Resumen:
Sumario:The production of large-diameter profiled pipes, such as multi-ray stars, often relies on welded blanks due to the scarcity and high cost of seamless alternatives. However, the weld seam has 5-10% lower ductility than the base metal, increasing the risk of failure during profiling. This study uses finite element modeling (FEM) to simulate the profiling process of a six-ray star-shaped pipe, aiming to identify the optimal weld seam placement that minimizes deformation intensity and maximizes structural integrity. Results identified zones of minimal deformation at the inflection points of the profile's curvature, enabling a practical strategy of pipe rotation before forming to position the seam in these areas. The study concludes that this methodology offers an effective and potentially cost-efficient solution for the industrial manufacturing of welded profiled pipes, mitigating the risk of failure.
