| Abstract | Welding induced distortion is one of the critical defects in the welded structures. Angular distortion is most pronounced which badly affects the welded structures. Non-uniform heating during welding develops this angular distortion. Various methods are available to control/minimize the welding distortions. One of the methods available to control this distortion is restraining, in which clamping pressure is applied on the deforming edges of the plates. In the present study, a 3-dimensional coupled transient thermal analysis is done for simulating the restraining phenomenon of welding. The developed transient thermal heat source was used to simulate the arc welding phenomenon. The element birth and death technique was used for simulating filler material deposition. Thermal model was verified by comparing the macrograph of Finite Element Analysis (FEA) model and the weld and verification of structural model was done by comparing the measured and predicted angular distortions. Experimental and Finite Element (FE) analysis is done for both conventional welding and welding under restraining pressure. Transient thermal and non-linear structural analyses were carried out in order to predict angular distortions. The Finite Element Method analysis and experimental verification is done for manual metal arc welding process. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
