Comparative Analysis of Welding Mechanical Properties FCAW Welding Joint of A36 and A53

Abstract A36 and A53 steels are low carbon steel with relatively similar percentage, respectively 0,25-0,30% 0,25-0,29%. Both often used within the marine industry. The objective of this research is to figure out effect variation groove angle heat input process welding two different plates towards a metallography, tensile, bending test E71T electrode, as well figuring weld 18 mm thick plates. 55°, 60°, 70° 140 180 A. Results experimental study shows that specimen A largest sum HAZ length, which 8,4 mm, perlite phase, respectively, 67% base metal, 65% on HAZ, 62% metal,63% 66% metal. open defect value in tests 1.87 owned by specimens 55°
