In the process of grid processing, quality control is the key to ensuring the safety, stability, and efficient use of the grid structure. It is necessary to strictly control all aspects from raw materials, processing, inspection, packaging, transportation, and storage.
Strict selection of raw materials to establish a solid quality foundation: In the procurement process, high-quality suppliers are carefully selected to ensure that steel and other raw materials meet the mechanical properties and chemical composition standards specified in the design. Each batch of materials must be accompanied by complete quality certification documents. After the materials enter the site, strict inspection should be carried out immediately. It is necessary to carefully examine the appearance, check for obvious defects such as cracks, rust, and deformation, and accurately measure the dimensions to verify whether the specifications meet the standards. At the same time, mechanical performance tests and chemical analysis should be conducted according to the established frequency to ensure quality first and resolutely prevent unqualified materials from entering the processing stage.
Strictly control processing and adhere to process standards: When cutting and cutting materials, cutting-edge equipment and processes such as CNC flame cutting and plasma cutting are used to accurately control the cutting size accuracy, maintain the perpendicularity and roughness of the cutting surface within the ideal range, and minimize cutting deformation. In the welding process, welding personnel must hold certificates and operate strictly according to the parameters determined by the welding process evaluation. The welding current, voltage, and speed must be precisely controlled, and scientific welding sequences and methods must be adopted to minimize welding stress and deformation, and eliminate welding defects such as porosity, slag inclusion, and cracks. After welding is completed, timely conduct visual inspection and non-destructive testing of the weld seam to ensure that the weld quality is up to standard. For components such as rods and nodes, high-precision machining equipment is used to ensure that the machining dimensional accuracy and geometric tolerances meet the design requirements.
Comprehensive quality inspection and precise quality control: Multiple inspection processes are set up throughout the processing to monitor each link in real-time. Once quality problems are detected, they are immediately rectified and corrected. After the processing of the grid frame is completed, a comprehensive finished product inspection is carried out, covering items such as dimensional deviation inspection, appearance quality inspection, and weld quality review. Organize trial assembly, verify overall dimensions and installation accuracy, laying the foundation for smooth installation in the future.
Standardize packaging, transportation, and storage to safeguard the quality of finished products: Use packaging materials such as plastic film and grass rope to properly wrap the processed grid components to prevent damage caused by collisions or scratches during transportation. Choose appropriate transportation methods and tools according to the actual situation to ensure smooth transportation. The components of the grid should be stored in a dry and ventilated area to avoid moisture, rust, and deformation, and to fully protect the quality of the finished product.
