This book investigates the effect of tool pin profile on the mechanical properties of aluminum alloys AA2024-T351 joints produced by friction stir welding. Four different tool pin profiles were developed, there are straight cylindrical, step cylindrical, straight triple-sided prism, and straight square block which were used to weld the joints. All the welds were produced perpendicularly to the rolling direction for aluminum alloys. Tensile and bending tests were performed to evaluate the mechanical properties by using computerized universal testing machine. Among the four tools, straight squar...
This book investigates the effect of tool pin profile on the mechanical properties of aluminum alloys AA2024-T351 joints produced by friction stir welding. Four different tool pin profiles were developed, there are straight cylindrical, step cylindrical, straight triple-sided prism, and straight square block which were used to weld the joints. All the welds were produced perpendicularly to the rolling direction for aluminum alloys. Tensile and bending tests were performed to evaluate the mechanical properties by using computerized universal testing machine. Among the four tools, straight square block pin profile gives better mechanical properties. Statistical analysis was applied for obtaining mathematical models that relate the mechanical responses; elongation, tensile strength, and maximum bending force, with the input parameters; welding speed and rotational speed, to verify the adequacy of these models.
