This handbook presents a comprehensive and technically rigorous treatment of welding and welding technology, integrating foundational principles with industrial applications across manufacturing and fabrication sectors. It explains the scientific basis of heat generation, metal fusion, joint formation, and metallurgical transformation that govern welding processes. The discussion addresses arc and resistance methods, power supply systems, and process selection criteria, linking theoretical understanding with practical execution. Emphasis is placed on weld integrity, inspection procedures, and mechanical testing to ensure structural reliability and safety. The handbook further examines design considerations, manufacturability principles, and the relationship between welding techniques and engineering performance. By combining materials science with applied engineering analysis, it establishes a structured framework for understanding how welding technologies support structural fabrication, production efficiency, and quality assurance in modern industrial environments.

Structured as a technical reference for engineers, technologists, and advanced students, the handbook strengthens practical competence, analytical decision-making, and process optimisation. It supports the development of durable welded structures and promotes precision, safety, and innovation in contemporary engineering applications.
