Experimental Study on Micro-Friction Stir Welding of Dissimilar Butt Joints Between Al 1050 and Pure Copper
نویسندگان
چکیده
The present study investigates the feasibility of producing strong and defect-free joints between 1050 aluminum pure copper sheets by micro-friction stir welding using traditional new tools. Many variables affect quality these types that parameters rotational speed, tool offset are considered main variables. Taguchi method analysis variance were used to design experiments evaluate obtained results. By analyzing results tensile test signal-to-noise analysis, average maximum ultimate strength is reported be 88 MPa, when with levels 2400 rpm, 40 mm/min, 0.25 mm. also showed speed respectively, had most significant effect on joints. minimum values from microhardness recorded for weld nugget zone heat-affected aluminum, which equal 192 HV 21 HV. Also, performing sanding operations, roughness significantly reduced. x-ray diffraction optimal samples presence intermetallic compounds CuAl2 Cu9Al4 in area. created strongly dependent formation compounds.

The ultrafine grained (UFGed) 1050 Al plates with a thickness of 2 mm, which were produced by the accumulative roll bonding technique after five cycles, were friction stir butt welded to 2 mm thick 6061-T6 Al alloy plates at a different revolutionary pitch that varied from 0.5 to 1.25 mm/rev. In the stir zone, the initial nano-sized lamellar structure of the UFGed 1050 Al alloy plate transforme...

متن کاملFriction stir welding of dissimilar alloys – a perspective
Friction stir welding does not involve bulk melting of the components that are joined. This has inspired attempts to exploit it for joining materials which differ in properties, chemical composition or structure, and where fusion can lead to detrimental reactions. The purpose of this special issue of Science and Technology of Welding and Joining was to assess the status of friction stir welding...
