It is exposed to atmospheric conditions during the manufacture of ships before launching. Exposed atmospheric conditions cause corrosion of the steels used in shipbuilding. In this study, it is aimed to reveal the change in the pre-corrosion and post-corrosion mechanical properties of the Grade A ship sheet metal during the process of smelting. For this purpose, Grade-A ship plates are combined with arc, arc and submerged arc arc welding methods. Some of these sheets were then subjected to neutral salt spraying. Changes in the hardness, tensile strength and bending strengths of the sheets not subjected to neutral salt spraying process were determined. In the study, it was seen that a lower rate of red rust occurred in the sheets joined with the gas-welded welding process and a lower rate of post-corrosion tensile strength and bending strengths decreased.
