Abstract

The welding process of AISI 1020 steel causes changes in microstructure and corrosion resistance. The corrosion attack pattern occurring on the steel can be evaluated by observing the corroded surface. This research aims to determine the corrosion attack pattern on welded joints of AISI 1020 steel. Specimens of AISI 1020 steel that have been welded and subjected to post-weld heat treatment (PWHT). PWHT involves heating the specimens to temperatures of 400, 500, and 600°C with a holding time of 1 hour, followed by air cooling. The specimens, both before and after PWHT, were tested for corrosion using polarization techniques. The surface of the specimens after corrosion testing was observed using a microscope. The observation results indicate the presence of pitting corrosion on the specimen surfaces after the corrosion test.
