USE OF STATISTICAL QUALITY CONTROL METHODS IN MANUFACTURING BRIDGE METAL STRUCTURES
(pp. 30-37)

Abstract. This article describes the use of statistical methods of quality control and management in the manufacturing metal bridge structures, such as: –  cause and effect diagram (Ishikawa diagram). Causal factors affecting the quality of welded joints were established; –  checklist. The form of the control sheet for registration of types of surface defects of butt welded joints were developed; –  pareto Chart. The most common types of surface defects of butt welded joints were identified; the types of surface defects of butt welded joints, leading to the greatest losses were determined. ABC method – analysis of Pareto diagram of internal defects of welded joints. General conclusions on the results of their application were made.

Keywords: quality, statistical methods of monitoring and managing product quality, cause and effect diagram (Ishikawa diagram), checklist, Pareto chart, ABC method analysis of the Pareto diagram.
