Industrial CT for Welding Inspection

​Industrial CT Inspection: Uncovering NDT Black Technology for Welding Quality

In the field of precision manufacturing, weld quality is directly related to product safety and reliability. Traditional inspection means such as visual inspection, ultrasonic flaw detection or X-ray inspection, although widely used, but there is a lack of precision, low efficiency or destructive detection limitations. And withIndustrial CT equipmentinnovation.Industrial CT InspectionTechnology is "non-destructive, three-dimensional, high-precision" advantage, become the welding quality control of the "eyes of gold".

I. How does industrial CT inspection empower welding quality control?

​Industrial CT (industrial computed tomography)Through the high-energy X-ray penetration of the workpiece, combined with three-dimensional reconstruction algorithms, the welding part can be "layer by layer scanning", generating high-resolution three-dimensional images. This technology not only clearly shows the cracks, pores, inclusions and other defects inside the weld, but also accurately quantifies the size, location and distribution of the defects, providing data support for the optimization of the welding process.

​Typical application scenarios include::

1. ​aerospace: Defect detection of precision welds on turbine blades and spacecraft;
2. ​new energy vehicle: Power cell module welding, quality assessment of body structural component joints;
3. ​Energy equipment: Welding integrity analysis of oil pipelines, nuclear reactor pressure vessels;
4. ​electric equipment: 3D non-destructive inspection of micro sensors, chip package solder joints.

Second, the three core advantages of industrial CT equipment

1. ​Non-destructive testing to reduce costs and increase efficiency​
   Conventional sectioning requires destruction of the sample, whereasIndustrial CT equipmentIt can realize the whole life cycle quality monitoring without damaging the workpiece, which is especially suitable for the inspection needs of high-value or small batch customized products, and significantly reduces the cost of enterprises.
2. ​Three-dimensional imaging for precise positioning​
   Industrial CT technology generates three-dimensional body data models that support arbitrary angle profiling and defect volume calculations. For example, in multi-layer, multi-pass welding, the equipment can accurately identify tiny air holes buried deep inside (with micron resolution), avoiding the risk of missed inspections.
3. ​Intelligent analytics, data-driven​
   Combined with AI algorithms.Industrial CT InspectionThe system automatically identifies defect types, assesses risk levels, and generates visualization reports. This data-based approach helps companies to establish a welding quality database, providing a scientific basis for process optimization.

Third, how to choose the right industrial CT equipment?

Enterprises are shopping forIndustrial CT equipmentThe following factors need to be taken into consideration:

• ​Testing needs: Select the appropriate X-ray source according to the size of the workpiece (e.g., large structural parts requiring high penetration CT) and the density of the material (e.g., the difference in penetration ability between aluminum alloys and titanium alloys);
• ​Resolution Requirements: Micron-level detection requires a nanofocused radiation source with a high-precision detector;
• ​degree of automationFor batch inspection scenarios, a robot loading and unloading system can be integrated to improve inspection efficiency;
• ​after-sales service: Vendor's technical support capabilities and equipment upgrade scalability are critical.
