Abstract

Currently, quality control in modern enterprises is one of the factors creating the principles of organization and functioning of enterprises. The paper presents one of the techniques of non-destructive testing - ultrasonic testing in quality control of casting of the base of an industrial robot. Ultrasonic testing is used for inspection due to the possibility of detecting internal, surface and sub-surface discontinuities in the entire volume of the tested material. The aim of the study was to determine, using traditional quality management tools (Pareto-Lorenza and Ishikawa diagrams), the most significant incompatibilities of castings detected in ultrasonic testing and to reduce or eliminate the number of non-compliant products. The survey concerned a batch of products manufactured in the 3rd quarter of 2018 in one of the companies in the southern part of Poland. The results of the ultrasound examination revealed the presence of discontinuities (emptiness) in the casting. Tests carried out using the Pareto-Lorenz diagram have shown the most important discontinuity in the products - material voids. The use of the presented tools may allow for precise reaching the source of quality problems in the casting process. Further research directions will be related to the application of the presented research methodology in the quality control of the remaining products offered by the enterprise, and then its implications in enterprises of similar specificity.
