EFEK VARIASI ELEKTRODA TERHADAP SIFAT MEKANIK PADA SAMBUNGAN BAJA A36 DAN SS304 DENGAN METODE SMAW

---

Dissimilar welding between ASTM A36 carbon steel and AISI 304 stainless steel is widely applied in manufacturing industries because it combines the mechanical properties of carbon steel with the corrosion resistance of stainless steel. However, differences in chemical composition and thermal properties may affect the quality of the welded joint. This study aims to investigate the effect of E308L, E309L, and E316L electrode variations on the mechanical properties and microstructure of ASTM A36–AISI 304 dissimilar welded joints using the Shielded Metal Arc Welding (SMAW) process at a welding current of 100 A. The tests conducted included Charpy impact testing, Vickers hardness testing, and microstructural observations in the base metal (BM), heat affected zone (HAZ), and weld metal (WM) regions. The results showed that the E316L electrode produced the highest impact energy of 17.402 J, followed by E308L and E309L with values of 13.724 J and 13.171 J, respectively. The highest hardness value was also obtained using the E316L electrode, reaching 192.87 HV, while E309L and E308L produced maximum hardness values of 179.52 HV and 175.07 HV, respectively. Microstructural observations revealed that the weld metal region was predominantly composed of austenite and δ-ferrite phases, while the HAZ experienced grain morphology changes due to the welding thermal cycle. The E316L electrode produced a more homogeneous and stable microstructure compared to the other electrodes. These findings indicate that the E316L electrode provides the best performance in improving toughness, hardness, and microstructural quality of ASTM A36–AISI 304 dissimilar welded joints.
