Problems solved by technology
Therefore, once the product has airtight defects, the subsequent surface of the product needs anti-corrosion treatment, such as electroplating treatment, but the electroplating treatment will cause the electroplating acid solution to penetrate into the product and cause the product to be scrapped, and the quality of the product is difficult to guarantee. Therefore, the product after welding Flaw detection is often required
[0003] At present, the traditional non-destructive testing requires the use of professional equipment and the cost is high, the detection efficiency is low, and the high misjudgment rate of welding air tightness cannot be guaranteed, and it is even harmful to the human body, such as radiographic testing.
However, penetrant flaw detection has many procedures, slow speed, expensive penetrant reagents, high cost, high misjudgment rate, and flammable and toxic materials.

Description
Technical field [0001] The invention belongs to the technical field of non-destructive inspection and flaw detection, and particularly relates to a convenient and efficient foam-type non-destructive flaw detection and testing device, especially but not limited to the air tightness test of the product after welding. Background technique [0002] With the improvement of the production quality and processing technology of welding products, they are widely used in many fields. However, welding products often need to withstand a certain amount of pressure. If there are cracks or holes on the product, it will cause fatal defects in the welding product with tightness requirements and cannot be used normally. In severe cases, it can even lead to extremely destructive accidents. Therefore, once the product has airtight defects, the subsequent surface of the product needs to be treated with anti-corrosion, such as electroplating, but the electroplating treatment will cause the electroplat...
