Abstract

In recent years,corrosion of low carbon steel has become an important issue in safety,especially in the welded part of a structure.Additionally,corrosion can easily take place on any metal structures unpredictably and might cause catastrophic failures as long as the environment is appropriate,particularly when there is a continuous presence of moisture and oxygen.In this study, the experiment is aimed to investigate the corrosion product,surface hardness,weight loss and rate of corrosion of low carbon steel welded plate in 3.5% of sodium chloride solution.Hence,corrosion immersion test and Rockwell hardness test along with various characterization techniques such as Optical Microscope (OM),Confocal Microscope (CM),Scanning Electron Microscopy (SEM) and Electron Dispersive Spectroscopy (EDS) has been conducted in order to achieve the objectives.The data gained for welded specimens will be compared with non-welded specimens as its bench mark.It is found that the hardness,weight loss and corrosion rate of welded specimens is worse than non-welded specimens. This study is important in order to provide a quantitative understanding and explanation on corrosion attack of welded low carbon steel.
