Abstract AC-pulsed gas metal arc welding may be a good option for applications that require low heat input and high productivity. The introduction of a negative polarity period assists in obtaining such characteristics, due to an increase in the wire melting rate for this polarity. The main difficulty related to the use of this version of the process is in selecting the correct welding parameters. In the scope of a medium scale (60 ft) R&D aluminum sailboat construction project, this paper deals with this issue—a tested calculation methodology for the 5087 naval aluminum alloy welding wire-electrode is proposed. By knowing the wire melting rate in both polarities, as well as the definition of some input parameters [pulse parameters, drop diameter, and negative electrode percentage (%EN)], it was possible to achieve other process variables (base current, base current time, negative current, and negative current time). The method was evaluated for different current waveforms and different negative electrode percentages. The results were satisfactory with good arc stability and the possibility of controlling the heat input in the workpiece.

About National Digital Library of India (NDLI)
NDLI logo

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.
