Abstract

The article presents the results of a study of deformation welding processes of blanks made of EP718-ID alloy. Before upsetting, the blanks were soldered to protect the mating surfaces from oxidation and to improve the quality of the weld. Soldering was performed according to two methods: over the entire area of the mating surfaces and along the contour. After plastic deformation and heat treatment of the composite blanks, the weld on the stamping, pre-soldered along the contour of the mating surfaces, was destroyed after cooling. The welded joint on the stamping with soldering over the entire area remained inseparable.
