Theory and technology of welding of dissimilar materials by high power fiber laser

Problem of welding of dissimilar materials often found in industry. Such joints are typical for parts of light constructions, ship and fuel apparatus, tanks, accumulators and so on. Best results for this case are obtained using laser welding, but process complexity complicates the experimental selection of process parameters. Solution is to use physically-adequate mathematic process-model, taking into account the difference in thermal properties of welded materials, diffusion and kinetics of phase transformations, defining formation of intermetallic phases.
