Influences of Tool Pin Profiles on Mechanical Properties of Friction Stir Welding Process of AA8011 Aluminum Alloy

Friction stir welding (FSW) is a grand new solid-state bonding process is an emerging surface engineering technology based on the principles of friction stir welding (FSW). Friction stir welding is well-matched joining process for non-ferrous metals in the spacious range of various manufacturing applications for joining materials without material losses to get a top priority of defectless welded joints. In this article, a thickness of 5-mm AA8011 series aluminum alloy plate was coupled by butt joint using two dissimilar tool pin shapes of the straight cylindrical probe and taper pin probe with a consistent parameter of tool revolving speed, welding speed, and downward force of 1400 rpm, 35 mm/min, and 6 kN. The tool pin shapes are the important parameter of material joining process to fix the joint properties, characteristics, quality of weld, and joint strength. The friction stir welding effects are determined after completing the joining process under a various ASTM standard testing methods, such as stiffness distribution in the entire welded zone area and material properties as compared to the base metal with testing results. The crucial tool travel feed is achieved with excellence material joints and extraordinary welded joint properties when collating to a straight cylindrical tool probe. It is identified that the taper pin profile tool offers extensive result was obtained both hardness and tensile strength for to enhance productivity, has been discussed along with the future aspects included in the area of FSW process from this experimental investigation.
