Abstract

The thermal field has a major influence during the welding process. The heat transfer resulting from welding has an influence on the metallurgical and mechanical properties of steels and welded joints. The most affected regions are: fusion zone (FZ) and heat affected zone (HAZ) due to high temperatures to structural transformations of welded joints. The research is based on the theoretical investigations on high-temperature welding areas through MAG-M mechanized butt welding with solid wire of the naval high strength steel, EH 36. For theoretical research, a model with 3D finite elements was used. For the welded joint, the filler technique was used, which means the filler material is modelled with finite elements. The finite elements are activated when the heat flow passes through them.
