| dc.description | Leakproof tube-to-tubesheet welds (TTW) are essential for avoiding mixing shell-and-tube heat exchanger fluids. [1] Currently, tube-to-tubesheet joints are fabricated using tube expansion, seal and strength welding. [2] The tungsten inert gas (TIG) welding process is mainly used to manufacture welded or expanded-welded tube-to-tubesheet joints . | |
| dc.description.abstract | This In expanded-welded tube-to-tubesheet joints, where welds separate the two transfer fluids, tungsten inert gas (TIG), welding is preferred traditionally. A non-conventional novel technique for sealing the roller-expanded joints using friction stir welding (FSW) instead of TIG welding is proposed. FSW was effective with up to 8% expanded tube-to-tubesheet joints. The minimum leak path of 4%, 8%, and 12% expanded and welded joints were 0.74mm,1.34mm and 0.32mm, respectively. Grains were refined at the stir zone due to dynamic recrystallization and at the expanded zone due to compressive stress imparted by rollers. The results proved that the FSW is a promising technique for producing quality sealed joints. Keywords: Aluminium, Friction stir welding, Heat exchanger, Tube, Tubesheet. | |
