520  ‎$a‎High-power CO2 lasers are used extensively in various industrial applications. In most cases they form part of open-beam equipment and have a power of several kilowatts, and are thus designated as Safety Class 4 systems. In addition to the invisible i.r. laser beam, u.v. radiation and visible light may be emitted. In the present work a power meter controlled by microprocessor and a spectroradiometer measured the scattered or reflected laser radiation. In addition, concentration levels of welding and cutting fumes and of pyrolysis products of plastics were determined during various laser processes. Finally, a safety analysis was performed to compare the hazards of laser welding with those of conventional welding methods
