The bondability by the method of seam friction welding of the combinations of heat resistant nickel VCNA-1VP alloys and EP975-ID is considered. The optimum parameters of seam friction welding are determined. The radiographic control of welds is carried out, The stress-strain properties at a bend and stretching are analyzed, a weld structure is investigated. The character of sample destructions is determined. The qualitative and quantitative micro-X-ray analysis is carried out and sample micro-hardness of a weld is examined.
