PHAsisONE inspection device – high precision with fast imaging evaluation
The PHAsisONE ultrasonic inspection device (fig.1.) is designed for the precise inspection of resistance welded spots of steel- or aluminum sheets. It‘s ide-ally suited for the inspection of 2- and 3- layer joints with a single sheet thickness of 0,6 mm - 5 mm.
PHAsisONE is the first phased array ultrasonic inspection device offering a physical resolution of the spot weld diameter more precise than 0.35 mm. 121 ultrasonic elements are used in an 11 x 11 matrix. More than 700 measuring points per welding spot are recorded during the inspection.
The probe (fig. 3) is connected to the test part by means of the water delay path and its reliable bubble technique. Several standard water delay paths as well as further application-specific water delay paths can be used flexibly, depending on
accessibility and surface quality of the test speci-men. If required, the use of a fixed water delay path (rexolite) is also possible (see technical data sheet).
The inspection time is just a few seconds per spot.PHAsisONE provides data on the diameter of the welded spot, the remaining wall thickness of the welded area as well as the sound attenuation caused by structural transformation as possible evaluation criteria for zinc adhesion bonding.
The compact and robust housing and its low weight of 3.5 kg make PHAsisONE the ideal equip-ment for mobile operation.
Central administration of inspection plans and results
All data is organized by means of PHAsisMANAGER administration software and synchronized with the PHAsisONE ultrasonic inspection device.
If needed PHAsisONE communicates with the customer‘s data base by individually adapted inter-faces.The data and user administration as well as the creation of various inspection plans are clearly designed for easy and fast editing.
PHAsisMANAGER also has an interface for the data import of test plans as CSV files. This simplifi-es the creation of extensive test plans.
Mode „Testing according to test plan“
In this mode, the inspection plans are created by an experienced ultrasonic inspector and made available to the users by means of synchroniza-

tion with the individual inspection devices. As a result, the users no longer have to make any test settings. They only inspect the spot welds using the visually displayed test plan. This means that even test personnel without in-depth knowledge of ultrasonics can perform reliable testing.
Mode „Free Testing“
The mode „Free Testing“ enables a fast inspection of various spot welds, detached from set inspec-tion plans (refer to fig. 5). Therby the user has still access to the full functionality as known from the mode „Testing according to test plan“.After the inspection, the results of the free testing can be transfered into an inspection plan and a standard inspection.

Intuitive software for a fast inspection
The PHAsisDEVICE inspection and evaluation software on the PHAsisONE device is specifically designed by VOGT Ultrasonics for quick use during production. The intuitive operation guarantees a minimum need of training.
PHAsisDEVICE supports the customer with a live C-Scan and time-of-flight-based alignment pointsfor the optimum focussing of the probe on thespot weld to be inspected (fig. 6).
The imaging display of the phased array techno-logy ensures the safe evaluation of the inspection results.
The created display of the spot weld with coloured depth imaging of the welded areas (D-Scan) shows defects in the welding, e.g. pores or too small welding spots. By freezing the D-scan PHAsisONE automatically provides an evaluation proposal (fig. 7).

PHAsis in use with robot technology
We supply the following tools for use with robots:
▪ Communication interface: Automation inter- face, PHReAP (REST-interface), interface
licence / interface licence for remote control for every PHAsis ultrasonic inspection device, incl. detailed description
▪ Probe holder incl. water coupling nozzle forPHAsis probe diameter 24 mm for mountingon a robot
▪ Reference plate with reflectors for systemmonitoring and calibration
▪ Export interface for test results, importinterface for test plans
▪ 4 distance information for vertical alignmenton the spot weld surface via automation inter-
face
Furthermore we also offer a Cobot, which can be used with the PHAsisONE ultrasonic inspection device as a unit for the inspection of joints. This is a Franka robot, which can be easily teached by an experienced inspector or an inspection su-pervisor. The robot and PHAsisONE can be used as a mobile unit and achieves excellent results.
Such robots can make spot weld inspection and longitudinal weld seam inspection less expensive. Instead of manually testing with one device, the inspector can test several components simulta-neously with 2-3 Cobots. We would be pleased to present the concept to you.
Module Longitudinal Weld Seam Inspection
PHAsisONE is also ideally suited for the inspec-tion of longitudinally welded seams, e.g. Arplas® weld seams or short-lined weld seams (see Fig. 8). Longitudinal weld seams with a length of 3 mm to 12 mm can be tested. For this purpose, the same probe is used as for the testing of spot welds. Furthermore, up to two partial lines (maximum interruption length can be set by the user) can be defined as one seam. Fig. 8:
