摘要

This chapter begins with an overview of major welding processes, establishing a foundation for linking practical techniques to the underlying scientific principles. The core discussion focuses on the metallurgy of fusion welding, where previously introduced solidification concepts are adapted to the unique thermal environment of welding. The chapter details the distinct microstructures found in the weld metal zone and the transformations occurring in the heat-affected zone, supported by case studies involving various classes of metal alloys.
