The Differences in SMAW Welding Toughness Using V Seams on SS400 Steel with Notch Variations

This study aims to determine the difference in the magnitude of the impact toughness values of SMAW welding with V seams on SS400 steel with various notches. The results showed that the highest impact value was obtained from the U seam specimen with a value of 2.53 joules/mm2 , and the lowest impact value was obtained from the V seam specimen with a value of 1.43 joules/mm2 . The average value of the SS400 steel specimen is 1.96 joules/mm2 . The significance value of the data that has been processed in SPSS is 0.255. This data has a value greater than 0.05. SS400 steel has a toughness value of 1.96 joules/mm2 and has no significant difference between the notch shapes.
