“…According to the most general classification, the underwater welding processes can be divided into dry and wet ones [1][2][3][4][5]. The dry methods consist in local isolation of welding area from surrounding water by means of special chambers in which atmospheric pressure (isobaric welding) or an elevated pressure resulting from welding depth (hyperbaric welding) is present.…”

“…A characteristic feature of the wet welding is direct underwater contact of diver-welder, electrode and base material. An intermediate variant between wet and dry welding is application of a local dry chamber (dry spot welding) [1][2][3]. Applicability of particular processes in underwater welding conditions is characterized in Tab.…”

Among wet welding methods, the manual metal arc welding is most often used, hence majority of steel weldability test results accessible in the subject-matter literature concern the above mentioned process [4][5][6][11][12][13][14][15][16][17][18][19][20].Transferring the welding process to water environment results first of all in increasing diffusible hydrogen content in deposited metal, as well as in increased cooling rate. Manual metal arc welding in wet conditions generates the diffusible hydrogen content in deposited metal, of the order of a few dozen ml/100g Fe, depending on a type of shielding and welding conditions [14,15]. The tests [15,16] performed with the use of rutile-shielded electrodes, the most often applied in such conditions, showed that hydrogen content in deposited metal did not depend on a wetting degree of the shielding, but heat input was the decisive factor (Fig. 1).POLISH MARITIME RESEARCH 2(78)

The present work was conducted to assess the weldability of duplex stainless steel in underwater conditions. Metal manual arc welding (MMA) with the use of coated electrodes was used in the investigations. Tekken weldability tests were performed underwater at 0.5 m depth and in the air. Nondestructive tests, metallographic examinations of welds, ferrite content assessment in microstructure and hardness test were performed. The good weldability at underwater conditions of duplex stainless with the use of MMA method was confirmed, however difficulties in stable arc burning were revealed.
