Quality Control and Inspection of Molybdenum Rod Connection

In the quality control and inspection of molybdenum rod connection, a series of rigorous steps and standards must be followed to ensure the quality and reliability of the connection. Here is a clear overview of the quality control and inspection process, incorporating relevant figures and information:

1. Incoming Material Inspection

  • Material Specification: Ensure that the molybdenum rod connection material meets the prescribed specifications and dimensional requirements.
  • Purity Requirements: For high-purity molybdenum rods, the purity may be required to reach 99.9% or higher to ensure electrical conductivity and corrosion resistance.
  • ROHS Compliance: Ensure that the material meets environmental protection requirements, such as ROHS standards, which limit the use of hazardous substances.

2. Connection Process Control

  • Welding Quality: For welded molybdenum rod connections, control the welding temperature, time, and pressure to ensure welding strength meets or exceeds specified standards (e.g., ≥30N).
  • Dimensional Inspection: Use micrometers, vernier calipers, and other tools to inspect the dimensions of the connected rods, ensuring they fall within the predetermined tolerance range.

3. In-process Inspection

  • Warehouse Management: Ensure that the connected components are managed according to specified quantities and specifications during storage, following the first-in, first-out principle.
  • Initial Product Inspection: Perform a comprehensive inspection on the first product produced to ensure it meets quality standards.
  • Product Inspection: Conduct regular inspections during the production process to ensure the consistency and stability of product quality.

4. Final Inspection

  • Visual Inspection: Check the surface of the connected components for flatness, smoothness, and the absence of cracks, burrs, and other defects.
  • Mechanical Performance Testing: If required, conduct mechanical performance testing such as tensile strength and bending properties to ensure the connected components possess sufficient mechanical properties.
  • Packaging and Shipment Inspection: Ensure that the product packaging is intact, with no missing or insufficient items, and meets shipment requirements.

5. Quality Control System

  • Establish a Comprehensive Quality Control System: This includes incoming material inspection, process control, in-process inspection, and final inspection to ensure comprehensive control of product quality.
  • Quality Record Management: Record and manage inspection results for easy traceability and analysis of quality issues.
  • Continuous Improvement: Continuously improve the production process and quality control system based on inspection results and customer feedback to enhance product quality and customer satisfaction.

6. Considerations

  • Safe Operation: Follow safety operating procedures during production and inspection to ensure the safety of personnel and equipment.
  • Equipment Maintenance: Regularly maintain and service production and inspection equipment to ensure their normal operation and accuracy.

The above is an overview of the quality control and inspection process for molybdenum rod connections. Specific processes may vary depending on product specifications, customer requirements, and production conditions. Adjustments and improvements may be made based on actual conditions.
