Procedimiento y caracterización de soldadura en materiales con alto contenido de carbono equivalente (Ceq mayor 0.4%)

Abstract

This work addresses the Procedure and Characterization of welding in materials with high carbon equivalent content (Ceq greater than 0.4%), using the FCAW welding process. The work is carried out from the structural and metallurgical point of view. For the experimental stage, parameters such as current intensity and consideration of preheating are considered, these measures are considered to obtain a good weld bead, the verification of the best parameters is carried out with non-destructive tests, stories such as: visual inspection on each plate, penetrating inks and x-rays, destructive tests are also performed: metallographic analysis, hardness, tensile tests, flexion of the face and the root. In the anti-abrasive steels, the manufacturers considered the preheating with the chemical composition and the thickness of the plate, this work found a relationship according to the degree of hardness. The best welding conditions are with preheating, due to the high hardness of the steel used in this job
