Abstract—Presented article is focused on mathematical simulation of forming process of weld elbows for the purpose of production process improvement. Necessity of simulation and subsequent experimental verification of results is based on problems during the manufacturing process of weld elbows. Simulations were made using Deform 3D and final shapes of arcs were subsequently analyzed. Simulation in software is realized using finite elements method. The simulations were held under ideal conditions and with ideal shape of spike end tool. Models of semi products were based on requirements from the industry. Subsequently will be performed experimental verification of obtained data by manufacturing of test samples using unimproved tool. Goal of analyses is to achieve shape of the spike end tool with no further necessity of adjustment for obtaining correct final product.
