We have all seen the stage of various performances, and now the technology is more and more advanced. Stage trusses are used when building a stage. Stage trusses are lightweight, easy to carry and easy to install, so they can be seen in many performances. Do you know what problems should be paid attention to when welding stage trusses? Today, Beijing Truss Factory will answer your questions! First of all, the truss should be welded on all sides, which is safer than welding on both sides. Secondly, the choice of truss raw materials is also very important. The performance of iron truss is different from that of aluminum alloy truss, so it is not allowed to cut corners in the production process to ensure the safety factor of truss. Truss weld must be full and uniform, without missing welding and black welding. After the truss is welded, the surface should be polished, packed after professional chemical cleaning, and then warehousing or logistics should be selected. Truss processing should be standardized, and there should be professional truss positioning platform abrasives, with accurate hole location, convenient installation and disassembly, and beautiful truss construction effect. In fact, before building the stage, it is necessary to determine the truss environment: it mainly includes the length of the stage, the length of the truss and the length of the stage as much as possible, and the height of the background plate, which is very important.

As long as the field measurement is carried out, the picture of the background plate can be accurately designed and the size of the truss frame can be confirmed. Only in this way can we ensure that the stage we build will be solid and reliable! Only when the accuracy of the equipment meets the requirements of the technical specifications of the drawings can spot welding be carried out. When the weld needs preheating, it must be preheated to the specified temperature before tack welding can be carried out. If there are cracks in tack welding, tack welding can be carried out again after analyzing the reasons. When welding in the assembly stage, the energy and the temperature of the highest floor must be strictly controlled, and the base metal on the working face is not allowed to be damaged at will. When multi-layer and multi-pass manual welding, the welded joints should be staggered.
