Numerical study on stress induced cambering distortion and its mitigation in welded titanium alloy sheet

Abstract: Arc welding process is widely used for fabricated thin structures in aerospace, shipyard, etc. Welding deformation is undesirable owing to the decrease in buckling strength and injures the beautiful appearance of structures. In addition, it causes errors during the assembly which result in more rework and productivity restriction. Welding deformation is complicated in real structure and is difficult to control. In the present study, numerical simulation by applying finite element has been performed using ANSYS… Show more

“…The earliest experiments were carried out in the 1960s in support of NASA's Saturn programme [105]. Although several cooling arrangements have been suggested, most modern experimenters have used an intense heat sink trailing the welding heat source to create a characteristic valley-shaped temperature distribution 7 [106,107,108,109,110], shown in Figure 9. An example of a cooling device designed to achieve this is shown in Figure 10.…”

“…Recent simulations using commercial software such as ABAQUS [8,9], ANSYS [10], and the more function-specific SYSWELD [11,12] have all been successful in determining residual stresses, both for LBW and other welding processes.…”

“…Due to significant increases in computational power and developments in computational welding mechanics, commercial software such as ABAQUS, ANSYS, and SYSWELD have been used by many researchers to determine distortion patterns and residual stresses for various welding processes [15][16][17][18][19][20]. In the above-mentioned FE packages, SYSWELD is specially designed to perform welding simulations where heat source geometry definitions, moving heat source functions, heat and thermochemical treatment modelling, and phase transformation modelling are inbuilt.…”
