QUALITY POLICY
Quality goals
Welding consistency: Ensure that the strength of the weld is stable and the weld core diameter meets the standard (such as ≥4√t, t is the plate thickness).
Equipment reliability: The life of key components (such as inverter modules and electrodes) meets the standard, and the failure rate is ≤0.5%/year.
Process adaptability: Supports welding of multiple materials (steel, aluminum, galvanized sheet) and different thickness combinations.
Energy efficiency optimization: The energy consumption per unit weld is reduced by 20%~30%, which meets the green manufacturing standards.
Manufacturing
Key component detection:
◦ 100% aging test of IGBT modules to ensure voltage resistance and heat dissipation performance.
◦ Electrode coaxiality error ≤0.02mm to avoid welding deviation.
Whole machine test:
◦ Continuous welding of 1000 points, monitoring current fluctuations (within ±2%).
◦ Repeatability of the pressurization system with a positioning accuracy of ±0.5μm.
Process monitoring
Intelligent feedback system: Real-time monitoring of welding current, voltage, and electrode pressure, and automatic compensation of parameter deviations.
Data traceability: Each device generates a unique ID to record production batches, test data, and maintenance history.
After-sales service
Quick response: Provide 24-hour remote diagnosis, and key components will be replaced within 48 hours.
Regular maintenance: It is recommended to calibrate the current output every 6 months and check electrode wear every 3 months.
