Zuev Institute of Atmospheric Optics SB RAS (IAO SB RAS), 1 Academician Zuev square, Tomsk, 634055, Russian Federation Abstract In this work, a technique is applied that is used in the study of fast processes in arc welding with a consumable electrode. The main problems of video capturing are discussed. It is offered ways for used equipment improvement. One of the ways is the increase of laser coherent radiation intensity. The second one is the development and application of special software that facilitate noise reduction and statistical processing of recorded data, as well as visualization. New obtained results have shown that the offered ways have allowed improving the quality of video flow and the power characteristics of welding process.
