Abstract | An experimental investigation on laser transmission welding of polycarbonate is presented in this paper. Instead of concentrating on the well-known effects of process parameters, the present study focuses on the sensitivity analysis of process parameters to identify the critical parameters and to assess their relative impact on the variation in output quality. Curvilinear regression models are developed using the independently controllable design variables like laser power (W), welding speed (mm/s), standoff distance (mm), and clamp pressure (MPa). Selected weld quality characteristics, namely the weld strength (N/mm), which is calculated based on failure load per unit length and weld width (mm), are used to set the objective functions. Parametric sensitivity analyses are performed using the developed models. It is observed from the results of sensitivity analysis that the weld strength is more sensitive to welding speed (sensitivity of 8.4 N/mm per unit welding speed) and laser power (sensitivity of 3.08 N/mm per unit laser power), whereas weld width is more sensitive to welding speed (sensitivity of 0.37 mm per unit welding speed) and standoff distance (sensitivity of 0.11 mm per unit standoff distance), respectively. These are the critical parameters for the respective quality characteristics, and a small variation of these parameters causes relatively higher deviation in weld quality. |

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.
