description: Theme of qualification work: Â«Non-destructive testing (NDT) of defects and welding stresses after underwater weldingÂ». This work considers the possibility of estimating residual welding stresses using magnetic anisotropy and X-ray diffractometric methods. Using the magnetic anisotropy method, the degree of inhomogeneity of residual stresses in samples with welding performed under water was found. With the help of an X-ray diffractometer, the magnitude of the detected residual welding stresses was compared.Radiographic inspection revealed surface and subsurface defects after welding. Detection of defects is important for the quality of welding joints. Tasks of the final qualification work: â analysis of scientific and technical information on underwater welding technologies; â analysis of methods of non-destructive testing (NDT) of welded joints; â analysis of regulatory documents for NDT welded joints; â investigation of defects and residual welding stresses during underwaterwelding; â development of the NDT program and methodology and determination of residual welding stresses of welded joints after underwater wet welding.
