The article proposes a technology of repair of composite (i.e. obtained by welding and expanding) tube to tubesheet joints of heatexchanging apparatuses using friction welding operations devoid of heat treatment. The objective of the investigation was to determine the influence of using the proposed technology for repairing the composite joints made of 15Cr5Mo steel on the properties of the joint. Samples made by different technologies were tested for strength and tightness. The result of the study was the confirmation of compliance of the characteristics of the samples made by the proposed technology with the samples made by the currently widely used technology utilizes arc welding.
