Welded stainless steel tubes have several critical points during plastic deformation processes, so the effects of different process parameters and geometric characteristics on various stainless steel families were studied during the finite element method (FEM) simulations. The analysis of the simulation outputs, such as stress, strain and thickness, was performed through mappings in order to evaluate their variation and distribution caused by the parameters, and the feasibility of the simulated process was evaluated through the use of Forming Limit Diagrams (FLD). The experimental validation of the model was also performed by comparing real cases. The main parameters that mainly guide the outcome of the simulations have been highlighted and critical points have been identified that require additional elements not present in the model, whose absence could lead to a deviation of the result from reality.
