Essay

The thesis is dedicated to investigation of basic physical-chemical processes occurring in the heat-affected zone (HAZ) of welded joints on nickel alloys under the effect of the welding cycle. The mechanism of initiation and propagation of cracks in the HAZ of fusion welded joints were studied. Methods of evaluation of a set of crack resistance, strength and ductility characteristics were developed and tested. The data generated make it possible to increase resistance to formation of cracks in HAZ of a welded joints on alloys with a limited weldability by the fusion welding methods, through controlling the structural components before welding and during the welding process.
