@@@@Porosity and cracks usually occur during laser cladding repair abraded shaft journal of rotating equipments of thermal power plant, greatly affect quality of cladding layer. In this paper, with experimental analysis, forming mechanism and types of porosity and crack behavior of cladding layer were studied and summarized. Several methods are introduced to reduce and control porosity and cracks; helps increase structural strength of cladding layer, improve repair quality.
