Abstract :
Welding is a technique of joinid two or more components into one desired component. Welding itself has various types, one of which is SMAW (Shielded Metal Arc Welding). How to join the arc tip of the electrode with the material to be welded by used a steel plate ASTM A36 with a plate thickness of 2 mm using an electrode type E7016 LB-520 with a diameter of 3.2. The method used is from the specimen based on the porosity test and tensile test. With the results for porosity with the highest average current at 100 amperes with a porosity value of 0.58146%, while the lowest was at 90 amperes with a pososity value of 0.45459% and with the highest Ultimate Tensile Strength read in 100 amperes with 446 N / mm² value, and the lowest Ultimate Tensile Strength at 110 amperes with a value of 420 N / mm².
