Zhengzhou Erfeng Truss Display Equipment specializes in renting and building trusses, stages, wedding stands, lighting, sound, arches, air columns, exhibition layouts, truss construction, spotlight installation, and carefully crafted banners, photos, inkjet paintings, boards, and display racks. First-class construction team, ultra-low cooperation price, looking forward to your call. It is safer to build a booth with a large span by thickening the truss and diagonal ties. It is reported that graduates of BISU's convention and exhibition major have worked in the China Council for the Promotion of International Trade, the National Convention Center, Koelnmesse, Reed Exhibitions, and the convention and exhibition business departments of China Travel Service Group, China National Travel Service Group, and CYTS Group, becoming a new force in China's convention and exhibition industry. . Erfeng Stage Truss takes some common truss forms as examples to understand the specific situation. The welding speed of aluminum stage trusses is also the main factor that determines the deformation. The low heat input speed of welding trusses and glass curtain wall aluminum will cause the price of larger trusses to expand, and the cooling shrinkage in the process is also opposite. The bigger. Insufficient heat input to the octagonal prism can lead to poor welding, producing defects such as lack of penetration and unfusion. Preheated welding before can reduce the deformation degree and crack tendency of square tube truss products, and increase the truss welding speed. During the cooling process of the truss welded structure, excessive restrictions may also cause welding cracks. The shape and welding amount of the octagonal prism welding groove are the main factors affecting the deformation. The welding deformation is usually much smaller than that of many welded grooves. During the solidification process of aluminum alloy trusses and open-frame glass curtain walls, the volume of the trusses in the molten state is approximately 100%. The shrinkage stress generated during this process may cause deformation of the welded joints. Welding heat input near the welding area of the glass curtain wall will cause the metal to expand, the heat source is false, and the metal will shrink as it cools. Coupled with the shrinkage of the molten metal during the cooling process, it can cause tensile stress and crack sensitivity in the price of the trusses at the weld. increase. Aluminum alloy trusses are also called trusses and frames. They are generally made of aluminum materials that have been cut, processed, welded, polished, spray painted, etc. They are widely used in performances and exhibitions, event celebrations, background layouts, lighting and sound hanging trusses. price and other systems.
