#CMT# #/CMT# Production of a round container base made from metal comprises deforming a non-processed edge of the base (3) using an inner roller and an outer roller forming an inwardly pointing bead and mechanically processing the bead of the base producing a bevel which forms a bead welding seam (9) with the welding edge of the container casing (2). #CMT# : #/CMT# An independent claim is also included for a container produced by the above process. #CMT#USE : #/CMT# Production of a round container base made from metal. #CMT#ADVANTAGE : #/CMT# A precise edge diameter of the welding edge is produced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-section through the finished container. 1 : Container 2 : Container casing 3 : Base 4 : V-shaped welding seam 9 : Bead welding seam #CMT#METALLURGY : #/CMT# Preferred Features: The inner collar of the welding edge of the container base has a wall thickness of 1-3 mm and an axial length of 8-12 mm.
