In this work SMAW welding coupons were made on two grades of steels using dry electrodes, afterwards hydrogen (H) electrolytic charge was made to simulate aggressive conditions of H input on tensile samples that were constructed from welded joints. First of all, the objective of this work is to compare the mechanical response of these samples with and without H electrolytic charge, and the second one is to evaluate by means of a specific metallographic technique application, where H was occluded.
