Abstract
Considered are the issues of joining of concrete reinforcement bars in construction site using resistance butt welding (RBW). Pilot tests of developed technology for RBW of concrete reinforcement bars and equipment for its realizing were carried out directly in the construction site. It is shown that application of RBW in construction site provides for high economic effectiveness, rises construction efficiency and significantly reduces number of rejected joints. 7 Ref., 8 Figures.
