Solution Overview

Tab and cover welding are critical steps in EV battery safety — weld quality directly affects cell performance and safety. Traditional manual sampling cannot cover every weld and often misses hidden defects.

TSingley’s ultrasonic welding online quality monitoring system samples power, amplitude and frequency signature signals at high frequency through multiple channels, then applies a CNN convolutional neural network + VAE anomaly detection + rule engine three-way fusion model to judge quality in the instant of the weld: good welds pass, suspicious ones are intercepted on the spot, and defective welds trigger alarms with locked data — delivering zero-defect-escape, full-coverage online inspection.

Core Capabilities

🎯
Three-Way Fusion Verdict
CNN learns weld signatures, VAE captures anomaly distributions and the rule engine enforces critical thresholds — triple validation cuts missed defects and false alarms.
Real-Time Edge Inference
Millisecond verdicts during the weld cycle keep line takt untouched while defects are intercepted instantly.
📊
Full Data Traceability
Waveforms, features and verdicts for every weld are stored in full, enabling LOT/work-order-level traceability and quality analysis.
🔄
Continuous Model Improvement
Rule-engine-assisted labeling auto-flags unknown defects so the models keep improving through iteration.
