Robotic Weld Tip Degradation
In high-volume automotive assembly, electrode tip wear leads to “cold welds” and structural compromises. We implement Acoustic Emission (AE) sensors coupled with Convolutional Neural Networks (CNNs) that analyze the high-frequency sonic signatures of every weld. By transforming audio signals into Mel-spectrograms, our models detect the exact micro-moment an electrode requires dressing, reducing scrap rates by 18% and preventing catastrophic line stoppages.
