METHOD OF WELDED JOINTS TREATMENT AND MILL CUTTER FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2018 - IPC B23K37/00 B23C3/12 B23C5/04 

FIELD: metallurgy.

SUBSTANCE: welded joint is exposed to a rotating cylindrical mill cutter, having at its lower end a conical projection with base diameter d and the angle between the base and the cone side surface ϕ=arc Sin [(0.1-0.8)/d] wherein the mill cutter is set at an angle ϕ₁, equal to the angle ϕ, so that the lower point of the mill cutter end contacts the base metal followed by moving the mill cutter at the angle forward along the weld seam.

EFFECT: use of the invention makes it possible to treat welded joints with plastic deformation, that increases their simultaneously removed by the core to the level of the base metal.
