The paper present the evaluate the bending load capacity of a composite beam made of titanium Grade 2 and titanium alloy Grade 5. The beam was made using the Resistance Spot Welding technology. All elements of the construction were cut from sheet thickness of 0.8 mm. Web and flanges of beams made from titanium alloy Grade 5 sheet. Flanges were joined with the web using the cold-formed brackets made of titanium Grade 2. The welding parameters of RSW were selected on the basic of strength tests and analysis of the microstructure. Grade 2 Grade 5 and Grade 5-Grade 5 sheets titanium were combined. Optimized parameters were also used to analyze joints with two welds: arranged parallel and perpendicular to the shear direction. The load capacity of joints, plastic strain distribution and the method of destruction was assessed. Results from the experimental research of joints with single welds are compared with the results of the numerical analysis. The numerical analysis was carried out using the ADINA system based on the Finite Element Method. Static tensile test was carried for titanium Grade 2 and Grade 5 with a thickness of 0.8 mm to numerical analysis. The composite beam made at paper was subjected to three-point bending.
