Welding Engineering Prof. Dr. D. K. Dwivedi Department of Mechanical and Industrial Engineering Indian Institute of Technology, Roorkee Module - 5 Heat Flow in Welding Lecture - 5 Residual Stress – I In this module 5th based on the Heat Flow in Welding is the 5th lecture and this lecture is based on the Residual Stresses. In this presentation mainly we will be taking about the residual stresses being developed in the weld joint and different mechanisms, that lead to the development of the weld joint. And in which way these residual stresses affect the performance of the weld joint and at the end, we will try to see that, how these residual stresses can be reduced in order to avoid the adverse effect on the performance of the weld joint. (Refer Slide Time: 01:09) So, this as far as content is concerned, this presentation will include, first trying to understand that what are the residual stresses and how do they effect the performance of the weld joint. Then mechanism of the residual stresses, mechanisms that lead to the development of the residual stresses, then the different types of the residual stresses and effect of residual stresses on the performance of the weld joint and what methods can be used for controlling the residual stresses.
