“…So that, its strength is low. This is because in the joint area occurred the concentration of stress on the weld [21][22]. So that the mechanical properties change such as ductile properties change to brittle, thus during the tensile test the joint area easily to break.…”

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.

“…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 outcomes showed that, the mechanical properties; such as the UTS, yield strength and elongation percentage of the welded specimens, were remarkably influenced by different welding electrodes. They concluded that the fracture toughness of welded specimen in E6013 join was found to be better compared to the welded specimen in E7018 join and the specimens that welded using the E6013 electrode displays better UTS [3].…”

This research was significant as it extensively studies the effects of current and rod diameter on SMAW welded join. The Mild Steel (AISI 1018) was used as the base material to be welded using the E-6013 welding rod. The experiment was constructed according to the full factorial design of experiment (DOE). This project found that the current and rod diameter are the significant factors in affecting the ultimate tensile strength (UTS). New contribution from this research was that the rod diameter is more significant than the current in affecting the UTS of a welded joint. In addition, this research also contributed new finding by showing that the interaction between current and rod diameter as significant in affecting the UTS. This interaction was also found to be more significant that current but less significant than rod diameter in affecting the UTS of welded joint. In addition, this research showed that the tensile strength increases when the current is increased from 80A to 100A. However, the tensile strength decreased as the current is set between 110A to 130A. At the same time, the welding rod diameter of 2.5mm produced the highest tensile strength compared to 3.2mm and 4.0mm rod diameter. This research also optimised the experiment and found that the highest tensile strength obtained is 342.39 MPa, which is produced using 80A of welding current with 2.5mm rod diameter.
