Abstract

Abstract

Cyclic immersion corrosion tests simulating industrial atmospheric environments and monotonic tensile tests were conducted on weathering steel welded joints after rust layer stabilization treatment to investigate the influence of rust layer stabilization on the corrosion resistance and mechanical properties of the joints. The results indicated that the stabilization treatment enhanced the compactness of the inner rust layer， effectively suppressed long-term mechanical performance degradation， and provided excellent long-term anti-corrosion effects. Under monotonic tensile loading， all welded joint specimens fractured in the base metal region at a distance of 5-20 mm from the weld， exhibiting significant plastic deformation.
