Abstract
In this study, the microstructure and strength properties of friction stir welded 6061-T6 aluminum alloy to ultra-low carbon steel have been investigated using different advancing speeds of 100, 200, and 400 mm·min−1 at constant rotation rate. Microstructure observations have been conducted by optical and scanning electron microscopy. The joint strength was evaluated on a tensile testing machine. The effect of advancing speed on the shear load of a joint has been found, as well as a relationship between microstructures and mechanical properties.

Summary
Friction stir welding (FSW) is potentially a practicable joining process for dissimilar materials It is a solid state process where a non-consumable rotating tool with a specially designed pin and shoulder is inserted into the abutting edges of sheets or plates to be joined and subsequently traversed along the joint line [1]. Ozdemir et al [8] investigated the effect of rotational speed on the interface properties of friction-welded AISI 304L and steel They found a correlation between the tensile strength of the joint and joining rotational speed. The objective of this work is to focus on the effect of traverse speed on the mechanical properties and microstructural characteristics of the welded FSW 6061 aluminum alloy to ultra low carbon steel with a lap joint configuration. The tool used is made from X40CrMoV51 steel, which is an economical tool steel
