Welding Platform
- Utilizes HIWIN linear guides and servo systems, achieving repeat positioning accuracy of ±0.03 mm.
- Welding pressure range: Continuously adjustable from 200 N to 6000 N.
- Maximum welding thickness: 3.5 mm for single-layer and 6 mm for double-layer (aluminum alloy).
Intelligent Control System
- Equipped with HAIFEI's independently developed HWCS 3.0 welding control system.
- Supports storage and one‑call retrieval of 200 sets of welding parameters.
- Features weld data traceability, complying with IATF 16949 quality system requirements.
Energy Efficiency Optimization Design
- Incorporates IGBT high-frequency inverter technology, achieving overall machine efficiency of 92%.
- Saves 28–35% energy compared to traditional AC rolling welding machines.
- Standby power consumption < 500 W.
IV. Cooperation Progress and Outlook
The European client stated, "We evaluated five suppliers, and HAIFEI's equipment demonstrated the most outstanding performance in welding stability tests. Particularly, its adaptive pressure control system effectively addresses deformation issues in thin‑sheet welding."
Both parties have now initiated technical agreement discussions and plan to commence trial production of the first batch of samples next month. A HAIFEI representative emphasized, "This is more than just an equipment purchase. We look forward to establishing a long‑term technical partnership with our European counterparts."
