Abstract

Abstract: Welding modularization can make the process planning and manufacturing of complex welding products easier, convenient and synergy. The appropriate units partition is critical for welding modularization. This paper proposes a method of welding units partition for complex welding parts. Firstly, the basic parts and sub parts of welding units are defined. Then, the basic parts are evaluated by using the fuzzy analytical hierarchy process (FAHP) method and the number of basic parts is determined by the improved units partition formula. Furthermore, the welding units are classified by the minimum spanning tree (MST) algorithm and the interference matrix is used to evaluate partition results. Finally, a rear sub frame of automobile is taken as an example to validate this method.
