PHAsisBLU spot weld inspection system with robots
Automated with robots
PHAsisBLU Spot weld inspection system
PHAsis®BLU was specially developed for time-saving robot-supported inspection of spot welds and short seams made of steel and aluminum.
It is ideal for testing 2- and 3-sheet joints with a single sheet thickness of 0.6 mm to 5 mm. The use of robot technology enables not only the reduction of the testing time but also the improvement of the reproducibility of the measurements. Cycle times of 5-10 seconds per spot weld are achieved.

The test sequence with robot
The PHAsis® inspection and evaluation software communicates the inspection plan with the robot controller via a standardized REST interface. Spot welds defined in the inspection plan are individually approached and inspected with the parameter sets defined for the spot.
A typical test island set up for 24/7 operation often looks like this:
Variant 1: The robot scans the part number and feeds the part to the fixed inspection unit.
Variant 2: Alternatively, a robot guides the inspection probe in the same way as the materials tester does by hand and moves it from weld spot to weld spot on a positioned component. In this case, the inspection probe is mounted on the robot arm together with the coupling agent inspection unit and the camera.
By coupling via a water supply line with a flexible plastic membrane, the inspection head can be precisely aligned with the weld spot, which is important in the case of displaced weld spots. A big advantage is the minimal wetting for coupling, which is sufficient when using the VOGT membrane. When using water, the advantage is that the sprayed water evaporates quickly. This eliminates the need to remove the coupling agent, which is also required by Rexolite solid-state leader sections commonly used this day.
The robot follows an inspection plan, so individual spot weld dependent setup and evaluation parameters are also automatically invoked. Inspection results are synchronized with host systems or/and the PHAsis database. In addition, the system offers a data manager as well as a post-processor for subsequent optimizations or special evaluations.
Delivery scope for the connection to the robot technology
We supply the following tools for use with robots:
PHAsisBLU can also be used mobile & manual
You can also use PHAsisBLU as a mobile inspection system solution for manual ultrasonic testing.
With our test trolley, you can transform PHAsisBLU into a complete, mobile workstation. It enables long-term operation without mains power with exchangeable high-performance battery units.
