Welding metallurgy book (pdf) by sindo kou – the premier reference for welding metallurgy, completely revised and expanded since its initial publication in 1987, welding metallurgy has been the standard text for the instruction of welding in technical schools and as a reference for professional welders. Though a welding arc is normally bell shaped but considerable fluctuation in its shape may take place in those welding processes where the rod electrode (called just the electrode in the rest of the text) is consumable, for example, in shielded metal arc welding and gas metal arc welding. Introduction to the physical metallurgy of welding deals primarily with the welding of steels, which reflects the larger volume of literature on this material however, many of the principles discussed can also be applied to other alloys.
