New Design of Aluminum 6061 Welding Joining Using Friction Stir Welding Method

Abstract

Parallel, lap, corner, and T joints are commonly used in fusion welding and solid welding. Other joints made are lap and butt joint. This study aims to evaluate a new design of fitting model single U and double U for friction stirr welding of Aluminum. Aluminum sheet 6061with a thickness of 10 mm, will be cut to a length of 150 mm and a width of 100 mm, then a locking groove will be made with an inner size of 5 mm and a length of 150 mm The flow is used to be paired in the FSW process. This experiment results show the high tensile strength that occurs in the double joint u, is 13.4 kN while the average is 12 kN. Single connection experiment u the highest tensile strength is 12.89 kN, while the average value is 10.37 kN. The hardness is higher in double u joints compared to single u joints.

“…The joint design has good tensile strength and will provide information about the newly designed joints in the FSW welding method. The nugget, TMAZ, and HAZ only function as locks, while their shear strength lies in the joint design, as also reported by other [15]. The shape of the indenter pin visually changes the spiral form of the welded surface, and the fracture is located in the stir zone.…”

“…The hardening of the material is affected by rotary friction, axial pressure, and becomes a force with the friction pressure and forging pressure that occurs during welding [37]. These forces cause increased friction and ultimately increase the hardness and Young's modulus of each zone on the steel side [38], but the hardness was decreased caused by high heat energy on the joining interface will have oxide trapped in the nugget and finally reduce the mechanical properties, especially hardness [39].…”
