Welding is the connection of the two metal materials into one, using a heat process without any pressure, defined as a metallurgical process. In the world of industry and metal welding which is used to construct construction is low carbon steel as the base material, and fracture is the nature of steel. This study aims to determine the effect of the type of electrode and current strength on the mechanical properties of welding results on ASTM A36 Steel. This research uses experimental research methods. In the welding process using ASTM A36 steel material on a specimen with a size of 100 mm x 25 mm x 8 mm in a flat / flat position (G1) using V. The type of electrode used is RB 2.6, RB 3.2, and LB 52 2.6 with variations in the flow of 70 A, 80 A and 90 A, which are then carried out by tensile test. The results of the research that have been done show that the value of tensile strength at the RB electrode 2.6 with a welding current of 70 A is 355.504 Mpa, 80 A is 439,795 and 90 A is 472,011 Mpa. For RB 3.2 electrodes with a welding current of 70 A of 263,955 Mpa, 80 A of 376,981 Mpa, and 90 A of 342,362 Mpa. At LB 52 2.6 electrodes with a welding current of 70 A at 478,974 MPa, 80 A at 484,172 Mpa, and 90 A at 485,152 Mpa. According to the data, it can be seen the results of welds using LB 52 2.6 electrodes at 90 A currents, with a tensile strength value of 485.152 MPa, a stretch value of 27.5%, and an elastic modulus value of 1764,190 N / mm 2 .
