Online measurement of manual welding skill

In the present study, the online measurement of the specific index reflecting the welder skill level has been experimentally studied for the purpose of human skill quantification. Three welders with different levels of skill performed the TIG (tungsten inert gas arc welding) welding task of first layer on a single V groove in flat position with different welding conditions. It is confirmed that the specific behavior of the welder with different skill level has been successfully estimated.

Representation Method for Engineering Perspective

For most Japanese Companies, knowledge succession is important for retaining technical competitiveness in the context of the rapid change of human resources. While efficient and effective knowledge succession requires the support of an IT system, the requirements for the supporting system are severe. That is, the system not only must offer the knowledge users need, but also must represent how to apprehend and utilize the knowledge.This paper introduces a method of representing technical knowledge considered in the development process of a knowledge succession support system (IVYs). It focuses on the user interface representing the standard or situation-dependent perspective of technical knowledge that experts define.
