| Abstract | With the promotion of weight reduction, hydroformed tubes have been widely used in vehicle construction. Because of different section shapes in hydroformed tubes, sheet to cylindrical tube joining process by single-sided spot welding (SSSW) is proposed in the present paper. However, because of line contact status and low structural stiffness, welding deformation often occurs. As a result, doughnut weld nugget is formed, and welding quality is affected. In this study, the microstructure and microhardness of the doughnut weld nugget are investigated, and the weldability of high-strength steels sheet to cylindrical tube SSSW with different electrode force, tube thickness, and radius is explored, respectively, through the analysis of dynamic electrical resistance. Because of special structural characteristics, the weld lobe for sheet to cylindrical tube SSSW is very narrow. Owing to high dynamic resistance, the weld lobe is moved to the left with small electrode force or high tube thickness, and the weld lobe is expanded with thick cylindrical tube. With the decrease of tube radius, crack or expulsion easily occurs, and the weld lobe gets narrow. Welding time is also found to be an important parameter, which influences the weldability because proper welding time can enlarge the weld lobe. |

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.
