“…2 are presented the results of Tekken tests performed underwater, which were used for development of an equation for determining the minimum heat input value which protects against cold cracks forming [4]. [4] The equation is of the following form: The tests [17] on Implant specimens, performed in the conditions similar to those for Tekken test, showed that critical stresses were higher than yield point of the tested steel. It goes to show that the steel was crack-resistant, which is not consistent with the results given in [4].…”

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)

“…In the most cases underwater welding is used for joining carbon steels, low alloy steels, austenitic and duplex stainless steels [2,4,12]. Weldability of steel in water environment is governed by its cold or hot cracking tendency [28,29,27,30]. Susceptibility to cold cracking is main problem in welding of high strength low alloy steels (HSLA) (Fig.…”

The paper describes principles of underwater welding and recent trends in research works undertaken for enhance welding technology and properties of underwater welds. Department of Materials Technology and Welding at Gdansk University of Technology (GUT) has been involved in underwater welding research for over 25 years. Investigations include technology of underwater welding, and weld properties examinations. All tests have been performed with the use of self designed stands allow to perform welds in shallow depths as well as the depths up to 1000 m. The main investigation directions performed at the Department of Materials Technology and Welding are presented:Weldability of HSLA steel and factors influencing susceptibility to cold cracking of welded joints. The effects of wet welding conditions on diffusible hydrogen amount in the welds. The effects of heat input, underwater welding depths and composition of shielded gases on welds toughness.

The article describes the problems with weldability of high-strength steels in the aquatic environment. The tendency of steel S355J2G3 and S500M to form cold cracks when welded in wet welding conditions has been experimentally evaluated.It was found that the tested steels have a high propensity to cracking. An experiment has been proposed and tested to evaluate the usefulness of the tempering bead technique as a method of improving the weldability of high-strength steels under water in wet welding conditions.
