Through quality inspection, the failure rate of tungsten wire can be effectively reduced. The following are some specific strategies and methods:
- Comprehensive and strict inspection items
Microstructure analysis:
Use advanced equipment such as scanning electron microscope (SEM) to observe the grain structure and defects of tungsten wire to ensure the uniformity and integrity of the internal structure of tungsten wire.
Surface quality inspection:
Detect the surface finish and defects of tungsten wire, such as cracks, oxide layer, etc. Surface defects often affect the performance and service life of tungsten wire, so they must be strictly controlled.
Resistivity test:
Use the four-probe method and other methods to accurately measure the resistivity of tungsten wire and evaluate its conductive properties. The uniformity of resistivity is crucial to the performance of tungsten wire in electrical applications.
Mechanical property test:
Use a universal material testing machine to perform tensile tests and other tests to evaluate the mechanical properties of tungsten wire, including strength, toughness, etc. These properties directly affect the durability and reliability of tungsten wire during use.
- Advanced testing technology and equipment
Chemical analysis method:
Use X-ray fluorescence spectrometer (XRF) or energy dispersive X-ray spectrometer (EDX) to quantitatively analyze the chemical composition to ensure that the composition of tungsten wire meets the design requirements.
Eddy current flaw detection:
Use eddy current flaw detection equipment to perform non-destructive testing on tungsten wire to find internal cracks, inclusions and other defects. Eddy current flaw detection has the advantages of high efficiency and accuracy, and is suitable for quality control in large-scale production.
Metallurgical microscope observation:
Observe the metallographic structure of tungsten wire through metallographic microscope to provide support for microstructural analysis. The state of metallographic structure directly affects the performance and service life of tungsten wire.
- Strict quality control process
Raw material inspection:
Strictly inspect the purchased tungsten wire raw materials to ensure that the quality of raw materials meets production requirements.
Production process monitoring:
Set multiple quality inspection points in the production process, conduct real-time monitoring and sampling inspection of key processes, and timely discover and solve problems.
Finished product inspection:
Perform comprehensive inspection on the finished tungsten wire products, including appearance quality, dimensional accuracy, performance testing, etc., to ensure that the quality of finished products meets customer requirements and industry standards.
- Continuous improvement and feedback mechanism
Collect customer feedback:
Regularly collect customer feedback on the quality of tungsten wire to understand the performance and problems of the product in actual use.
Analyze the cause of failure:
Perform in-depth analysis of the faulty tungsten wire to find out the cause of the failure and potential quality problems.
Optimize production process:
According to the analysis results, optimize the production process and detection methods to improve the quality and reliability of tungsten wire.
Train operators:
Regularly conduct quality awareness and skills training for operators to improve their quality awareness and operating skills.
