Abstract
A process to form a substantially thick walled hollow bar by hot rolling an elongate member to form an internal hole, whereby the elongate member is formed around the internal hole and the outer edges of the elongate member are brought substantially into contact with each other or into close proximity to each other such that the outer edges form substantially longitudinal contact faces capable of being forced into very close or intimate contact with each other.
