Abstract
Crystallographic texture and microstructure of fusion welded joints were studied. Criteria were selected for estimation of the degree of inheritance of structural state of the base metal by the weld metal. Factors determining the degree of such inheritance were established, and conditions for a minimum distortion of the structural state were identified.
Keywords: fusion welding, metal solidification, crystallographic orientation, single-crystal state, X-ray examinations, disorientation, dislocation density, inheritance of structure, weld mg cond itions
