Welded Joints’ Incompatibilities Analysis in Production of Semi-trailers Car

Abstract

This paper analyzes causes and effects of formation of incompatibilities in the welding process of structure elements of car semi-trailers. There were identified most frequently occurring incompatibilities in this process, and was set out for them RPN. Based on conducted research there was proposed implementation of corrective and preventive actions in identified critical areas. There was carried out recalculation of RPN value after the implementation of corrective actions. This paper presents the importance of visual control elements in the process of monitoring the output elements from the welding process of construction. As the most important element of corrective actions was considered the process of continuous employee training and implementation of seven principles of the Toyota Management (apply visual control to ensure that no problem is in hiding).
