Abstract

Metal joining is a process carried out to connect 2 or more metal parts of a similar or dissimilar metal. Connection strength is the goal of the process of connecting metals or materials. SMAW welding is a process of connecting metals or materials using heat energy. The purpose of this study was to determine the effect of welding currents on the tensile strength of AISI 1050 and ASTM A36 material links. In this study, test data show that in the welding process using 120A current the tensile strength value is 51.27 kgf / mm2, followed by welding using a current of 140A with 49.31 kgf / mm2, and welding using a current 160A 48.25 kgf / mm2. In tensile testing of welding current variations with currents 120A, 140A, and 160A, all fractures approach the welded joint. From the test data it can be concluded that the current affects the tensile strength of the material which the process is affected by arc voltage, current magnitude, welding speed, magnitude of penetration and electric polarity. Determination of the amount of current in connecting metals using arc welding affects the efficiency of the welding results.Keywords: SMAW Welding, Tensile Testing, AISI 1050 Steel and ASTM A36                                                          AbstrakPenyambungan logam adalah suatu proses yang dilakukan untuk menyambung 2 bagian logam atau lebih baik logam yang sejenis maupun tidak sejenis.

Welding is an activity of joint two or more metal parts by heating or pressing or a combination of the two in such a way that they merge like whole objects. The strength of the welding joint is a prerequisite for a construction especially in the oil and gas industry such as in piping installations and pressurized tanks. The welding procedure and its parameters is a matter that greatly affects the strength of the welded joint. This study aims to determine the strength of the double lap joint to the SMAW welding results on AISI 1050 steel with 7016 electrodes. Current variations used in this welding process are 100A, 125A and 150A. The results showed that the welding current greatly affected the strength of the weld joint, this can be seen from the value of the tensile stress strength where the highest value in the specimens welded with a current of 100A was 74.05 kgf / mm2, while for the lowest tensile stress on the specimen with a welding current of 150A with a value of tensile stress of 68.60 kgf / mm2. The results of the fracture form after the tensile test does not occur in the weld metal area and the shape of the fracture that occurs can be categorized in the form of brittle fracture.

Abstract

The effect of tempering temperature variations on the hardness of the blade has been carried out on SUP 9A leaf spring steel material. The tempering process was carried out at temperatures of 300°C, 400°C, and 500°C with a holding time of 15 minutes and cooled in free air. Specimens without heat treatment and tempering results were tested for hardness using the Rockwell hardness test method and microstructure analysis using an optical microscope. From the results of the study, it was found that the hardness value obtained on the raw material specimen without heat treatment obtained a hardness value of 60.50 HRC, while the tempering temperature variation obtained the hardness value on specimen B (tempering temperature 300°C) of 66.90 HRC, specimen C (tempering temperature 400°C) of 64.70 HRC, while specimen D (tempering temperature 500°C) obtained a hardness value of 65.80 HRC. From the results of the specimen hardness test, the hardness value after heating was higher than the hardness value without heating treatment. Microstructural analysis shows that the higher the given temperature, the larger the grain of the steel structure looks. Without heat treatment the microstructure of the specimen is an irregular black bainite. Meanwhile, by heat treatment, the microstructure of the specimen is irregular black martensite.

Abstract

This work aims to prepare and characterize polyurethane nanocomposite sequences modified with bentonite as fillers and palm oil as a soft segment component while Toluene Diisocyanate (TDI) was chosen as a hard segment component. Bentonite fillers are needed to provide heat resistance to the polyurethane coating. Morphological, structural and thermal polyurethane nanocomposites are characterized by SEM, FTIR, and TGA. FTIR analysis is the NH urethane group in palm oil polyurethane compounds while the absorption of C=O urethane group widens at 1735 cm-1. While the CH group occurs at absorption wavelengths of 2120-2180 cm-1, adding bentonite (7% by weight) is completely laminated and well dispersed in the form of a mixture of peeling / intercalating layers in the polymer matrix. Polyurethane nanocomposites have a morphology separated by clearer microphase. The resulting thermal stability is higher compared to the addition of bentonite 3 and 5% by weight. Because of its enhanced features, the polymer developed can be considered a material with heat resistance as a coating.
