Our non-destructive materials testing group provides services for a variety of industrial, transportation and development clients. We’ve worked side-by-side with contractors, owners, engineers and architects to deliver quality service, earning us a reputation as talented professionals who work diligently to get the job done.

We offer a comprehensive range of non-destructive testing capabilities including structural steel inspection, welder certification, and pressure vessel and piping inspection. We also use leading technologies like Phased Array, which is particularly helpful in projects requiring limited access, rapid inspection of components such as welds, and for sizing defects and cracks. This method offers advantages over conventional ultrasonics and radiography and allows for improved accuracy and efficiency.

We have the experienced staff and resources to complete projects anywhere in the United States. Continuing education, training and experience keep the division staff current with the latest technology, codes, standards, specifications and techniques used in the materials testing industry. The team includes registered professional engineers, ASNT certified Level II and III non-destructive testing technicians, AWS Certified Welding Inspectors and API authorized 653, 510 and 570 inspectors.
