Dissimilar underwater wet welding of HSLA steels [PDF]
The International Journal of Advanced Manufacturing Technology, 2020 AbstractThe high-strength low-alloy S460ML and S460N steels were chosen for underwater wet welding of dissimilar T-joints using covered electrodes. For improving the quality of joints, the temper bead welding (TBW) method was used. The application of TBW in pad welding conditions has been investigated earlier but the possibility of usage of this ...

Post Underwater Wet Welding Heat Treatment by Underwater Wet Induction Heating
Welding Journal, 2021 Wet welding procedures of Class A structural ship steels frequently fail to comply with the American Welding Society (AWS) D3.6M, Underwater Welding Code, in the maximum hardness criterion for the heat-affected zone (HAZ). The maximum hardness accepted in a welded joint is 325 HV for higher-strength steel (yield strength > 350 MPa).

Temper Bead Welding of S460N Steel in Wet Welding Conditions [PDF]
Advances in Materials Science, 2018 Abstract Wet welding is the most common method of welding in water environment. It is most often used for repairing of underwater parts of offshore structures. However, the water as a welding environment causes an increase of susceptibility of steels to cold cracking.
