    The diffusion bonding is one of the methods used to join dissimilar metals. Specimens of duplex stainless steel and low carbon steel were joined by diffusion bonding under varied temperature and holding time. The specimens were clamped using jigs and heated in a furnace. Tensile test was performed on the joined samples. The effect of bonding time and holding temperature on tensile strength and quality of the diffusion bonds were observed. Tensile strength of the joints was examined and the highest tensile strength of 116.12 MPa are obtained at temperatures of 900 °C and holding time of 180 min.

    Friction stir welding (FSW) is a recent technique that exploits a non-consumable rotating welding tool to generate frictional heat and plastic deformation at the welding location. The principal advantages of FSW, being a solid-state process, are low distortion, absence of melt-related defects and high joint strength, even in those alloys that are considered non-weldable by conventional techniques. Hard materials such as steel and other important engineering alloys can now be welded efficiently using this process. The understanding has been useful in reducing defects and improving uniformity of weld properties and expanding the applicability of FSW to new engineering alloys. This project focuses mainly on the experimental study of FSW on AA5083 T-joint in 1F position. This study investigates the jig fixture and tool pin design with effects of pin rotation speed on the macrostructure of the joint. The present work deals with an experimental campaign aiming on FSW on aluminium alloy 5083 T-joint. Tool pins are fabricated using material high tensile steel H13 with angle shoulder with heat treatment process for surface-hardened tools.
