Abstract

The invention comprises a method and an apparatus for the manufacture of cylindrical hollow bodies by the shape welding process. This apparatus comprises a connection between a rotatably mounted supporting body which can be driven and a base body onto which the weld material is deposited. This connection is effected by elastically deformable elements and is capable of changing in the radial direction. Metal profiles which can be deformed elastically are fastened, in a manner permitting detachment, to the periphery of the supporting body, spaced at regular intervals. The base body is composed of a metal sheet or strip which is wrapped around the profiles and attached to them in a manner permitting detachment. Preferably the profiles extend over the length of the supporting body. The deformable metal profiles may be designed as cylindrical tubes, without any discontinuities or as half-tubes, angle-profiles, Z-profiles, or corrugated-sheet profiles.
