S. V. Nadkarni - Modern Arc Welding Technology, 2nd Edition

Welding is a small but crucial part of metallurgy i.e. the science of discovering new metals and working efficiently with them. The welding specialist has to have an intimate knowledge of the properties, structure and behaviour of each metal as also new alloys and exotic variants for specific industries and applications. When metallurgy moves to the next phase of metal-working there are many skills and processes that need to be mastered. This is why in the middle ages there were no books but there were guilds where the masters taught know-how through a process of show-how . Today s equivalent is the knowledge volume in hardcopy (book) form or digital storage.
