Laser welding Large Thickness Steels with High-Power Fibre-Optic and CO2 lasers The article presents the experimental data of the interaction of laser radiation with plasma physics that accompanies laser welding process. Data are given for CO2 and fibre-optic lasers. Some conditions under which the fusion process proceeds more efficiently are shown. Also action of laser intensity, welding speed, and metal brands on the efficiency of the welding process is considered. Some concrete examples of the nature of metal penetration, properties of welded joints are presented.

Creation of Laser-Plasma Technologies for Metallic Constructions Utilization The possibility of creation a pulsed mode coal-fired gas dynamic laser (GDL) by means of active medium ripple is considered. It is shown that detonation combustion fuel cycle leads to superior occupation of inversion population density. Construction of a laser mobile technology complex on the standard transport base is considered. The complex design for cutting metal constructions.This allows to implement both a high and medium power transportable GDJ version.
