The PHAsis.one manual testing device by VOGT Ultrasonics was developed for precise testing of resistance-welded spots. It’s ideally suited for the inspection of 2- or 3-layer joints with a single sheet thickness of 0.7 – 5.0 mm. 121 ultrasonic elements in an 11 x 11 matrix grant for a physical resolution more precise than 0.35 mm for the inspection of the nugget diameter. The imaging display guarantees a reliable evaluation of the test results. The generated cross section of the spot weld with colored depth imaging of the welded areas shows defects such as pores or a nugget that is too small.
Free testing made easy
In the „Free Testing“ mode, spot welds can be testes according to the motto “Quickly check the spot welds of component XY”. In contrast to the inspection according to a test plan, all ultrasonic and evaluation parameters are freely adjustable. The test personnel can either freely set all parameters – which requires ultrasonic inspection know-how – or access stored data sets; in this case he only has to select the material and the material thickness in the device menu. The latter is done when frequently identical materials have to be tested in order to avoid having to readjust each time. If not known, the individual sheet thickness can be determined directly with the wall thickness measuring function of the system.
Creating test plans quickly and reliably
To prepare a test plan, all spots welds of a component are often tested manually in an optimized sequence. The “Free Testing” mode is an ideal tool for this, because all data, sequences and results can be saved and transferred to a new test plan.
With the PHAsis.manager software, a test plan for a subsequent serial testing can be created on the PC based on the data obtained. This inspection plan is then synchronized to the relevant inspection systems and used by test personnel who require much less ultrasonic know-how. The user-friendly PHAsis.device test and evaluation software optically supports the user in the ideal alignment of the probe and thus contributes to measuring reliability.
PHAsis.one provides the user with information about the nugget diameter and detects the residual wall thickness of the welded area. The sound attenuation through structural transformation is also provided as a possible evaluation criterion for a zinc adhesion bonding.
For more than 35 years VOGT Ultrasonics, Hanover/Germany designs, configures and distributes automated and mechanized non-destructive testing systems and services for the inspection of metal and synthetic materials.
Innovative ultrasonic technology is the key to reliable and fast inspection in production and the laboratory. Whether it is a question of heavy-weight semi-finished products and forged parts, delicate welded seams or complex components: VOGT has a variety of methods and solutions to cope with the most varied of situations – from portable testing equipment to stationary high-precision systems.
