Abstract

The microconstituents in a butt welded ASTM A 36 steel with edge preparation by means of electric arc welding with electrode E 7018 were quantified through digital image processing. Samples with bevels of 30 and 35o were prepared, which were called MI for the former and MII for the latter. The phases, the grain boundaries and the area present in the microstructure of this steel visualized in an element called pixel were identified. It was determined that, in the molten zone and in the zone affected by heat for the 30o bevel, the phase that predominates is pearlitic with 82.25%, which occupies the greatest distribution over the area of the matrix and in that of 35th, there is a tendency to remain the same, but with 56.82%; which is associated with the heat input due to the effect of the thermal cycle and the type of angle used.
