| Abstract Scope |
Medellín is the second-largest city in Colombia and the only one to have a metro system: Metro de Medellín (MdM), a mass-transport system that on average transports 811 thousand people daily. An exercise was carried out to identify components requiring spares and, a tie, part of the doors opening and closing mechanism, was selected. This component was originally manufactured from a bespoke extruded U-shaped AA6063-T83 profile with arc-welded brackets and milled-features.
FSW provides a solution for joining aluminium alloys compared to arc welding, but high investment costs for equipment remains an obstacle for its implementation in small workshops. To take advantage of FSW for small batches, a manufacturing-strategy was proposed based on the capabilities and limitations in the local metalworking sector, enabling implementation on conventional milling machines. Representative demonstrators have then been successfully manufactured for further testing. Finally, a cost comparison between the existing manufacturing route and FSW is presented. |
