The article deals with the application of chosen quality tools for visualisation of acoustic signals from corrosion process. For continuous monitoring of corrosion the acoustic emission (AE) is used. This is one of the non-destructive testing methods. Using this method it is possible to receive signals and perform basic analysis. For a thorough prediction of process conditions or degradation is necessary to combine this method with other analyzes in the field of statistics, especially quality tools. For these purposes, the control charts are used in this work. Effective prediction of corrosion status of the material is very important with regard to damages caused by corrosion worldwide. The objective of this paper is to describe the possibility of signal analysis in Minitab program, where is possible to continuously produce qualitative evaluation by means of quality tools, in this case control charts. The control chart is one of the seven basic tools of quality control. Typically control charts are used for time-series data, though they can be used for data that have logical comparability. This work demonstrates the possibility of use this quality tool for the analysis of corrosion acoustic signals.

Keywords: corrosion, acoustic emission, control charts
