A smart acoustic information recognition-based welded weld impact quality determination method and system, comprising: controlling a tip of an ultrasonic impact gun () to perform impact treatment on a welded weld with different treatment pressures, treatment speeds, treatment angles and impact frequencies, obtaining acoustic signals during the impact treatment, calculating feature values of the acoustic signals, and constructing an acoustic signal sample set including various stress conditions; marking the acoustic signal sample set according to impact treatment quality assessment results for the welded weld; establishing a multi-weight neural network model, and using the marked acoustic signal sample set to train the multi-weight neural network model; obtaining feature values of welded weld impact treatment acoustic signals to be determined, inputting the feature values into the trained multi-weight neural network model, and outputting determination results for welded weld impact treatment quality to be determined. 1. A smart acoustic information recognition-based welded weld impact quality determination method , which is characterized in that: comprising the following steps:{'b': '1', 'S) controlling a tip of an ultrasonic impact gun to perform impact treatment on the postwelding seam with different treatment pressures, treatment speeds, treatment angles and impact frequencies, acquiring acoustic signals in the impact treatment process, calculating feature values of the acoustic signals, and constructing an acoustic signal sample set including various treatment conditions;'}{'b': '2', 'S) determining the impact treatment quality of the postwelding seam, and marking the acoustic signal sample set according to a determination result, In the determination process, a resistance strain-gage is used as a sensitive element for measurement, and an indentation is made at a center of a strain rosette by impact loading; the strain-gage records the change of strain increment ...
