What We Do

Our Services

Below is a list of some of our most commonly used structural steel services, inspections and non-destructive examinations. If you do not see what you need, please contact our office to see if we can help you in any way.


Structural Steel, CWI & Special Inspections

All Structural Steel Inspections are performed by AWS Certified Welding Inspectors. All inspectors have been thoroughly trained to properly perform Structural Steel Inspections both at fabrication shops and during erection.


Magnetic Particle Inspections

Magnetic Particle Inspections are used for locating surface and near-surface discontinuities inferromagnetic materials such as weldments, cranehooks, turbine blades, aircraft parts, gears, vessels, castings and piping. Despite its strengths, the method is not without its limits. The material must be ferromagnetic. Likewise, the orientation and strength of the magnetic field is critical. The method only detects surface and near-to-surface defects. Those further down require alternative methods. 

Liquid Penetrant Inspections

Liquid Penetrant Inspections, both fluorescent and visible, is a sensitive method used for locating discontinuities such as elongated indications and pours that are open to the surface. This method is particularly useful on materials such as aluminum, magnesium and austenitic stainless steel, which cannot be magnetized.

Ground Penetrating Radar Inspections

Ground Penetrating Radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. GPR can be used in a variety of media, including concrete slabs, walls and structures. It can detect objects’ changes in material, voids, and cracks with accurate depth estimates provided as well.

Ultrasonic Weld Inspections

Ultrasonic Inspections are used for thickness measurements and for detecting internal or surface discontinuities in almost all solid materials by using sound waves. Equipment is highly portable and especially useful when access to the part is limited.

Bolt Torque Verification

Bolts remain a critical component of the industrial world, supporting everything from bridges to pipelines, and are integral for the completion and continued function of any structure in which they are utilized. Bolt torque verification helps avoid costly disasters from improperly installed or maintained bolts

Qualifications & Certifications

In-House Quality Assurance

GPR Testing offers welding procedure and welder performance certification testing at the clients’ facility or in our laboratory. Our personnel will assist the client in preparing Quality Assurance/Quality Control Manuals (QA/QC), Welding Procedure Specifications (WPS) and Procedure Qualification Records (PQR) for the fulfillment of project requirements.
