Study into the Use of Alternative Technologies in the Manufacture of Rolled and Welded Tube-to-Tube Sheet Joints

Abstract

An alternative technology for the manufacture of rolled and welded tube-to-tube sheet joints using friction welding without heat treatment is proposed. The aim of the study was to evaluate the operational characteristics of samples simulating rolled and welded tube-to-tube sheet joints using alternative technology, as well as their comparison with samples made using the basic technology involving heat treatment. The test results confirmed the conformity of samples made using the alternative technology in terms of density and strength, as well as in the predicted reliable operation resource for samples made according to the basic technology.
