摘要：The aimed of this research are to compare physical dan mechanical properties between raw materials and Shielded Metal Arc Steel Weld Metals and to find optimum temperature of annealing. A series of Shielded Metal Arc Steel Weld Metals were made on 3 mm of Thick A 287 carbon steels. The electrode used was E 6013, Ø 3.2 mm. Annealing was performed with three different temperature were 300°C, 600°C, dan 850°C. The results show that the tensile strength of raw material had the same value with weld metals and weld metals with annealing 300°C and 600°C, but weld metals with annealing 850°C had lower tensile strength. The hardness experiments was used Vickers Micro Hardness.The Hardness number of weld metals was higher than HAZ and raw materials. Weld Metals with annealing 300°C had the highest value. The elongation of weld metals and weld metals with annealing 300°C and 600°C had lower number than raw materials, but weld metals with annealing 850°C had almost the same value of elongation with raw materials. The optimum annealing temperature was 850°C because weld metals with annealing 850°C had high elongation and low tensile strength.Keywords SMAW, Annealing, Vickers Micro Hardness, Tensile Strength, Elongation.
