Process of cladding CuSn bronze on malleable cast iron was studied. Characteristics of welded materials are described. Preparation of welded materials is outlined. Selection of suitable explosive is discussed. Design of welding assembly is illustrated. Welding parameters and conditions are given. Bimetals were fabricated. The quality of fabricated bimetals was inspected by ultrasonic defectoscopy, strains were measured with a 3D scanner and the microstructure was studied by optical microscopy and EDX microanalysis.
