What is Non-destructive Testing?

Advantages of non-destructive testing are numerous.

Non-destructive testing (commonly known as NDT) uses different methods to test, inspect and evaluate defects in materials or mediums without compromising the integrity of the product. Internal and external damages can be found, and the product can then be repaired or used after testing—this makes NDT an excellent choice when multiple parts or materials need inspection.

For example, NDT can be used to find defects in metal used during the automotive fabrication process. Advantages of non-destructive testing include the sample size, time, and most essentially—the product is able to be used or repaired in the future.

At Hercules SLR, we conduct two types of NDT—Magnetic Particle (MP) and Liquid Penetrant (LT) testing.

Advantages of Non-Destructive Testing in Langley, ON: what do we do?

Here in Langley, BC we use three main techniques when we conduct Magnetic Particle testing. These are Dry Powder, Black & White and Fluorescent Particle testing methods. Each has a specific application and sensitivity.

The most common items we get in Langley for testing would be Port Container Pins. We receive 50-100 per month. After that, our most tested item are tow sockets. We also do annual Lifting Gear Inspections. The Ports are a key to our future expansion here in Langley.

Dealing with the materials that we do, responsible disposable is more important now than ever. At the NDT department in Langley, we properly dispose aerosol cans and waste in designated waste containers that conform and comply with all environmental laws and standards.

Hercules SLR Inspectors: varied skill set

The CGSB (Canadian General Standards Board) is one of the biggest standard’s development and conformity assessment organizations in Canada, a part of the Government of Canada, Department of Public Works and Government services. They support the economic, regulatory, procurement, health, safety and environmental interests of stakeholders including government, industry and consumers. They’re also a charter participant of the National Standards System (NSS).

Essentially, having CGSB certification means you’re held to a very high standard and have the training to ensure you’re giving the highest quality service you can.

Chris Davies, our Langley Inspector has CGSB certifications in Magnetic Particle Inspection Level 2 and CGSB Liquid Penetrant Inspection Level 2; he’s also written his CGSB Ultrasonic Testing (UT) Level 1 exam.

Additional courses and certification that Hercules SLR technicians have include:

  • LEEA Rigging & Hoist Course
  • Crosby Clamp Inspectors Course
  • Kito Academy
  • Continental Rigging & Hoisting Certification
  • Confined Space Entry and Monitor
  • Fall Protection
  • Fire Extinguisher Training Certification
  • H2S Alive Certification
  • Management & Employee Relations Course
  • Dealing with Difficult Employees Course
  • WHMIS training
  • Lean Manufacturing/Production
  • 5S Production Methods
  • Dangerous goods training
  • Wildlife Awareness Certification

Advantages of Non-destructive Testing: technology keeps up

Connective communication technology plays a large role in NDT,  and the industry has embraced changes in technology and sharing knowledge.  We use the internet to source NDT-related blogs, sample defect photos and research on changing topics within industry. In the past, we only had very expensive books, manuals or had to make time-consuming phone calls to other colleagues in the industry.

Advanced technology has allowed us to move things a bit more quickly!

Non-destructive Testing: industry experience varies

We’re proud of the wide range of industry experience found at the Langley, Hercules SLR branch.

Chris Davies, a Langley Inspector who’s worked in aviation and oil and gas explains some advantages of non-destructive testing in different industries and the variety of experience they provide. “Aviation and Nuclear Industries are an entirely different world from the majority of typical day-to-day NDE Inspections. I only experienced this late in my career while working for the Oil and Gas Industry. The level of skill and experience varies due to types of inspections done, amount of exposure to actual defects and hands-on inspection, versus how long an individual has been licenced.”

He gives this example:

If Jane Doe works in the Aerospace Sector for 2 years, but works 7.5 hours a day on a wet bench (MPI) or dip tanks (LPI), she averages about 260 work days or 1900-2000 hours of experience per year and exposure to dozens of defects per day.

If John Doe works in the Oil/Gas Industry for 15 years, but works an average of 1-2 hours of actual hands-on and uses a Yoke and inspects on Closure, Socket or Stitch Welds. Let’s say he works a 10-on-10 off schedule. He works 183 days, or has 300-370 hours of experience per year and finds few defects per month.

The difference in hands-on experience is significant:

  • Jane, after 2 years, has almost the same hands-on experience as Joe has after 15 years.
  • Jane has over 10 times the exposure to find discontinuities (defects), versus Joe with 15 years of industry experience.

Advantages of Non-destructive Testing: found everywhere

Today, non-destructive tests are used in industries like Aviation, Space, Ships, Bridges, Refineries Mining, Nuclear, Manufacturing, Fabrication and in-service inspections.

Ever drive a car? Chances are, you use something in your daily life that’s been NDT inspected  at some point in time.
