| Abstract | In this experimental work, the effects of line energy at constant scan speed on quality of bead-on-plate laser welding of NiTinol sheets were investigated. Variations of bead geometry, changes in microstructure, variation of micro-hardness value along the weld-bead, generation of new phase during welding, changes in tensile strength of the welded samples, corrosion behavior of welded and parent material, and changes in phase transformation temperatures were measured for characterization of welded samples. Laser weld-bead profile was changed from a wine glass without base to glass shape with the increasing line energy. Quality aspects of weld-bead geometry quality aspects showed an increasing trend with line energy. Microstructure was changed during welding due to competitive grain growth. Microhardness values gradually increased from weld centre line to base metal. Tensile strength of the material was reduced after welding due to the formation of brittle intermetallics compounds. A dual failure mode for the welded sample was observed; whereas a single mode of failure was detected for parent material. The corrosion properties of the welded samples were found to be better than that of parent material. Phase transformation temperatures were also found to be reduced after welding. |

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.
