Análisis de la influencia del cobre en la soldabilidad de aceros de bajo carbono

Abstract

In the present work the influence of copper on the weldability of low carbon steels was analyzed, the percentage of copper in the weld bead of the steel with which the problem of cracking starts and the effect that existed in the mechanical properties. Fissure detection was done using the non-destructive testing techniques most commonly used at industrial level. The percentage of copper in the steel with which the cracking problem began was 3.02%. A diminution in tensile strength was evident in the specimens, compared with the tensile strength of the base material, creating a tendency to decrease the tensile strength as the copper content increases. In general, the copper in the steel does not present a good mixture, forming a two-phase system.
