Development of Quality Criterion of Spot Welding by Results of Acoustic Emission Monitoring

This article discusses the design of algorithm for processing of acoustic emission signals. It will allow elaborating the criteria for assessing the quality of resistance spot connection. The problem can be solved by using the convolution method, which can detect the exemplary temporal process in the analyzed signal. We synthesize two processing algorithms of acoustic emission signals by using linear and nonlinear transformations.
