Welded Ball Node
MATERIAL OF WELDED BALL NODE The material of Bolt Ball Node uses 2 round steel plates (Q235 or Q355) are welded after hot or cold-pressed into two hemispheres. CHARACTERISTIC OF WELDED BALL NODE The advantages of the welded ball node are clear force transmission, simple structure, beautiful shape, convenient connection and adaptability in the space frame construction. This node is suitable for connecting round steel pipe , as long as the steel pipe cutting surface perpendicular to the axis of the steel rod can be in the hollow sphere on the natural alignment without eccentricity. As the sphere is not directional, it can be connected with the rod in any direction, and its advantages are more prominent when there are more converging rods. Once, it is highly adaptable and can be used in all forms of netting structures. The disadvantages of the welded ball node are: a larger amount of steel, Node steel consumption accounts for 20%-25% of the total steel consumption of the grid.; s
