| Abstract | An hourglass-like heat source model is developed to simulate the geometry of weld beads of laser beam welding. The welding experiments with different welding parameters were carried out to find whether the welds are full-penetrated or not. The laser powers ranged between 1.0 and 5.0 kW with steps of 1.0 kW. Five levels of the welding speed were used: 1.0, 2.0, 3.0, 4.0, and 5.0 m/min. The numerical analysis based on finite element method was used to predict the shape of weld pools during welding. To give a better representation of weld bead, an hourglass-like heat source model is developed to describe the unique shape of 1060 steel weld bead for laser beam welding without filler metal instead of the commonly used conical heat source. Comparing the predicted fusion profile with the experimental cross section of weld, it is found that hourglass-like heat source model is more consistent with the experimental results than the conical heat source for 1060 steel. In addition, the best heat source parameters are obtained by an error analysis. Compared to the experimental results, the simulated results for the welds using Power = 4000 W and Speed = 2.0 m/s and 5000 W and 2.0 m/s match the experimental results well. |

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.
