Abstract
The present work was to determine the residual stresses developed on the surface of welded plate in saline water using X-ray diffraction method.
Weld beads were deposited on carbon manganese steel under a 200 mm depth of both fresh and saline water using coated rutile electrodes type E 7012. Open air welds were also deposited for the purpose of comparison.
The residual stress levels were measured and compared for welds made under fresh and saline water with those obtained for normal open air welds made under the same set of welding parameters.
It was found that the maximum sum of the surface stresses in fresh and saline water welds were about 81% and 77% of the maximum sum of surface stresses that developed in the open air welds, respectively.
