Evaluation of Energy Model Using Hypergeometry in Friction Stir Welding

Abstract:

Normal 0 false false false EN-US X-NONE X-NONE Friction-stir welding is a solid state welding. The aim of welding needs to be defect free which requires uniform distribution of weld bead. In this paper the parameters such as energy, maximum temperature and thermal conductivity involved during the Friction Stir Welding process is considered as numerical data and applied it over a Hyper Geometric Function and changes in Gamma values are studied. In Gauss hyper geometric function the thermal conductivity is taken as constant while the energy and maximum temperature developed is taken as numerical variables on the Gamma calculations. The model is applied to AA2024, AA7075 and AA6061. By Hyper Geometric investigation the uniformity of weld is found to be good for the taper tool geometry. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}
