Paper Abstract

To optimize the welding processes and quality of a fixed connection needs to study of the melting and transfer of electrode metal into the weld pool. The paper discusses the results of studies of high speed processes of heat and mass transfer during arc welding with consumable electrodes. The imaging of such processes is difficult due to the presence of powerful light radiation from a welding arc. Its glow makes it practically impossible to obtain a satisfactory image using “simple” high-speed video recording methods. Our experimental researching has shown that the most effective method to improve the image quality of the studied object is the laser imaging method. It allows to significantly reduce the negative effects of background radiation. In the course of the research, the opportunity of using the CuBr laser with the narrow-band filters to image the observed object was shown.
