Ponomarev K. E., Strelnikov I. V., Antonov A. A. — Results of the application of vibration treatment of AMg6 alloy joints in consumable and non-consumable electrode welding
The article considers examples of the practical implementation of vibration treatment carried out together with different methods of arc welding of AMg6 aluminum alloy: gas tungsten arc welding and semi-automatic welding. Based on the criteria of residual stresses and residual deformations, a comparative analysis of specimens obtained by these welding methods with and without the use of accompanying vibration treatment is carried out.

The presented work is devoted to the assessment of the influence of beam deflection in electron beam welding on the degree of weld metal penetration and, as a consequence, on the properties of welded dissimilar materials, which opens up wider opportunities for controlling the composition of the weld metal during welding. The paper presents the relationship between beam deflection and the properties of the resulting welded joints. It is shown that the use of numerical models makes it possible to quantitatively predict the parameters of beam deflection in electron beam welding of dissimilar steels.
