چکیده
This research uses shielded metal arc welding (SMAW) method combined with flux core art (FCAW) using ASTM A36 10 mm steel material and double V seam. Then the electrode used in this study is for SMAW E7018 welding. , while FCAW E71T1 The current variations are 60A, 75A, 90A 190A, 205A, 220A. purpose of to determine optimal that produces highest tensile impact strength differences microstructure weld area. From results study, strengths were at 220A a 526.96 N/mm an 1.2044 J/mm2. formed Grain Boundry Ferrite (GBF), Pearlite (P), Arcicular (AF), (F). Where percentage 72.1% 27.9% Pearlite, it 75.63% 24.37% Pearlite.
