An integrated design and planning environment for welding

Part 8: Knowledge Creation and ManagementInternational audienceThis paper addresses the automated assessment of manufacturability of air-craft engine components in the early stages of design, focused on the welding process. It is a novel part of a multi-objective decision support tool for design evaluation, currently running at a manufacturer of jet engine components. The paper briefly describes the tool and how it impacts the product development process. Further, the paper presents an integrated method for manufacturability assessment by finding welding processes that complies with all geometrical and other constraints found in the CAD-models of the conceptual engine. Here, preferences made by manufacturing engineers serves as a base for a manufacturability index so that different parameter settings in the CAD-models can be compared to find the best parameter settings, considering the trade-off with other performance criteria’s of the engine

“…In this stage, much computer-aided software includes CAD (Computer Aided Design)/CAE (Computer Aided Engineering) /CAM (Computer Aided Manufacturing) programs are developed [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45]. Usage scope of these programs is expanded to entire industries because these programs break the limitation of functionality and become more and more universal.…”

Abstract-As one solution to complex product design, the integrated design environment has experienced several decades of development with great changes. This paper reviews the emergence, development history and future trend of integrated design environment. Firstly, the concept and connotation of design are analyzed, and then from the development of design behavior and the development of computer aided design, the inevitability and development history of integrated design environment are elaborated. Secondly, the background and characteristic of different kinds of integrated design environment were analyzed and elaborated. Finally, based on the trend analysis of the integrated design environment, future research direction and goals are proposed. Through this review, basic materials and direction for the related academic research can be provided.

“…Related to production costs, the most important decisions regarding costs and quality demands are usually made during the design stage [47]. The design phase includes the specifications of the weld structure, like the component shapes, positions of joints and also joining methods, but the whole welding network, including suppliers' own collaboration partners, has an effect on product costs by their actions in production.…”

Abstract:The objective of this study is to examine the manufacturing and conformity of welded products and the significance of co-operation of different functions to welding quality. This study focuses on costs arising from nonconformity from the manufacturing perspective. It briefly discusses unnecessary costs, claim costs and warranty costs in the production chain. It furthermore takes an overview of challenges in welding manufacturing in the engineering field with empirical research in the industry and shows that failures and defects are identifiable and known in companies but very rarely the root cause of imperfections is investigated. The requirements from manufacturing go unrecognized at the many levels of organisation. One of the main obstacles to improving welding functions is the lack of co-operation and knowledge of the demands on welding. This can cause continuous nonconformity in products and in welding manufacturing. The observations have been collected from welding networks in engineering workshops where GMAW welding is a commonly used process. The results provide a framework for future research to define the importance of actions of different functions to the quality and costs of manufacturing.
