Abstract: A process, for joining workpieces using hybrid mechanical connector-resistance welding. The process in some embodiments includes introducing a conductive fluid to an interface between the workpieces. The process also includes inserting at least one mechanical conductive connector into at least one of the workpieces so that the connector reaches the interface having the conductive fluid therein. The process in some embodiments includes further applying energy for welding to the at least one mechanical conductive connector so that the energy passes, through the connector, to the conductive fluid and heat is generated in the workpieces at the interface, thereby melting the workpieces and forming a weld joint connecting the workpieces.
