Causes of deformation of aluminum alloy trusses

The aluminum alloy truss itself is a large force-bearing metal structure. This big guy has experienced countless castings and weldings before forming, and there will be welds after each weld. These welds are not just scattered on the slat. At the nodes, some welds are located elsewhere on the stage rack.For example, the middle of the weld at the bottom, the triangle or many corners of the aluminum alloy truss show uneven contrast, and perhaps the non-jointed points present a weld seam. With the effect of residual stress remaining in the weld on a very rigid aluminum alloy truss, in order to achieve uniform stress, the aluminum alloy truss is deformed.

Manufacturing elements of square tube folding truss

This kind of truss is made of ф22MM round steel pipe. Some articulated plans are used for connection. Each truss can be folded into a sheet for transportation / storage. The two ends of the truss are designed with spring heads. The truss and truss can be connected by hexagonal wires, and the local requirements at the corners are connected and fixed. The cross-section size of the circular tube folded truss after opening is 22 * 22CM, and the cross-section size after folding is 46 * 3CM. The maximum span can reach 10 meters. The center does not need to support columns.
