This paper deals with "Joint Design Supporting System" that aims to support activities of welding design and joint design comprehensively. The following concepts are introduced into our system in order to deal with both the welding design and joint design explicitly:
(1) Design information on both joint and welding is clearly and explicitly defined as product data.
(2) The phase of joint design is different from the phase of welding design, and these two phases start from the division of the full structure into parts and end in determining values of detailed data to execute welding operations.
(3) Joint and welding data is decomposed into some data, and appropriate design procedures depend on the decomposed data.
(4) "Determining optimal joint data" is converted into "selecting the optimal plan from a lot of feasible design plans". That is to say, a lot of feasible plans in every design stages are created semi-automatically and evaluations of each plan are calculated automatically by our system. As a result, optimal design plans are selected and the design stage moves to the next.
(5) The design processes that are explicitly described are utilized in our system.
In order to implement our system, two design process models of both welding and joint are discussed in this report: one model is "Vertical Flow Model" and the other is "Horizontal Flow Model". The "Vertical Flow Model" indicates the design process among design stages, on the other hand, the "Horizontal Flow Model" indicates the value determination activities in each design stage.
Some examples of both welding design and joint design by using our system are shown in this paper.
