TL;DR: In this article, the authors developed a nonlinear finite element method for predicting the weld-induced deflection and residual stress of semi-industrial scale stiffened panel, using a novel heat source model consisting of a Goldak's double-ellipsoid mathematical model representing the arc source, combined with a truncated cone Gaussian mathematical model to simulate the laser source.

TL;DR: In this article, the most representative investigation regarding the use of this technology to join large thickness flat panels of naval steel is presented. And the industrial need of performing one single pass procedure to assure high quality welds of high thickness is suggested as one of the key aspects for future investigations.

TL;DR: In this paper, a combination of the laser beam power, pulse duration and spot diameter is used to obtain high quality joints of steel thin plates, and the tensile test performed at samples extracted from double sided laser welds showed good resistance results, fracturing at the base material of joints.

TL;DR: In this article, a novel approach based on the application of LBW under conduction regime (with a High-Power Diode Laser, HPDL), has been employed for the first time to weld this alloy.

TL;DR: In this article, a Finite Element Method (FEM) has been developed to simulate the laser beam welding of Ti6Al4V alloy under conduction regime and the Goldak double ellipsoid model has been taken for the first time to simulate this LBW conduction process.
