Abstract: Chemical composition analysis,metallographic examination and corrosion test were conducted to investigate the seawater corrosion behavior of base metal zone(BMZ),heat-affected zone(HAZ) and weld zone(WZ) of the stainless steel pipe welds.The law of seawater corrosion around the welds was drawn and the effects of the microstructure on the seawater corrosion behavior of the welds were revealed.
