This training package fully covers the various possible methods for welding simulation. First, an introduction to welding and two basic categories of welding, fusion and non-fusion welding. Next, the theories and the elements used to simulate the welding will be explained. These theories are Lagrangian, Eulerian, ALE, and SPH. After that, you will learn how to apply these theories with different methods, such as the death and birth of an element, DFLUX subroutine, etc. Next, we have discussed the simulation of two-pass gas metal arc welding Processes in Abaqus, in a manner that can be extended to multi-pass and other types of welding. This heat flux created by the electric arc is transferred to the welded parts and leads to a significant increase in temperature. To do so, we will use Goldak’s Double Ellipsoid Heat Source Model with the DFLUX subroutine (Considering the death and birth of elements). Finally, you will learn how to simulate welding with the help of six workshops: Friction Stir Welding (FSW) simulation with the Eulerian element, Explosive welding simulation, simulation of FSW with the SPH method, Butt welding with death and birth of an element method, Simulation of Arc welding between two tubes with DFLUX subroutine (Thermomechanical Analysis), and simulation of Two-Pass Arc Welding (Including the Birth and Death of Elements) and Its Extension to Other Welding Types.
