Analysis of the Possibility of Used of the Quality Management Techniques with Non-Destructive Testing

The quality of products is, in particular, analyzed in product case from the aerospace industry in order to achieve the desired quality and safety levels.The aim of the study is to propose the use of selected quality management techniques in the quality control process made by non-destructive testing.The subject of the research were two products made of steel 410, in which incompatibilities were detected relatively frequently.It was a four-hole flange bearing housing and a gasodynamic sealant.The products mentioned were subjected (according to the quality procedure) to non-destructive testing with two methods: a fluorescent and a magnetic-powder.In order to identify the source cause of incompatibilities the implementation of selected quality management techniques was proposed.These techniques were: 5W2H method, Ishikawa method and 5Why method.Although these methods are simple, they were not used in the enterprise so far.So it was an order to use them, to check their adequacy.By supplementing the non-destructive research with the proposed sequence of selected quality management techniques, it was shown that it is possible to identify the source cause.In addition, by indicating the source cause it is possible to propose improvement actions adequate to the problem.So it will improve the quality of the next products.The proposed solution using the 5W2H method, Ishikawa diagram and 5Why method is complete and easy in practice technique for qualitative analysis to identify the root cause of incompatibility.After using these not complicated methods, it will be effective to use in the appropriate sequence more advanced methods, such as 8D, Six Sigma and DMAIC.
