Forthcoming from the Gordon and Breach Publishing Group: Laser-Arc Processes and their Applications in Welding and Material Treatment Peter Seyffarth Welding Research and Training Institute Rostock Germany Igor V. Krivtsun E.O. Paton Electric Welding Institute National Academy of Sciences of the Ukraine Kiev, Ukraine This volume presents a comprehensive and timely overview of laser-arc processes for material joining and treatment, which is a current and developing research area. The authors review existing methods for combined welding and associated processes and describe the theoretical investigations of the stationary combined discharge induced by focused laser radiation of CW CO2 - laser affecting the DC arc plasma. The volume also details the main principles of integrated plasma torches together with their applications in the joining and treatment of materials. Contents include: Chapter 1. Development of the Combined Laser-Arc Processes for Joining and Treatment of Materials (Survey) Effects of the simultaneous action of the laser beam and the electric arc on a workpiece; Schemes for practical realisation of laser-arc welding, cutting and surface treatment; Energy characteristics and technological potentialities of the combined laser-arc heat source; Mutual effects of the laser beam and the electric arc in combined processes Chapter 2. Laser Beam-Arc Plasma Interaction and the Combined Discharge Physical basis of laser beam and arc plasma interaction and mathematical model of the laser-arc discharge; Thermal, transport and optical properties of the combined discharge plasma; Analysis of the results of the laser-arc discharge simulation Chapter 3. Integrated Plasma Torches for Laser-Arc Processes Methods and devices for practical realisation of the combined discharge; Theoretical basis and calculation technique of the laser-arc plasma torches; Simulation of the integrated plasma torch for laser-plasma powder deposition Chapter 4.
