Abstract

Abstract: In order to ensure the product quality of AWF to guarantee the safety of the welding workers' eyes, the measuring mechanism and methods for the transmittance uniformity and angle dependence of the AWF were analyzed. An innovative AWF measuring system including scanning controller based on 4-dimensional motion platform were developed, and the experiments and result analyses for transmittance uniformity and angle dependence of the AWF were completed. The results show that transmittance uniformity and angle dependence are important technical indexes for evaluating the quality of AWF products as both of them can indicate the characteristics of AWF, and that the experimental results obtained by the measuring system are in good agreement with the nominal data of products. The results also show that the proposed measuring system can be widely used as standard testing instruments to detect the transmittance uniformity and angle dependence of AWF.

Key words: automatic welding filter (AWF), transmittance uniformity, angle dependence, 4-D automatic scanning platform, measuring system
