FIELD: process engineering.
SUBSTANCE: invention relates to production of axially symmetric welded structures. Billets are machined to produce shell ring and posts to be assembled in welding and assembling appliance. Posts are welded along shell ring generating line and turned around central axis through preset magnitude, thermally treated and machined. Truncated cone is formed on post end face being welded. Welding of posts to shell ring inner surface is performed by contact relief welding with post locked at lower electrode and positioning it in welding and assembling appliance made from material not conducting electric current.
EFFECT: ease of manufacture, higher quality and reliability of welded joints.
