This study aims to determine the effect of welding current on the tensile strength, toughness, hardness and microstructure of SMAW welding with E6013 electrodes. This research uses low alloy steel. Welding can be defined as the process of joining two metals to the point of metal recrystallization, with or without using added materials and using heat energy as the melting of the material being welded. Welding can also be interpreted as a fixed bond of heated objects or metals. The material is given welding treatment with a current variation of 100 Amper, 130 Amper and 160 Amper by using reverse polarity SMAW DC welding with an E6013 electrode with a diameter of 3.2 mm. Reverse polarity DC, i.e. the electrode holder is connected to the positive pole and the parent metal is connected to the negative pole. The type of seam used was seam V with an angle of 70°. The specimens were subjected to tensile testing.
Key words are current, SMAW, tensile strength, toughness, E6013.
