Process Analysis During Edge Preparation for Steel Plate Between Expert and Non-expert

As joining by welding is a particularly important processing method for melting and integrating multiple components. That is because poor welding is directly linked to fatal vulnerability in the product structure. Therefore, high-quality welding technology is required, which means the accuracy of the previous step called "edge preparation" is also important to achieve high-quality welding. "Edge preparation" refers to a step of opening up the edges of the object to be welded in a suitable form in order to facilitate welding. Edge preparation, unlike conventional fusing processing, requires delicate and advanced technologies for cutting a steel plate obliquely. In this study, as one of the methods of explicating the tacit knowledge in manufacturing, that is, the inheritance of technology in edge preparation, the work of expert and non-expert was comparatively observed in order to clarify differences.
