The article presents the test results of stress corrosion resistance of explosion welded steel‐aluminum elements. The tests were carried out by means of the slow strain rate test (10 −6 s −1 ) in air and artificial sea water. The following parameters were measured: tensile strength, time‐to‐failure and destructive energy. The tested explosion welded joints show susceptibility to degradation of properties in the corrosive environment. Galvanic corrosion is the main reason of degradation of the measured values. Another mechanism of explosion welded joints' destruction was found in air and artificial sea water. The tests of the explosion welded elements in the fast flow of sea water showed substantial galvanic corrosion.
