Title: Process Model and Design for Magnetic Pulse Welding by Tube Expansion
Language (ISO): en
Abstract: In this paper a design methodology for magnetic pulse welding processes is presented. To examine fundamental correlations of part- and process-parameters, a model experiment is used. Different impacting conditions are tested and the effect on the joint quality is evaluated by metallographic analysis. Conclusions regarding suitable impacting parameters are drawn. Electromagnetic expansion tests are carried out in parallel with the aim of adjusting the impacting parameters via typical process parameters. Therefore, the forming velocity is measured online and the impacting angle is varied via the geometry of the joining zone. To verify that the tendencies observed in the model experiment occur also in magnetic pulse welding, the influence of the impacting parameters on the joint quality is investigated for magnetic pulse welded tubes, too. Finally, the results of both investigation paths are combined and serve as a basis for target-oriented design of magnetic pulse forming processes.
