Nondestructive Testing

In February 2017, Northern Technologies, LLC (NTI) acquired key assets and personnel of Midwest Industrial X-Ray (MIX) allowing the expansion of our professional nondestructive testing services. NTI’s nondestructive (NDT) services include radiography, X-ray, ultrasonic thickness, shear wave & C-scan corrosion mapping, magnetic particle, liquid penetrant, certified welding inspections, welding qualifications, quality assurance, concrete inspections, and ASNT Level III services that can be conducted at the jobsite or in our laboratory.

NTI and MIX have collaborated together for almost 20 years on a wide variety of projects, which will provide a solid foundation for the integration of our teams. The NTI NDT team will retain its embedded value in the form of the same employee team in Fargo in the same space, thus allowing us to continue to serve the demand of our clients.

Our professionals are certified under the written practices of ASNT (American Society of Non-Destructive Testing) and provide NDT and inspection services in all aspects of the oil and gas industries, transmission, refining, storage facilities, and oil related support industries as well as inspection services to the chemical, manufacturing, food processing, building / structural, agriculture, machining and power industries.

We look forward to bringing you the highest value for the services you need. Please contact us at 701.282.7846 for all of your NDT testing needs.
