About
Tushar Sonar is a materials and manufacturing engineer whose research focuses on advanced welding processes, particularly the development and optimization of activated tungsten inert gas (A-TIG) welding techniques for joining dissimilar metals. His work addresses critical challenges in power plant and structural applications, where joining ferritic-martensitic steels (like P91) to austenitic stainless steels (like 304L) is essential but traditionally plagued by high heat input, distortion, and cost. Sonar’s most cited paper (2024, 7 citations) demonstrates how robotic A-TIG welding can enhance productivity and mitigate distortion in these dissimilar welds, offering a more efficient alternative to conventional multipass TIG welding. By reducing heat input and joint preparation requirements, his approach lowers manufacturing costs and cycle times while improving weld quality. This work has direct implications for the energy sector, where reliable, cost-effective joining of high-temperature steels is critical. Sonar’s contributions advance the practical application of automated welding technologies, bridging the gap between laboratory research and industrial implementation. His findings are particularly valuable for researchers and engineers seeking to improve welding productivity in power generation and heavy fabrication industries.
