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

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.
