Abstract

A large cylindrical structural element is manufactured by welding together a pair of thick-walled cylindrical components at their ends by applying between the cylindrical components at least one buffer layer of weld material, the buffer layer being applied by a welding electrode held with its axis maintained at an angle to the plane of abutting surfaces of the components with the at least one buffer layer being applied in the form of weld beads which overlap and subsequently applying an assembly weld seam to join the components together.
