Research on Welding Deformation Control Technology of Tower Crane Standard Section
As a key truss structure in tower cranes,standard sections can cause local expansion and deformation of parts during welding due to uneven heating and cooling,which seriously affects the stability and safety of the crane.To solve this problem,an optimized standard section welding deformation control technology has been proposed.By adjusting the welding sequence of the main chord,the number and size of welds on the belly member and connecting plate are reasonably arranged when designing the shape and size of the welding joint.Use symmetrical welding method to weld welded parts with uniform and symmetrical cross-sectional shape and weld seam arrangement.Through the optimization of the above technologies,the welding deformation problem of the standard section has been well controlled,which not only improves the accuracy of the standard section,but also enhances the construction efficiency and quality.
