Paton Electric Welding Institute of the National Academy of Sciences of Ukraine popup.description2 During the work found that to improve the geometry obtained seams, eliminating the threat of formation of internal pores and cracks to apply the following pulse modulation of laser and arc consumable electrode that coincide or are multiples of the frequency of oscillation weld pool. It is appropriate width modulation only laser or exclusively arc consumable electrode. To eliminate the characteristic defects hybrid welding of carbon steels as sagging seams, undercuts formation and burnout are encouraged to perform design edges that stykuyut from dulling and conduct a preliminary laser welding seam root, then fill in the development of hybrid method. To improve the mechanical properties of welded joints of carbon steels offer select mode hybrid welding so as to create the necessary conditions for preserving the structural components that are favorable to increase resilience and do not worsen Tensile strength. As shown in the previous part of the work in order to achieve these conditions, welding steel thickness 5...7 mm should be made to the energy per unit length 950 ... 1050 J / mm, thickness 7...9 mm - 1000 ... 1100 J / mm , 9...12 mm - 1100 ... 1350 J / mm.
