This method is used for testing neatly solid materials (fine-grained aluminum, steels, alloys, composites, and plastics), and is highly sensitive to discontinuities that are most critical to structural integrity, such as lack of fusion in welds, incomplete penetration of welds, and indications in welds. It is highly portable, and usually requires access to only one side of the object to be tested. Utilizing ultrasonic, our technicians can detect internal discontinuities and measure thickness.
