Research on the Welding Deformation Control of the Roof Beam Structure of Hydraulic Support for Coal Mines
Taking the welding deformation phenomenon of the roof beam structure of ZY8640/25.5/55 hydraulic support as the research object,the welding deformation of the roof beam structure is introduced on the basis of a brief introduction to the main structure and dimensions of the hydraulic support.The TANDEM double wire welding process for the roof beam structure is proposed,and the welding process parameters are designed in detail.Through the welding test,it is found that the maximum value of deformation between adjacent main reinforcement plates is 3.83 mm,which meets the basic requirement that the maximum deformation does not exceed 4 mm.So the proposed welding process is effective and achieves the effect of controlling the welding deformation of the top beam structure.
