| Abstract: | The acoustic emission technology was applied to test low carbon steel's uniform corrosion process and to obtain its acoustic emission signal;and the method which having characteristic parameters combined with wavelet packet transform was applied to analyze acoustic emission signal's characteristics of the low carbon steel corrosion process;meanwhile,basing on field test data of the storage tank,the results of comparing parameter characteristics from experiment conditions and that from actual conditions can provide the reference for the acoustic emission research of low carbon steel uniform corrosion process and the online tank acoustic emission detection. |
