 The object of research - the laws of gas-dynamic processes in laser welding of steels and alloys and their use to develop methods for controlling the properties of welded joints in laser welding of steels and alloys.As a result of the work it was found that when creating a rotating protective gas flow using an axisymmetric slit flow channel, conditions are created that can potentially positively affect the deflection of the plasma torch thereby increasing the penetration depth by eliminating the effect of plasma torch shielding. The powerful centrifugal component of the rotational flow can potentially also prevent the particles of the vapor-plasma torch and drops of liquid metal from falling on the surface of the focusing lens.The scientific results obtained during the research were used in the development of technological recommendations and provisions of the established methodology for managing
