First, the importance of power battery welding quality.
Power battery is an important part of electric vehicles, and its welding quality is directly related to the safety performance and reliability of the battery. If the welding quality is not up to standard, it may lead to safety problems such as short circuit and thermal runaway inside the battery, posing a threat to the life and property safety of consumers. Therefore, it is crucial to inspect the welding quality of power batteries.
1.Non-destructive: X-ray non-destructive testing will not cause any damage to the detected object, which can ensure the integrity and performance of the detected object.
2.High efficiency: X-ray non-destructive testing can complete large-area detection in a short time, which improves the detection efficiency.
3.Accuracy: X-ray non-destructive testing can accurately detect defects and problems inside the inspected object, providing a reliable basis for subsequent improvement and optimization.
1.Welding defect detection: X-ray nondestructive testing can detect various defects generated in the welding process of power batteries, such as porosity, inclusions, unfused, etc. The presence of these defects can have a serious impact on the quality of the weld and even lead to weld failure. Through X-ray damage-free detection, these problems can be found and solved in time, and the welding quality and efficiency can be improved.
2.Weld quality assessment: X-ray non-damage inspection can evaluate the weld quality of the power battery, including the geometry of the weld, the continuity and integrity of the weld. Through the evaluation of weld quality, the advantages and disadvantages of the welding process and the reliability of the welding quality can be judged, which provides a useful reference for subsequent production and research and development.
3.Battery structure analysis: X-ray non-destructive testing can also analyze the structure of the power battery, including the material composition and structural arrangement inside the battery. Through the analysis of the battery structure, we can understand the working principle and performance characteristics of the battery, and provide a basis for the optimization and improvement of the battery.
