Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a multi-channel type ultrasonic leak detector for transmitting and receiving ultrasonic waves,

The present invention relates to an ultrasonic leak detecting apparatus capable of detecting leakage through ultrasonic waves, which is capable of utilizing ultrasonic waves as a whole, as well as transmitting and receiving ultrasonic waves.

In the case of a piping material made of a metal material, a small-diameter piping material having a small diameter can usually be manufactured by the same method as a drawing, but a large-diameter piping material having a relatively large diameter is produced by bending a metal plate into a circular shape and finally welding to form a closed piping material do.

In addition, the welding process is used not only for the piping as described above but also for various products.

Such welding is a very efficient joining method, but it has a great influence on the welding quality due to the working skill of the welder and other working environments. Various types of welding defects may exist and the welding site is fundamentally vulnerable to shock, so careful attention is required when carrying or storing.

In some products, there is a need to prevent dust and foreign matter from entering into the inside or water into the internal substrate, and since the piping material is also used to transport the fluid, it should not leak any fluid such as water, oil or other gases do.

If there is a defect in the welded portion and the jointed portion of the product or pipe requiring sealing / sealing as described above, leakage of the fluid causes many problems. Therefore, products and piping materials that are essentially manufactured should be tested for leaks.

Typical leak tests include water pressure tests or barometric pressure tests using helium or other gases. However, in the case of submergence (water pressure) test in which water is submerged in the conventional leakage test, it takes a long inspection time and depends on the manual, and there must be a drying process for drying the product after inspection, In the case of the differential pressure method using the differential pressure, there is a problem that the charge time stabilization time is long although it is determined based on the reduction value of the pressure by the differential pressure sensor. In the case of the helium test, And the like, the detection performance varies depending on the change of the air pressure factor and the like.
