Комплекс для исследования процессов дуговой сварки

The work presents the results of development and manufacture of a unique research complex for investigation of fast processes of heat-mass transfer in consumable electrode arc welding. Advantages of the developed complex over the traditionally applied ones using film and video cameras with shadow principle of registration of heat and mass transfer characteristics are shown. Fast processes were studied with application of high-speed video recording with illumination of the arc gap by Cu-Br laser beam, improving visualization of the studied object — the process of melting and transfer of each drop of molten metal under the conditions of intensive light of the electric arc. The paper contains explanatory diagrams, control algorithms, video frames of a separate welding microcycle, examples of oscillogram recording and graphical representations of changes in their quantitative values. 13 Ref., 1 Tabl., 14 Fig. [ABSTRACT FROM AUTHOR]
