Knowledge management on weld joint object in engineering design support

Consideration on product design is remarkably increasing in manufacturing design and how to improve the intelligent productivity in engineering design business has become a pressing need for enterprises. Especially in the field of welding vessel design, it is not only to concern with the geometric information like drawing in design, more important thing to be considered for a designer is to treat with the engineering design knowledge. But the general-purposed CAD systems do not treat it efficiently. Thus, there has been a considerable growth of interest in knowledge-based design support systems for engineering design. We have proposed an assembly structure model for welding design object. This paper focus the discussion on modeling and representation of weld joint, and the management of the public design knowledge based on the proposed model.
