| Abstract | Application of high strength steel is one of the most promising solutions to the problem of vehicle weight reduction. However, weldability problems occur when three sheet metals of the high strength steel are welded. This is because under such situation, the suitable welding range in the lobe diagram is too narrow and the strength between the contact zones is lower than the required value, and also, expulsions between the sheets occur. In this work, a conically shaped hollow electrode was applied at the lower electrode to improve resistance spot weldability of three-sheet welding including high strength steel. Shear strength test and analysis of welding signal and weld cross section were conducted. It was found that the proposed lower electrode has some advantages in welding the three-sheets welding compared with conventional electrodes or hollow electrodes. Consequently, a welding process using the proposed electrode was studied and verified with numerical analysis. |

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.
