Experiments and Numerical Simulations on Laser Welding Deformation of Thin Plate Considering Constraint Clamp

Abstract:

As to laser welding process of thin plate, the configuration style of welding deformation under constraint condition is investigated by designing two cases: (1) the free bead welding, (2) the bead welding with a constraint clamp. Both experiment and simulation for these two cases are carried out to study the corresponding phenomena of welding deformation. In numerical simulation, an equivalent method, i.e., the Local Equivalent Welding Element (LEWE), is used to predict the residual deformation of welding plate, which possesses higher efficiency and accuracy. Research results show that the constraint condition will remarkably affect the residual deformation behavior of welded plate.
