EFEK KETEBALAN PLAT BAJA KARBON RENDAH SS-400 TERHADAP DISTORSI FILLET JOINT MENGGUNAKAN METODE SMAW

---

This study aims to analyze the effect of variations in the thickness of SS-400 low carbon steel plates on the distortion of fillet joints using the Shielded Metal Arc Welding (SMAW) method. Welding is a widely used method of joining metals, but it often causes distortion due to uneven heat distribution during the heating and cooling processes. The plate thickness variations used in this study were 4 mm, 8 mm, and 12 mm. The welding process was carried out using an RD-260 (E6013) electrode with a constant current of 130 A to maintain the uniformity of the welding parameters. The research methods included measuring angle distortion using a dial indicator, testing Vickers hardness in the base metal, Heat Affected Zone (HAZ), and weld metal areas, as well as observing macro and micro structures using an optical microscope. The results showed that plate thickness had a significant effect on the amount of distortion that occurred. Plates with a thickness of 4 mm produced the greatest distortion, while 12 mm plates showed the least distortion. This is due to differences in material stiffness and heat distribution capabilities. The hardness values in the weld metal and HAZ areas tended to be higher than those in the base metal for all thickness variations due to the influence of the welding thermal cycle. The microstructure showed a dominance of ferrite and pearlite phases with grain refinement in the weld and HAZ areas. The results of this study indicate that increasing the plate thickness can reduce distortion and improve the stability of fillet joint welds in SS-400 low carbon steel.
