Question

Dye penetration test microleakage advantages

Answer 1

if the working medium is transparent then it's necessary to check the leakage problem with dye penetration. you can easily see the colour pointing the leakage locations which otherwise is hard and expensive with other methods.

Answer 2

Many engineers and manufacturers choose the dye penetration inspection method because it’s quick and low cost. The penetration time can be as short as 5 minutes (or up to 30 minutes depending on the application).

In addition, dye penetration testing allows easy inspection of parts with complex shapes. This method also allows for quick inspection of large areas and large volumes.

However, there are also disadvantages. One is that the detection may be only limited to surface flaws. In addition, testing on rough surfaces might lead to false indications (due to difficulty removing the excess penetrant).

There are also concerns about worker safety. The spraying of the penetrant might lead to skin irritations, which is why proper training and handling is required for the procedure. It’s also important to perform a proper selection of penetrant and developer.
