EVALUATION OF RESIDUAL STRESSES FOR STEEL COMPONENTS SUBJECTED TO VARIED WELDING AND HEAT TREATMENT PARAMETERS
Keywords:
Residual stress, X- ray diffraction, welding parameters, heat treatment, quenchingAbstract
Residual stresses form a major part of causing catastrophic failure among majority of the manufactured components. Residual stresses are the stresses that remain in a solid material after the original cause of the stresses has been removed. The current work involves the process of welding using varied parameters like current as well as varied quenching methods. Residual stresses were measured for each of the variable and are computed. It is observed from residual stress measurements that furnace cooling medium of quenching has shown lower values of residual stress when compared to the counterparts.
