This book volume presents a comprehensive collection of selected proceedings of the National Conference on Challenges in Welding and Additive Manufacturing (NCWAM 2025). These papers represent cutting-edge research in the fields of additive manufacturing (AM) and welding. In the area of AM, papers are in the area of both laser-assisted additive manufacturing, wire arc additive manufacturing (WAAM), structure property correlation of products of different materials produced using AM route, process optimization, modelling of process, application of AM techniques in various industry sectors like defense, space etc. Key highlights include, the optimization of laser powder bed fusion processing of BZL12Y superalloy, addressing porosity reduction of AlSi10Mg for defense applications, and exploring the challenges of single-jet sub-zero AM processes. The volume also delves into the role of heat treatment in enhancing the microstructure, corrosion resistance, and fatigue behavior of additively manufactured materials such as 17-4 PH stainless steel, IN718, and 316L stainless steel. In the area of WAAM, there are papers on the metallurgical and mechanical properties of WAAM-deposited AZ31B alloy and the experimental investigation of Inconel 718 cladding on mild steel substrates using CMT-based WAAM, showcasing its potential for large-scale industrial applications. In the area of welding, the sections include manuscripts on advanced welding techniques, including activated tungsten inert gas (A-TIG) welding, rotary friction welding and dissimilar welding, which are investigated for their potential in fabricating high-performance joints and cladding layers. This book volume serves as a valuable resource for researchers, engineers, and industry professionals, offering insights into the latest advancements and future directions in additive manufacturing and welding technologies.
