Research papers devoted to development of laser-plasma processes during the last two decades are reviewed. It was found that the current directions of scientific research of the processes of laser-plasma welding are focused mainly on studying the peculiarities of joint impact of constricted arc plasma and laser radiation with wave length of 1.03 – 1.07 μm (first of all, fiber laser) on steels and alloys, as well as studying the physical fundamentals of manifestation of the synergic (hybrid) effect at such an impact and determination of the possibilities of its practical application. It was determined, in particular, that increase of the effectiveness of synergic effect manifestation is related to improvement of the plasma arc burning conditions in the zone of ionized vapour plume, which forms under the impact of focused laser radiation, as well as simplification of laser keyhole formation due to plasma arc pressure.
