Abstract
Concentric tubes are used in heat exchangers, chemical and bioreactors, air conditioners, etc. for transmitting fluid from one location to another. Butt joining of tubes is generally performed and this is accomplished by welding and mechanical fastening. The joining of concentric tubes is mostly performed by fusion welding processes. In the present work, an alternative approach to join two concentric tubes using end forming is proposed. A die groove is designed using finite element (FE) analyses to optimize the process parameters for successful joining. FE code ABAQUS/CAE is used for the FE simulations. The tubes are joined by end forming within the die groove. Such FE simulations helped in practical demonstration of the joining process as well.
