The realtime and online quality monitoring purpose could be realized. Effectiveness of the developed model was validated through data training, testing, and validation. The electrode force, welding current, welding time, and first five principal components were designed as network inputs. A back propagation neural network model was then proposed to simultaneously predict the nugget size and failure load. The first principal component was selected as independent variable in regression analysis for quality estimation. Principal component analysis was made on discrete dynamic resistance values. Electrode force effect on dynamic resistance and failure load was much smaller than that of welding current. ![]() The bulk material heating stage could not be detected under very high welding current condition. A smaller electrode force or lower welding current was found to promote the initial resistance peak. Typical dynamic resistance curves were divided into several stages based on the weld nugget formation process. The present study aims at solving weld quality monitoring problem in small scale resistance spot welding of titanium alloy.
