Paton Electric Welding Institute popup.description2 Created models of processes heat and mass-transfer in melted pool, keyhole and plasma plume allow complex to describe thermal, electromagnetic, optical and magnet-hydrodynamic processes as in welding pool, and in ambient space as well, and can be used for research of mechanisms of interaction of laser beam with the processed metal and appearing ionized metallic vapor (vapor-plasma plume) with the purpose of increase of penetrate ability of laser methods of welding and achievement of effect of deep penetration. Technical advantages of the created models consist in possibility determination of mechanisms and ways of achievement of high penetrate ability of laser methods of welding which is absent in home and foreign analogues. It influences substantial character on speed of welding and on quality of the welds. The increases of penetrate ability of laser processes of welding will allow to increase the depth of penetration in 1.5-2 times without the substantial change of power of heating source. The laser methods of welding with deep penetration will find a wideuse on the enterprises of engineering, as an alternative to the electron-beam welding.
