<p>The aim of this study was to evaluate different weld coatings of Ni alloy applied by the process of submerged arc welding (SAW) on API 5L Gr B steel used in the Oil and Gas Sector. The weldings were made with an AWS ERNiCrMo-4 filler metal of 1,14mm-diameter and an agglomerated, basic fluoride and non-alloying flux. Three weld coatings were made, two of them with pulsed and one with conventional current. Then, these weld coatings were characterized according to microhardness, optical microscopy, Energy-dispersive X-ray spectroscopy (EDX) and corrosion resistance tests. The results showed that the coating applied with conventional current presented lower dilution levels, higher width and height, and higher corrosion resistance when compared to the coatings applied with pulsed current</p>
