By optical metallography and analytical electron microscopy study of structural-phase changes in the resulting welds. It was established that the microstructure of weld metal characterized by a fairly uniform distribution of structural components and has a dendritic structure with the direction of the dendrites, corresponding to the temperature gradient during crystallization. The microhardness increases from the fusion line to the center of the weld metal at 10 ... 15%. When conducting mechanical tests revealed that the proposed technology allows welds to the value of ultimate tensile strength equal to 1,0 ... 0.8 of this setting the basic material, increasing the gap between the samples welded to 0,5 thickness welded edges. Forecast assumptions about the development of the object of research - the use of the results obtained in various industries to develop radically new technologies compound the fine details of a large range of materials using laser welding with filler material feed in powder form.
