Finite element simulation of laser spot welding
The present work reports on a two-dimensional axisymmetric nite element analysis of heat ow during laser spot welding, taking into account the temperature dependence of the physical properties and latent heat of transformations. An analysis based on conduction heat transfer alone, but using the ‘double ellipsoidal’ representation of the laser beam, seems to be suf cient to estimate the tra...
متن کاملSimulation of effective parameters on low-carbon steel laser welding process using finite element method
In this paper, laser beam welding of a rectangular piece of steel was simulated using Fluent software. Physical properties of analytical field was constant and its changes with temperature was ignored. In the present work, effect of tool speed and laser power on temperature distribution of workpiece surface and different deeps in the plane of symmetry and also maximum of temperature and depth o...

متن کامل3-D Finite Element Modelling of Water Jet Spot Welding
A 3-D finite element model is used to simulate water jet spot welding. The simulation is validated using the experimental data obtained by one of authors with other workers. The simulations identify parameters which correlate well with the quality of the welds produced. In particular the levels of equivalent plastic strain (PEEQ) and shear stress directions are shown to predict whether or not t...
متن کاملFinite Element Simulation of Nd:YAG laser lap welding of AISI 304 Stainless steel sheets
Laser beam welding (LBW) is one of the most important manufacturing processes used for joining of materials. It is also a remarkably complicated, nonlinear operation involving extremely high temperatures. Since its invention more than two decades ago, laser beam welding has been more of an art than a science. Laser welding of austenitic stainless steel AISI 304 the candidate material of this re...
