Space frame processing refers to the process of cutting, welding, and assembling steel according to specific requirements to produce various types of space frame products. Space frames are widely used in fields such as buildings, bridges, factories, ships, and mechanical equipment, playing an important role in support and load-bearing. To ensure the quality of the space frame after processing, quality acceptance must be carried out. SAFS Steel Structure Space Frame Company will introduce the quality acceptance procedures and acceptance standards after space frame processing.

Quality acceptance procedures after space frame processing The quality acceptance after space frame processing is a systematic work, mainly including the following steps:
- Acceptance preparation: Develop a space frame processing quality acceptance plan, clarify the content, requirements, and methods of quality acceptance. Determine the responsible personnel and acceptance time for quality acceptance.
- Acceptance basis: Based on relevant national standards, industry standards, and technical specifications, formulate the quality acceptance standards and requirements for space frame processing. Ensure that the space frame after processing meets the specified technical requirements and quality standards.
- Preparation before acceptance: Carry out appearance inspection and size measurement on the space frame after processing, check its compliance with design drawings and technical documents. Confirm whether the basic geometric parameters and dimensional accuracy of the space frame processing meet the requirements.
- Acceptance process: Inspect the welding joints, welds, connection nodes, etc. of the space frame, and determine whether the welding quality is qualified. Carry out corrosion protection inspection on the surface of the space frame, and confirm whether the quality of surface treatment meets the requirements.
- Acceptance result evaluation: According to the actual situation of the space frame and the acceptance standards, evaluate whether the quality of the space frame processing is qualified. At the same time, rectify and repair the unqualified parts as needed.
- Acceptance report preparation: Prepare an acceptance report based on the quality acceptance results of the space frame. The report content includes basic information of the space frame, quality acceptance results, existing problems, and improvement measures.
- Post-acceptance processing: According to the results and requirements of the acceptance report, timely organize and archive the relevant documents and materials of space frame processing. Arrange transportation and installation work for the qualified space frame.

Quality acceptance standards for space frame processing The quality acceptance standard for space frame processing is an important basis for ensuring the quality of space frame processing. The following are common quality acceptance standards for space frame processing:
- Appearance quality: The surface of the space frame should be flat and clean, without obvious deformation, cracks, depressions, and damage. The defects of the welding joint should meet the requirements of relevant standards.
- Dimensional accuracy: The geometric parameters, dimensional accuracy, and dimensional deviation of the space frame should meet the design requirements and the provisions of relevant standards.
- Welding quality: The welding joint should meet the design requirements and the provisions of relevant standards. Welding defects such as porosity, cracks, slag inclusion, and incomplete penetration in the weld should meet the requirements of relevant standards.
- Material quality: The steel used in the space frame should meet the requirements of relevant standards. The mechanical properties, chemical composition, and physical properties of the material should meet the design requirements and the provisions of relevant standards.
- Surface treatment and anti-corrosion measures: The surface treatment and anti-corrosion measures of the space frame should meet the design requirements and the provisions of relevant standards. The thickness and quality of the anti-corrosion coating should meet the requirements of relevant standards.
- Connection strength: The connection node of the space frame should have sufficient strength and stability. The fasteners of the connection should meet the design requirements and the provisions of relevant standards.
- Functional performance: The space frame should have good performance and reliable bearing capacity. The experience should be consistent with the required goals. The above are common quality acceptance standards for space frame processing. The specific standards and requirements can be refined and improved according to the specific space frame processing project and requirements.
In summary, the quality acceptance after space frame processing is an important link to ensure the quality of space frame processing. By strictly following the quality acceptance procedures for acceptance, and based on the corresponding quality acceptance standards for the appearance, size, welding, materials, anti-corrosion treatment, etc. of the space frame, the qualified nature of the space frame processing quality can be ensured. Only a qualified space frame can meet the needs of related projects and ensure the safety and reliability of the project.
