Abstract

The purpose of this study was to determine the ability of the mechanical tensile strength and hardness and microstructure of the steel material Mild Steel. The electrodes used were a new electrode, the electrode was added calium compound is then heated to 100 °C, 100 ° C and heated electrode. Strong currents are used 75 A, 85 A, and 95 A, for a distance of specimen 3 mm, 4 mm and 5 mm. This study used an experimental methodology and the research conducted in the laboratory. The test results showed that the maximum tensile strength is in the condition of the electrode plus a calium compound and heated at 100 ° C, 95 A current and a distance of 5 mm , with Heat Treatment 20 minutes is 278 N/mm2 . Similarly , for the region of weld metal hardness indicates the optimal hardness using electrodes were added and heated calium compounds 100oC , current 95 A and a distance of 5 mm , with Heat Treatment 20 minutes , which is 185 VHN . HAZ hardness to areas with the same test conditions with Weld Metals, hardness value is 371 VHN.Keywords: SMAW, current, Taguchi, optimum treatment.
