Pengaplikasian baja corten A pada cerobong pembuangan emisi pada kapal Barge Mounted Power Plant (BMPP) membutuhkan sifat-sifat tertentu. Material baja corten A memiliki sifat ketahanan panas yang baik karena memiliki unsur Cu. Proses pengelasan dan pemilihan elektroda sangat berpengaruh pada hasil las yang diinginkan. Penelitian ini dilakukan dengan tujuan untuk menganalisis bagaimana pengaruh variasi elektroda dan arus terhadap hasil pengelasan baja corten A terhadap struktur mikro, ketahanan korosi, dan sifat mekanik. Adapun variasi logam pengisi yang digunakan adalah ER70S -G dan ER80S -G. Pengelasan yang digunakan adalah metode Gas Tungsten Arc Welding (GTAW). Skema eksperimen didasari dengan Welding Procedur Spesification (WPS) yang telah ada. Setelah eksperimen pengelasan, dilanjutkan dengan pengujian metalografi, pengujian tarik, pengujian kekerasan dan pengujian korosi pada temperatur 374℃ dengan gas CO2. Hasil penelitian korosi temperatur tinggi menunjukan bahwa laju korosi mengalami penurunan. Laju korosi terendah terdapat pada spesimen dengan pengalasan menggunakan logam pengisi ER80S-G dan arus 140A. Untuk hasil tertinggi niilai UTS dan nilai kekerasan terdapat pada spesimen D-3 yaitu pengelasan menggunakan logam pengisi ER80S-G dan arus 140A.

In this study, related to getting better obtain to the mechanical properties of medium carbon steel joints joined by MIG welding method using the Taguchi method welding groove were optimized. Grove angle (60ᵒ, 75ᵒ and 90ᵒ), current (100 A, 110 A and 120 A) and voltage (25 V, 30 V and 35 V) were used as welding parameters. The results showed that the highest tensile strength as 597.963 MPa was obtained at groove angle 90ᵒ, current 120 A and voltage 30 V, the lowest tensile strength was obtained as 395.125 MPa. The highest elongation as 11.551% was obtained at groove angle 90ᵒ, current 120 A and voltage 30 V, the lowest elongation was obtained as 8.354%. In addition, it was observed that the changes in current and voltage values significantly affect the tensile strength and elongation values of the joints. According to ANOVA analyses, the most effective parameter on average tensile strength and elongation were determined to be groove angle (62.75% and 75.58%, respectively). Based on S/N ratios, the optimal parameters for average tensile strength and elongation were determined A3B3C2 factors.

“…In particular, submerged-arc welding (SAW) with relatively high welding efficiency is extensively used to weld medium and thick plates. The composition of atmospheric corrosion resistant electrodes is generally kept similar to that of the base metal (BM) to ensure a matching of corrosion performance, which has undergone melting, high temperature retention, rapid cooling, etc during the welding process [8]. However, the atmospheric corrosion resistant electrodes contain more Si [8,9], Cr [10], and other alloy elements, and it is easy to form coarse granular bainitic ferrite (GBF) and more hard phase martensite/ austenite (M/A) constituents during the phase transition process [11,12].…”

This study aims to elucidate the appropriate heat input (Ej) range for submerged arc welding (SAW) of high-performance weathering steel. Generally, by increasing Ej, the welding efficiency can be improved, but the toughness of the weld metal may be deteriorated. Therefore, SAW was employed to produce the weld microstructure under varying Ej from 20 to 50 kJ/cm. The Charpy V-notch impact tests were conducted at −40℃, and the weld microstructures were characterized by optical microscopy (OM), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and electron backscatter diffraction (EBSD). The results indicate that the weld microstructures consist of polygonal ferrite (PF), acicular ferrite (AF), granular bainitic ferrite (GBF), and martensite/austenite (M/A) constituents under each Ej. With the increase in Ej, the proportion of PF increases, while AF and GBF are coarsened, and the area fraction (fM/A) and mean size (dM/A) of M/A constituents increase monotonically. Further, the fraction (fMTA>15°) of high-angle grain boundaries (HAGBs) with the misorientation tolerance angles (MTAs) greater than 15° is reduced, while the mean equivalent diameter (MEDMTA≥15°) of ferrite grains with HAGBs increases. Accordingly, with the increase in Ej, the impact toughness of weld degrades from 128.4 to 47.6 J. The higher degree of micro-strain concentration caused by the increase in M/A size and area leads to the formation of larger microcracks under small plastic deformation, while the reduced HAGBs have a lower inhibition effect on crack propagation. Finally, the impact toughness decreases with the increase of Ej. Overall, the findings suggest that the Ej of SAW should not exceed 40 kJ/cm in the construction of high-performance weathering steel.
