Calculation of metallurgical processes during welding

The article considers the metallurgical process during welding of materials. A study and description of the physicochemical processes of the interaction of metal with gas and slag is carried out. The process of heating, melting and cooling the base metal during welding is calculated. The process of crystallization of a metal during the formation of a welded joint is studied and described. Researched Steel 30XMA. After the calculation study, a conclusion was drawn on the structure and properties of the sections of the base metal adjacent to the seam
