ABSTRACT:
The present invention relates to a method for manufacturing shells, wherein a belt is attached to the outer surface of the shell by friction welding. The method is particularly favorable for welding bands to thin-walled shells. In the method, prior to the welding process, the shell is hardened and/or tempered for optimizing its properties during use and, after hardening and/or tempering, the shell receives the belt by friction welding, during which the temperature of the shell is kept at a level which does not reduce the qualities of the shell to a substantial degree.
