Global mechanical tensioning for the management of residual stresses in welds
The general principles behind the global mechanical tensioning technique for controlling weld residual stresses are examined using a finite lement model to follow their evolution throughout the welding process. While we focus specifically on friction stir welding, the tool is represented imply as a heat source. As a result, the findings have relevance to a wide range of welding processes. For a...
متن کاملResidual Stresses in Friction Stir Welding
Friction stir welding is an innovative joining process being developed for use in aerospace manufacturing. Like most welding processes there exist problems with post-weld residual stresses and subsequent geometrical distortion. The residual stress-state of a welded component can be modified using suitably applied mechanical tensioning and thus distortion can be reduced or eliminated. In the pre...
متن کاملDefect Detection and Residual Stress Measurement in Friction Stir Welds using Laser Ultrasonics
The laser-ultrasonic technique is proposed for defect detection and residual stress measurement in friction stir welds (FSW). When combined with the synthetic aperture focusing technique (F-SAFT), very good performances are achieved for detecting lack of penetration in butt joints, the detection limit coinciding with the conditions of reduced mechanical properties. Also, the detection of kissin...
متن کاملEffect of nanoparticles addition on dissimilar joining of aluminum alloys by friction stir welding
The purpose of this study was to examine the effect of adding Nano particles such as Nano Carbon Tube during Friction Stir Welding (FSW) on dissimilar Al alloy joints. More specifically, both FSW and Friction Stir Processing (FSP) were performed simultaneously to investigate the effect of adding Nano particles on mechanical properties and microstructure of the weld zone for joining AA5754-H22 a...
