Dear users, before using the iFlaw - 80 Ultrasonic Flaw Detector, please strictly follow the following professional operation procedures to ensure accurate flaw - detection results and stable operation of the equipment by Mikrosize Equipment Supplier. I. Pre - flaw - detection Preparation (1) Equipment Inspection Before starting the flaw detector, a comprehensive inspection of the equipment should be carried out using professional tools. Use a magnifying glass to check whether the outer shell of the equipment has any deformation, damage, or cracks to ensure good protective performance. Professional testing equipment should be used to check the display screen to ensure that there are no dead pixels and the display is clear and stable. Tools such as a multimeter should be used to test the interfaces to ensure normal electrical connections, stable signal transmission, and that the probe connection parts are not loose and have good contact. If any abnormalities are found, stop the operation immediately and contact professional maintenance personnel. (2) Probe Selection and Installation Based on the material, shape, size of the workpiece, and the expected type of defects, select the probe accurately. For example, when detecting thin - plate materials, a high - frequency probe should be selected first to improve the detection resolution; for detecting thick - wall workpieces, a low - frequency probe should be selected to ensure the penetration ability of ultrasonic waves. When installing the probe, use special tools to clean the probe and the interface, remove impurities, and ensure a tight connection. After connection, use a fixing device to fix the probe and manually check its stability. (3) Parameter Setting According to the characteristics of the workpiece and theflaw - detection standards, accurately set parameters such as flaw - detection frequency, gain, sound velocity, and flaw - detection depth range on the operation interface. When setting parameters, strictly refer to the standard specifications and carefully check to ensure that the parameters are accurate and correct to guarantee reliable flaw - detection results. II. Flaw - detection Process (1) Workpiece Surface Treatment Clean and pretreat the surface of the workpiece to be tested, removing impurities such as oil stains, rust, and dust. For workpieces with a rough surface, they need to be polished until the surface roughness meets the flaw - detection requirements to ensure good coupling between the probe and the workpiece surface and reduce flaw - detection errors. (2) Flaw - detection Operation Place the flaw detector with the installed probe steadily on the surface of the workpiece to ensure close coupling between the probe and the workpiece. Start the flaw detector and keep the probe moving at a uniform speed within the specified range. Pay close attention to the data and waveforms on the display screen. Judge whether there are defects inside the workpiece and the situation of the defects according to the waveform characteristics. If abnormal waveforms are found, mark the position immediately. (3) Data Recording and Analysis During the flaw - detection process, record key data and waveforms in a timely manner. After the flaw - detection is completed, analyze the data based on the flaw - detection standards and experience, judge whether the workpiece is qualified, and accurately evaluate the severity of the defects and their impact on the performance of the workpiece. III. Post - flaw - detection Treatment (1) Equipment Cleaning and Maintenance After the flaw - detection is completed, use special cleaning agents and soft cloths to clean the flaw detector and the probe to remove surface impurities. Check whether each component of the equipment is loose or damaged and tighten or repair it in a timely manner. Regularly conduct a comprehensive maintenance of the equipment, including calibrating parameters and maintaining the battery, to ensure good equipment performance. (3) Writing of Flaw - detection Report Based on the flaw - detection data and analysis results, write a standardized flaw - detection report. The report should include information about the workpiece, flaw - detection time, method, parameters, results, and treatment suggestions, etc., to ensure accuracy, clarity, and completeness and provide a reliable basis for subsequent work. By strictly following the above - mentioned steps, the performance of the flaw detector can be fully utilized. If you encounter any problems during the operation, you can refer to the manual or contact professional technical support. |
