| Description
| At the beginning, this course makes an introduction to the related source of welding heat source, input heat, heat transfer, chemical reaction, residual stress and welding metallurgy, moreover, it examplifies aluminum alloy, nickle alloy, carbon steel, alloy steel and stainless steel to describe metallurgical phenomenon from weld fusion zone and partial fusion zone to the welding process which is influenced by heat energy. Its main subjects include solidification, crystal structure, second particle structure, phase deformation, segregation, solidified cracks, hot check, reheat check, hydrogen embrittlement, recrystallization, heat treatment property, etc..
