“…After surveying the former literature, articles [11,12] were found dealing with the study of the influence of electrode type on the microstructure and mechanical behavior of austenitic stainless steel welds achieved using the SMAW process. Other researches [13][14][15][16][17] have focused on shielded metal arc low carbon steel welds by the use of different electrodes. The significant influence of electrode type and welding current on the microstructure and mechanical properties of these welds has been clearly revealed.…”

Recently, low alloy steel types have been widely utilized in the manufacture of many important products, which may be damaged during service and require repair by welding. Shielded metal arc welding of 6 mm thick AISI 5155 low alloy steel plates with different electrodes was employed to examine and compare the microstructure and mechanical properties of the welds. The results showed diverse microstructures over the weld metals. The maximum hardness values across the welds were in the CGHAZ, where the structure contained ferrite and pearlite coarser than that of the base metal. The finest structure was in the inter-critical HAZ, in which the minimum hardness was; where partial spheroidization of pearlite occurred. The average weld metal hardness value, for all welds, was lower than that of the base metal (~465 HV). The highest hardness value was (~337 HV) for the weld produced using the OK48.00 electrode, whilst the maximum tensile strength was (938 MPa) for the weld due to the use of the OK76.18 electrode. The low cost electrode (OK46.00) and the expensive one (OK92.18) gave relatively lower mechanical properties, whereas the optimum properties were achieved as a result of using iron powder low hydrogen covering electrodes (OK48.00 and OK76.18).

The purpose of this study is to analyze the welding defects that occurring in the SMAW (Shielded Metal Arc Welding) process. This study used experimental method to investigate the various types of electrodes and welding current. The welding process in this study used ASTM A36 low carbon steel with specimen dimensions of 8 mm thick, 80 mm wide, and 100 mm long. The welding process was carried out in an underhand position (1G) using a V-seam layer with a SMAW welding machine, which a sliding adaptive two axis system with speed control. The types of electrodes used were E6013 and E7018 electrodes with a diameter of 3.2 mm. The current variations used 90 A, 105 A and 120 A. The test methods used the Penetrant Test, Visual Test (Non Destructive Test) and Tensile Test (Destructive Test). The results of this study were: 1) the welding defects that often occurring at the E6013 electrode due to undercut and at the E7018 electrode caused by the porosity, 2) at a current of 120 A the occurrence of welding defects was minimal, and 3) the tensile strength of E7018 was greater than E6013.

The aim of this study is to determine the effect of variations in welding current strength on the tensile strength of ABREX 400 steel weld joints. The results of this study are expected to give contribution toward the world of metal welding, especially low carbon steel metal welding which will later be beneficial for the development of the metal industry and technology. The method used in this research was the experimental method. In addition, the process of welding the material used SMAW welding and the type of seam V connection and the variations in the current strength used are 90 A, 100 A, and 110 A. The specimen used was a TRS 400 low carbon steel plate with a thickness of 10 mm and the electrode used was the E7018 electrode Ø 3.2 mm. The standard specimen used was ASTM-8 and the test was carried out using the Universal Testing Machine tensile test device. As a result, the research showed that the tensile strength at a current of 90 A was 588.91 N / mm2, a current of 100 A was 570.56 N / mm2, and a current of 100 A was 545.17 N / mm2. Based on the results of the research, it can be concluded that welding using a current strength of 90 A produces the highest tensile strength value, namely 588.91 N / mm2 compared to currents of 100 A and 110 A.
