Laser-Arc Processes and Their Applications in Welding and Material Treatment 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 theoretical investigations of the stationary combined discharge induced by focused laser radiation of CW CO2-lasers 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.
