Title
Workplace exposure during laser beam welding of metals with different suction concepts and room ventilation conditions
Abstract
The workplace exposure during welding of stainless CrNisteel and zinc coated steel with Nd:YAG- and C02-lasers was investigated in a closed work region. The suction concept was changed from global suction via the work table towards local with use of a suction hood or a specially designed nozzle at the laser head. Additionally, the ventilation conditions of the closed work region are changed. The differences of measured durst concentrations show the efficiency of each condition. The results will serve as recommendations for the users of laser processing systems in industry.
