In order to deal with the problem of defect detection of welding spot on steel plate surface, an improved ResNet feature extraction method is proposed by embedding Squeeze and Excitation (SE) module, then the XGBoost classifier is combined to achieve reliable welding spot defect detection. The experimental results show that the proposed algorithm has achieved remarkable improvement in main indexes such as accuracy, precision and F1 score, the recall rate reaches 97%, which is of great significance for further industrial applications.
