General Industry NDT

Aqualified’s General Industry NDT services cover all aspects of non-destructive testing including structural steel assemblies, automotive parts, crane and rigging, DOT compliant tankers as well as commercial vehicle inspections such as fire trucks and any heavy machinery.

Structural Steel Assemblies

Most steel assemblies are designed and constructed in accordance with AWS specifications as well as ASME regulations. Aqualified provides clients with solutions that meet and exceed both governing bodies. Aqualified has certified CWI’s readily available to come to your site and evaluate your company’s needs in order to find the best and most cost-effective solution. Some common inspections performed are in accordance with AWS D1.1 and AWS B5.15.


Some common items of inspection with respect to steel structures may include bridges, structural joint assemblies, welded truss systems, and early pre-fabricated assemblies like that of constructed skeletal assemblies.


Weld Design


Engineers typically design welded connections in accordance with the requirements identified in the welding code. The codes address various aspects of the weld. Some of the weld issues specified are listed below:


  • Groove welds
  • Fillet welds
  • Weld length
  • Complete joint penetration
  • Partial joint penetration
  • Lap joints
  • Weld size
  • Weld spacing
  • Transitions
  • Static and cyclical loading


Structural Welding Code


  • Steel (AWS D1.1)
  • Aluminum (AWS D1.2)
  • Reinforcing Steel (AWS D1.4)
  • Stainless Steel (AWS D1.6)

Automotive NDT


Aqualified provides Automotive Nondestructive Testing with levels 2 and 3 technicians ready to service DOT compliant tanker and commercial vehicle inspections including fire trucks per NFPA 1914 and heavy machinery.


Non-destructive testing can ensure a salvaged part that is no longer manufactured, is free of voids and acceptable to return into service. Common defects found in salvaged parts include corrosion, pitting, mechanical damage, overheating, mechanic modifications and inappropriate pressing. When a vehicle part is obsolete, insurance companies and repair shops turn to Aqualified to provide ultrasound and radiography inspections on parts to ensure it is free from mechanical damages prior reuse. A vehicle rebuilt part or a salvaged part is full of unknowns. With X-ray, Ultrasound, Magnetic Particle, Liquid Penetrant, Eddy current, Conductivity testing, dimensional verification, visual and hardness testing, ensuring the integrity of the salvaged part before reintroducing it as a safe to use component.


Automotive NDT services Include:


  • Casting, forging and extrusion testing
  • NDT personnel augmentation
  • NDT technician training
  • Plant and manufacturing auditing
  • Vendor surveillance auditing
  • Diesel Engine NDT
  • Tractor NDT inspection
  • Off-Highway truck NDT inspection
  • Underground Mining vehicle NDT testing
  • Hydraulic failure crack verification


Non-Destructive testing is used extensively in Automobile manufacturing to ensure the integrity of ferrous and non-ferrous metals. Common inspections include Magnetic Particle and Liquid Penetrant. For vehicle wheel DOT safety compliance, radiography and liquid penetrant is often used. Proper assembly of airbags and seatbelts is ensured with radiography. From valve bodies to radiator assemblies, NDT may be used to ensure manufacturing conformance on automobile parts.

In-house service inspections include, crank shafts, piston rods, gears, transmission components, control arms and any other component in need of structural testing. Aqualified also performs nondestructive testing for the racing community including NASCAR, SUPERBIKE, INDYCAR and FORMULA 1 to name a few. We provide inspections for all race car teams both on tubular products and main body components.

Cranes & Rigging NDT


Aqualified offers accurate non-destructive testing (NDT) on all of your crane products. Our Level II and III inspectors evaluate integrity related and load bearing cranes and rigs. They determine whether or not you can safely utilize your equipment. At the end of the day, we provide you with great services and a peace of mind.


NDT on a crane


Aqualified can provide the nondestructive testing portion of your lifting device either onsite or at our facility. Lifting devices are visually inspected for excessive wear, deformation, out of plane bending, excessive gouges, and missing capacity markings.


Aqualified provides NDT on the following:

  • Sorting Hook
  • Duplex Hook
  • Shank Hook
  • Self-Locking Eye Hook
  • Self-Locking Clevis Hook
  • Self-Closing Bail Eye Hook
  • Eye Grab Hook
  • Clevis Hook
  • Eye Hook
  • Single Plate Hook
  • Self-Closing Gate Latch
  • Self-Closing Flapper Latch
  • Laminated Plate Hook
  • Foundry Hook
  • Clevis Grab Hook
  • Articulated Duplex Hook
  • Self-Closing Flapper Latch Swivel Hook
  • Self-Closing Flipper Latch Eye Hook
  • Self-Closing Tiplock Latch Shank Hook
  • Self-Closing Tiplock Latch Eye Hook
  • Chocker Hook



Aqualified will search for excessive wear on hooks during their annual visual examinations. After this initial NDT is completed, they will inspect damages through MT or PT testing. Throat and saddle measurements of crane hooks are taken to keep records of stretch or growth in damages from year to year. Once the inspections are completed, you will receive a NDT Certification Form to keep your devices updated until the following inspection.


The types of hooks that Aqualified performs NDT on:

  • Hooks
  • Cables
  • Fasteners
  • Bolts
  • Screws
  • Hooks
  • Welds
  • Studs
  • Nuts

Safety Standards


The American National Standards Institute enforces safety standards for all cableways, cranes, derricks, hoists, hooks, jacks and slings. The standards codes are ASME B30.1 through B30.25, and OSHA 1910.179.



Aqualified provides NDT inspections on bolts at our location or yours. Bolts play an important role in preventing NDT failure, so it is important to have them inspected properly. They come in various sizes, can be bonded to rock/concrete, and can be administered to anything made from metal. The two most common industries for NDT on bolts are mining and nuclear power. They can be found on infrastructures such as electrical towers, nuclear power plants, highway structures, dams, and large tanks.


Non-destructive testing can help find permissible and non-permissible discontinuities which occur during the manufacturing of screws, studs, bolts, nuts, set screws, socket caps, and other ferrous and non-ferrous metals. The most typical methods used for these materials include VT, PT, MT, RT, ET, and UT inspections. The two most common problems found with bolts are incorrect installation and over fatigued.



Welds are commonly used to join two or more metal parts. Sometimes these connections encounter heavy loads and fatigue, and may fail if not created to proper specification. Typical welding defects can include lack of fusion of the weld to the base metal, cracks or porosity inside the weld, and variations in weld density. These defects could cause a structure to break, or a pipeline to rupture.


Welds may be tested using NDT techniques involving RT, GR, UT, PT, MT, or ET. These tests will indicate a lack of cracks in the radiograph, show clear passage of sound through the weld and back, and indicate a clear surface without penetrant captured in cracks.


Contact us to have a third party look at your product. We have the skills to provide you with an extra level of protection for your company. All third party audits and test are maintained completely confidential. Findings and corrective actions can be executed onsite. Upon the completion of the project, a test report or an audit review will be provided outlining the results.
