The quality of the bimetal produced by explosion welding is affected by the mechanical characteristics of flying plate material. For development of explosion welding modes, a study of the structure and mechanical properties of titanium alloy Grade 12 (TA10, flying plate) + carbon steel 16 Mn (09G2S) bimetal was conducted. The thickness of the titanium alloy plates was 5 and 6 mm, the mechanical properties, namely the relative elongation in as-delivered condition for these plates differed by 15 %. The results on tear and shear strength of titanium alloy-carbon steel bimetal are given. In the case of titanium alloy TA10 it is demonstrated that for plates with a lower relative elongation, the strength of the joint produced by explosion welding is lower. Bending test showed no delamination for two thicknesses of the titanium alloy. Also, for the two thicknesses of the titanium alloy, the joint zone has a microstructure characteristic for explosion welding. 8 Ref., 4 Tabl., 7 Fig.
