Abstract
In this study, AH36 steel plates which are commonly used in the hull of ships and in the construction of tanks in marine industry, were butt welded underwater by using shielded metal arc welding method and E6013 (GeKaTec UW E6013) rutile electrodes. Welding operations were carried out by expert industrial divers at a depth of 4 meters in a real sea environment. The plates were first subjected to non-destructive testing tests in accordance with the requirements of the AWS D3.6 standard. Then, hardness, Charpy impact, bending and tensile tests were performed to determine the mechanical properties of the welded plates joined under water, and the results were interpreted together with the microstructural transformations that occurred in the weld area.
