Abstract
The paper presents the data of fatigue testing and analysis of susceptibility of the metal of cruciform welded samples of low-alloyed steel to the impact of a corroding medium under the conditions simulating the service of off-shore water development works on the continental shelf. It is shown that local explosion treatment of the joints allows a noticeable improvement of their resistance to corrosion-mechanical failures. The results of fatigue testing in air allow forecasting the joints behaviour in sea water at alternating loading.
