Tensile properties and fracture locations of friction-stir-welded joints of 2017-T351 aluminum alloy
Friction stir welding (FSW) is a new and promising welding process that can produce low-cost and high-quality joints of heat-treatable aluminum alloys because it does not need consumable filler materials and can eliminate some welding defects such as crack and porosity. In order to demonstrate the friction stir weldability of the 2017-T351 aluminum alloy and determine optimum welding parameters...
متن کاملSeam-Tracking for Friction Stir Welded Lap Joints
This article presents a method for automatic seam-tracking in friction stir welding (FSW) of lap joints. In this method, tracking is accomplished by weaving the FSW tool back-and-forth perpendicular to the direction of travel during welding and monitoring force and torque signals. Research demonstrates the ability of this method to automatically track weld seam positions. Additionally, tensile ...
متن کاملevaluation of fatigue life of friction stir welded 7075-t651 aluminum alloy joints
abstract – aluminium 7075- t651 alloys are widely used in the production of light weight structures requiring a high strength to weight ratio and high corrosion resistance. the effect of processing parameters on fatigue life of 7075- t651 aluminium joints produced by friction stir welding was investigated in the present study. welding samples were made by employing rotating tool speed of 770, 9...
متن کاملEffect of Welding Speed on Defect Features and Mechanical Performance of Friction Stir Lap Welded 7B04 Aluminum Alloy
Friction stir lap welding of 7B04 aluminum alloy was conducted in the present paper, and the effect of welding speed on the defect features and mechanical performance of lap joints was investigated. The results indicate that the hook defect at the advancing side (AS) can reduce the effective thickness of the top sheet, and the sheet thinning level is gradually lowered by increasing the welding ...
متن کاملEvaluation of microstructure and mechanical properties of friction stir welded copper / 316L stainless steel dissimilar metals
In the present research, friction stir welding (FSW) process was used for butt joining of pure copper plate to 316L stainless steel plate. Mechanical properties and microstructural characteristics of the joint were evaluated by microhardness and tensile tests as well as optical and scanning electron microscope (SEM). It was found that microstructure of the weld nugget (WN) has fine grains where...
