A Framework for a Reconfigurable Welding Jig for Sheet Metal Panel Component of a Railcar

Reconfiguration is an effective way of restructuring the components of a system to ensure efficiency, modularity, scalability and flexibility. The aim of this work is to reconfigure a welding jig for assembly operation for a railcar in order to provide effective mix of flexibility and dedication. A framework for the reconfiguration of a welding jig was proposed in this study, which takes into consideration some design considerations in order to tackle some challenges identified in the existing jigs. The implementation of the proposed design framework will minimize the challenges identified and the resultant effect will bring about good dimensional accuracy and surface finish of the work piece. It will also bring about increase in welding time with reduction in the efficiency of welding. The reconfigurable welding jig design framework proposed in this study unveils the best possible way for clamping, location and rearrangement of the jigs component and its accessories for optimum performance and safety. This work finds application in the manufacturing industries in their quest for the development of efficient work holding systems in order to increase the production rate.
