Summary: | Welding plays an important role in the component joining process. This study aimed to
determine the effect of shielded metal arc welding on the microstructure, hardness, and tensile
strength of nodular cast iron. Shielded metal arc welding was performed using AWS A5.15 Eni-CL
electrodes. Scanning Electron Microscope is used for metallographic observation. Hardness testing
was carried out on base metal, heat-affected zone, and weld metal. This hardness test uses the Vickers
technique. Tensile testing was carried out to determine the effect of welding on tensile strength. The
results of the metallographic investigation showed the disappearance of the ferrite phase and the
appearance of the ledeburite phase in the heat-affected zone and weld metal. The area with the highest
hardness occurs in the heat-affected zone while the lowest hardness occurs in the weld metal. There
is a decrease in the tensile strength of nodular cast iron due to the welding process |
