Comparative study on penetration and eddy current testing for welding defects in aluminum alloy

In the examination of surface defects in newly manufactured aluminum alloys, Penetration Testing and Eddy Current Testing were employed to identify flaws in the welding process. The causes of defects in the welding of these newly manufactured aluminum alloys were highlighted, and the reasons for not using other non-destructive testing methods were also explained. Finally, a practical comparison of the test outcomes from both methods revealed their effectiveness in accurately detecting defects in practice, and ensuring the omissions of overlooked weld imperfections.
