Is it scientific to inspect the quality of groove fittings through tapping?

How to identify the quality of groove fittings is crucial. Perhaps many times, we become helpless because we don't know how to identify or identify the quality of groove fittings, or we purchase some unqualified products for use in engineering, and we don't know, we can only accept it. Many times I hear people say that using tapping to identify the quality of groove fittings is not scientific. Today, let's give a brief introduction to tapping methods to see if they are truly as magical as the legend. The inspection of trench fittings by tapping is as follows: by tapping on trench fittings, the quality of trench fittings can be understood through sound and sensation. By tapping, it is easy to understand whether the toughness of grooved fittings is good.
The selection of groove fittings is a complex process, and users must carefully choose products with good quality when making purchases. They cannot focus solely on the advantages of one aspect and ignore the overall performance. So, when we inspect the quality of groove fittings, in addition to tapping them, we can also use other methods comprehensively to ensure the quality of our products from all aspects. At the same time, if the tapping method distinguishes the quality of groove fittings as unqualified or unscientific, we can also make up for it through other methods.
