Residual Stresses and Distortions of Welding Process: Simulation of Martensitic Steels

D V Paleshwar;Suresh Akella, T. Mohan Das, ACS Kumar


Martensite steels are required for high temperature applications where hardness is required. In this study, four grades of Martensite steels are compared in a 1D model simulation of welding, where a sequential thermal and structural analysis is done. The welding heat flux with thermal boundary conditions gives the temperature distribution. The structural boundary conditions along with lateral welding process are taken as a parameter variation direction, applying symmetric conditions. Thermal Load Affect is carried out for structural variations of distortion and stress as a decoupled system. All calculations are done in MS Excel. The thermal stresses are about 30 times more than the elastic stresses causing the residual stress affect
