METHOD OF METALLIC PRODUCT MANUFACTURE, METALLIC PRODUCT, METHOD OF CONNECTION OF METALLIC PARTS, AND DESIGN WITH CONNECTION Russian patent published in 2008 - IPC B23P15/04 B23P6/00 B23H9/00 C23C24/00 B23K33/00 B22D29/00 C23C26/00 C21D9/50

Abstract RU 2325257 C2

FIELD: metallurgy.

SUBSTANCE: body of the product is formed. The area surrounding the defect is removed, including the defect that occurred on the processed product body surface during forming, making a recess in the processed surface. Deposits from the depositing tool (electrode) formed by pressing powder consisting of essentially of the product body metal are settled filling the recessed area. Processing is performed in an electrospark discharge machine.

EFFECT: eliminates thermal deformation at periphery of recessed area; increases metallic product manufacture quality.
