Krautkramer reports that it now offers a combination of instrumentation, application-based software and transducer technology tailored to the requirements of ultrasonic testing of spot welds on coated and uncoated steel sheet metal products.

This innovative technology is said to provide a cost-effective alternative to the destructive method of inspecting spot welds on a product by chiselling the individual welds apart. Automatic evaluation and classification of spot welds is accomplished using Krautkramer's laptop computer-based USLT2000 ultrasonic flaw detector with the application-based UltraLOG software and specially designed water column transducers.

The UltraLOG program stores and manages test results and evaluates spot weld echo displays, including weld flaw classifications.

Test results are under the control of the inspector. All test results are stored in the database on the basis of an individual inspection and test plan.

The inspection plans contain the number of the spot welds to be inspected, description of test location, material data, test diagrams and the complete instrument setting of the ultrasonic system. Several inspection plans can be predefined in the set-up mode.

According to Krautkramer, the most important ultrasonic parameters can be varied during the inspection; access to stored instrument settings is likewise possible without having to activate the ultrasonic software.
