Joining of Ramor 500 steel by submerged welding and its evaluation using the Ansys packaged software

Ansys is a simulation software program used in the engineering fields. This program is used after the modeling phase and allows to test in the virtual, i.e. program, environment before the prototype is generated. Simulation of the welded structure is one of the most important subjects of the studies conducted on welding process. In this study, the complex situations encountered in the welded structures are tried to be solved with the help of computers by using Ansys finite elements method and numerical analysis and mathematical models. After the submerged welding; radiographic examination, mechanical properties and microstructures of the samples were investigated by using tensile test, optical microscopy, and SEM and the hardness distribution was determined in the weld metal by Vickers hardness scale. SEM-EDS-XRD analyses were carried out for the structures of the samples which showed characteristic in the weld metal. The fracture surfaces of the samples of the welded joints subjected to tensile test were investigated by using SEM and thus the fracture type was determined. Thermal and mechanical analyses were performed by generating the model of the welded joints in Ansys packaged software.
