Abstract

This paper presents results obtained via experimental measurements of residual stresses in the cross sections of longitudinal welded pipes. The experiment is carried out over following pipe dimensions: Ø 139,7×4 mm, Ø 139,7×7,72 mm, Ø 219,1×5 mm, Ø 219,1×8 mm, Ø 244,5×8.94 mm, Ø 323.9×7,10 mm and Ø 323,9×10 mm. Residual stresses are measured with strain gages set upon the outside wall of the pipes. The results received from the gages show considering amount of stress captured in the pipe wall because of cold plastic formation process. Residual stresses for different pipe dimensions are in the range of 70 up to 270 MPa.

Keywords: residual stresses, strain; longitudinal welded pipes; cold plastic formation; high frequency welding
