The aim of this paper is to demonstrate the influence of butt welding shapes on the corrosion rate, microstructure and temperature of carbon steel type St37.The double butt welding was performed by V angles 15°,30° and 45°. The finite element analysis via ANSYS software is performed, this analysis includes a finite element model for the thermal welding simulation. The temperature distribution was obtained. From the results of the microscopic structure it is evident that the geometric shape has an important role in the welding process, when the geometric value of the welding region gets bigger, the faults get less due to increase of heat quantity in the welding region and the corrosion rate for the rain water is less than of sea water. The work presents the finite element model for numerical simulation of welding in carbon steel St37 double butt welding.
