Abstract

The better welding results are always a scientific challenge in welding engineering. This is to ensure the connection functions properly according to its designation. The main purpose of this study was to determine the effect of electrode drying temperature on the mechanical properties of ASTM A36 steel weld joint. This research was conducted at the Condet Welding Training Center and PT. Gamma Hepsi Condet. The tests carried out were visual tests, radiographs, and tensile tests. The results showed that the drying of the electrode E 7018 without an oven had a lot of welding defects on the inside in the form of porosity about 2 mm. The results showed that the highest tensile strength of 50.01 kgf/mm² was found in specimens using an electrode drying temperature of 230ºC.

Abstract

This study investigates the effect of the increased welding layers welded by the SMAW process on distorsion, thickness, microstructure, hardness, and corrosion. The method used in this research is experimental. Low-carbon steel with a size of 150x10x10 mm was welded by the SMAW technique using an HV 450 electrode. Variations in the welding layers are single, double, and triple. The three variations of the samples were observed with a digital camera and an optical microscope. Moreover, samples were tested with a hardness tester. Corrosion testing was also carried out to determine the corrosion rate of the layers formed. The results showed that the number of SMAW welding layers affected the thickness, phase, hardness, and corrosion rate. The hardness of one layer is less than that of thicker specimens, while the corrosion rate of three layers is lower than that of less-thick samples.

Abstract

Medium carbon steel is widely used due to could conduct heat treatment to modify the microstructure and mechanical properties. Quenching is one method to modify the microstructure and mechanical properties. In the present study conducted heating samples at 850°C using an electric furnace, then held them for 60 minutes and quenched in various media (saline water, oil, and distilled water). Afterward, the quenched sample was investigatedmicrostructure, hardness, and corrosion using an optical microscope, Vickers hardness tester, and weight loss method. 5% NaCl quenching media could result in samples more uniform and martensite due to the high cooling rate.More uniforms and martensite have the beneficial highest hardness and lowest corrosion rate for around 762.4 HV and 76.04 mpy.

Abstract

This study aims to determine the effect of the addition of chromium in the SMAW process to the tensile strength, hardness value and macro structure of the low carbon steel welding joint using E6013 electrodes. The research procedure begins with the process of welding, making seam, making specimens: tensile test, hardness test and macro structure. Furthermore, the process of tensile, hardness and macro structure testing is carried out. The tensile strength value of the weld joint with the addition of chrome tends to be slightly smaller than that of the weld without the addition of chrome. The maximum tensile stress and elasticity limits for welded joints with added chrome are higher than for welded joints without added chrome. The addition of chrome to the welding process has been shown to increase hardness. In the macro structure, porosity did not occur both specimens with the addition of chromium and without the addition of chromium.

Abstract

Hardfacing over carbon steel was carried out using the SMAW apparatus. The sample was hard-faced with a single layer using HV 800 electrode with a 1G weld position. Different welding currents were used, such as 90, 100, and 110 A. After the weld, the sample was quickly immersed in distilled water. Cooled samples were cleaned with a chipping hammer and a wire brush. Afterwards, the samples were cut for hardness and corrosion testing. The highest hardness in the sample was welded using 110A, while the lowest hardness was welded using 90A. Increasing the current from 90 to 110 A could increase hardness by approximately 2.31%. The lowest current was used during welding, resulting in a lower corrosion rate. This means that the welding layer produced at the lowest current has greater corrosion resistance than that produced at higher currents. Reducing the current from 110 to 90 A could reduce the corrosion rate by approximately 44.33%. Finally, all three specimens meet the "good" criteria of corrosion resistance.

Abstract

Microstructure modification of the plain carbon steel usually enhances hardness and corrosion resistance. Therefore, in the present research, the microstructure of plain carbon steel is modified by heating it in an electric furnace using various temperatures and then quenching it in engine oil to enhance corrosion resistance and hardness. Several characterizations were conducted, such as microstructure, hardness, and electrochemical behavior. The microstructure evolution indicates a clear transformation of martensite morphology with decreasing austenitizing temperature. Decreasing the furnace's heating before quenching could increase the specimens' hardness and corrosion resistance, with values around 586.36 HV and 0.135 mmpy. Therefore, the optimal heat treatment condition for plain carbon steel components in marine environments was found at 800 °C based on the results of this study.

Abstract

AISI 4140 steel is widely used in engineering and marine components due to its high strength and good hardenability. However, improving hardness through heat treatment may influence the corrosion behavior of the material in chloride containing environments. This study investigates the effect of NaCl concentration as a quenching medium on the microstructure, hardness, and corrosion behavior of AISI 4140 steel. The samples were austenitized at 1000 °C for 15 minutes and quenched in NaCl solutions with concentrations of 3.5%, 7%, and 10.5%. Microstructural observations were carried out using optical microscopy after etching with 3% Nital. Hardness testing was performed using the Vickers method with a 10 kg load, while corrosion behavior was evaluated using weight loss measurements and electrochemical tests in 3.5% NaCl solution. The results show that increasing NaCl concentration produces a finer martensitic structure and increases hardness from 673 VHN at 3.5% NaCl to 762 VHN at 10.5% NaCl. However, the corrosion rate also increases from 0.3688 mmpy to 0.3990 mmpy, indicating higher electrochemical activity at the material surface. These results demonstrate a trade-off between improved hardness and reduced corrosion resistance with increasing NaCl concentration.
