• The constant temperature liquid circulating system designed is reliable. • Synthetic seawater would severely reduce the fatigue life of the specimens. • Fatigue damage evolution can be described by strains versus fatigue cycles. In this study, a constant temperature liquid circulating (CTLC) system was designed and implemented to control the ion concentration, temperature, and pH value of a corrosive solution during the whole process of corrosion fatigue tests. A set of T-welded-joint specimens were manufactured from Q345qD steel and subjected to corrosion fatigue and fatigue tests. The experimental results show that the corrosive environment greatly reduces the fatigue life of the specimens. The mean reduction in the specimen lifetime is up to 47.7%. These tests also prove that the CTLC system designed in this study and described herein is both reliable and applicable. [ABSTRACT FROM AUTHOR]
