Comparative Analysis of GTAW, GMAW, and FCAW Welding Results on A36 Steel Against Tensile Test and Macrostructure

Offshore building construction is inseparable from the fabrication process. Fabrication process that has an important role in terms of engineering, material repair and welding In offshore construction, a precise method needed on A36, where A36 steel one main materials buildings. this study comparison results GTAW, GMAW, FCAW against Tensile Test Macrostructure Test. The research show best tensile test are GTAW with average value ultimate strength 462,168 MPa. testing which widest HAZ width 18,71 mm.
