In this study, the tensile strength characteristics of welded joints with and without corrosion are experimentally investigated by accelerated corrosion testing of specimens butt-welded with dissimilar materials of stainless steel and carbon steel. First, tensile tests were conducted on the nonexistence or existence of corrosion using butt-welded specimens of stainless steel and carbon steel of equivalent design material strength. The experimental results show that the tensile strength properties of butt-welded specimens of stainless steel and carbon steel are affected by corrosion on the carbon steel side, and that the stress concentration associated with cross-sectional defects is larger than that of specimens without corrosion damage.
