Abstract

Drying of electrodes on the mechanical properties of ASTM A36 steel concerns toughness and hardness value. This research used the experimental method. The tests conducted include a test without damage using radiography and a destructive test using hardness test. As many as 12 samples were divided into four variations in the temperature of drying electrodes, using low carbon steel, ASTM A36. The results showed that the electrode drying of the E 7018 without being opened had many welding defects on the inside in the form of Porosity Ø 1mm, elongated 5 mm. The highest hardness test results on a metal base found on ASTM A36 steel plate SMAW joints which was carried out by electrode drying process with a drying temperature of 230∘C, with a hardness value of 158 VHN. Violence test on the highest weld metal found in the ASTM A36 steel plate SMAW joins the electrode drying process with drying temperatures of 260∘C, with a hardness value of 162.6 VHN.
