The procurement of raw materials for the production plan is based on the technical parameters provided by the technical department, and a procurement plan is formulated. The business department purchases materials according to the plan. Before procurement, the supplier is first evaluated and selected, and the incoming materials are re inspected according to regulations. Unqualified materials shall not be stored or put into production. The three zones shall be clearly defined, and the distribution, collection, marking, transplantation, and substitution of materials shall be carried out in accordance with relevant regulations to ensure that the accounts, materials, and cards are consistent. The production process involves strict process requirements for cutting, machining, product testing, welding, flaw detection, marking, drilling, assembly, hydrostatic testing, furnace laying, painting, packaging, and other processes. Through the control links, control points, and hold points of the inspection system, the control points are controlled, and any problems found during the hold points must be stopped. The "three no let go" system is implemented to ensure that product manufacturing follows the "three press" and "three inspection" system, and quality issues are promptly reported. Non destructive testing shall be carried out based on the "commission form" of the surface inspection qualified workpiece. For the repair of defects exceeding the standard, the repair system shall be strictly implemented and retesting shall be carried out. In the various systems of the quality system, there are 34 control links, 55 control points, and 4 hold points. The key processes of each hold point and control point are in accordance with the system requirements, and various quality documents are clear and standardized. Approval and changes are made according to procedural regulations. Outsourcing and supply of external accessories shall be tested and implemented according to the system, and selected based on merit. The main pressure components shall be recorded on a one-to-one basis, with complete signatures and clear records for each process, achieving "two self controls" and "three satisfactions". On the basis of their respective qualifications, they shall consciously accept the supervision and inspection of the supervisory personnel, fulfill the procedures, and ensure that any non-conforming components are not transferred to the next process, so that product identification and traceability comply with the principle of uniqueness.
