The invention discloses a welding quality detection method and device and a computer readable storage medium, and the welding quality detection method comprises the steps of obtaining and classifying source sample data of a to-be-welded object in a laser welding process, and forming a basic sample data set and a test sample data set; respectively inputting the basic sample data set and the test sample data set into a convolutional neural network for screening processing to obtain basic category features and test category features; inputting the basic node features into a graph neural network for processing to obtain basic edge features, and forming a fully connected graph; updating the basic node features and the basic edge features through a full-connection graph updating algorithm to obtain network node features and network edge features, and forming a training model; and inputting the test category features into the training model to obtain a quality evaluation result. The welding quality can be automatically evaluated in real time in the laser process, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a welding quality detection method and its device, and a computer-readable storage medium. Background technique [0002] With the rapid development of laser welding technology, laser welding processing is widely and deeply used in the fields of aerospace, automobile manufacturing and consumer electronics. On the automatic production line of laser welding, there are often adverse factors that affect the yield rate, but the real-time welding quality of the product cannot be known and processed in a timely manner, resulting in low production efficiency. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a welding quality detection method and its device, and a computer-readable storage medium, which can automatically evaluate the welding quality in...
