Corrosion Effect on Car Welded Jointed in Terms of Sea Environment Effect

Abstract:

Almost 50% above parts in the car are weld jointed. Corrosion effects are main threats to all this welded part and commonly cause the mechanical failure. Corrosion effect can be more when the car or any transportation is exposed to sea environment or salt water. The objective of this study are determining the effect of corrosion and predict the degree of durability on welded joint under corrosion effect. In order to perform the corrosion, salt spray test are used to give the corrosion effect welded joint parts. 48 hours in Salt spray test can give corrosion effect equal to 5 years of industrial condition. To obtain the structural condition, the tensile test, Infinite Focus Microscope (IFM) and Metallographic test was performed to get the corrosion rate. From the experiments, it was found that the corrosion effects will increase by the times. The roughness of the surface corrosion on welded joint gives a lower durability due to failure in welded parts.
