Abstract
Welding in a water environment carries out a lot of problems, among which the most important could be the susceptibility of steel to cold cracking. There are many methods to prevent these cracks during welding in the air, which couldnt be use in wet welding conditions. For the reason, it is necessary to determine the susceptibility of steel to cold cracking. The paper presents experimental evaluation of the welda- bility of fine-grained high strength low alloy S460N steel wet welded by coated electrodes. From the results of Tekken tests it was found out that the investigated steel is char- acterized by the high susceptibility to cold cracking. It is necessary to look for a method that allows to overcome this problem.
