The work presents results of explosively welded steel-titanium bimetal fatigue tests, as well as the native and clad-on materials. The tests were applied to specimens made of bimetal constituting fusion of S355J2 steel with SB 265 G1 titanium, where the latter was the material being clad-on during plating process. Both the material prior to plating (the titanium) and following plating was tested, as well as prior to and following the heat treatment process. The tests result in fatigue life of specimens made of native material, acquired from the plater, being lower than that of the steel-titanium bimetal specimens fatigue life, while the fatigue life of SB 265 G1 titanium does not change significantly in result of plating. Furthermore, the state of stress in the plater native layer following welding (compressive stress), positively influences its fatigue life, this effect being insignificantly reduced by heat treatment.
