Friction stir welding reveals defect detection in welded joints of nickel alloys, suggesting improved control methods.
The design of rotor blanks made of heat-resistant nickel alloys welded by a promising method — friction stir welding — has been analysed. The most characteristic types of defects, the occurrence of which is possible at this welding method, and their preferential orientation are demonstrated. For detection of such defects the scheme of diffraction method of control is offered. Its applicability on the sample with artificial and natural defects is shown.
