Which PMI Testing Technique Should You Use? LIBS vs. OES vs. XRF

Boots are best for working outside. Tennis shoes are best for the gym. Sandals are best for the beach.

Sometimes, though, footwear styles overlap each other. Maybe you need tennis shoes for working outside or sandals in the gym’s locker room. It all depends on the application.

The same can be said about positive material identification (PMI) testing techniques. There are three primary technologies you can use to carry out PMI testing. Test methods for PMI include:

Quality PMI Testing: 5 Tips to Ensure Trusted, Consistent Results

Posted by Chris Carolan on May 21, 2020 6:00:00 AM

If only life had 5 tips for quality results like PMI testing does; we would all be killing it!

Fortunately, for us metal heads, there are 5 clear-cut solutions to producing quality PMI testing results.

Positive Material Identification (PMI) testing is the analysis of materials to determine the chemical composition of a metal or alloy during alloy manufacturing, fabrication, installation or in-process inspection.

Portable Optical Emission Spectrometers (OES): Everything You Need to Know

Posted by Chris Carolan on Mar 19, 2020 6:00:00 AM

The manufacturing industry has little to no tolerance for error. That means suppliers often need to know the exact composition of the metallic alloys they’re dealing with.

Portable optical emission spectrometers (OES) have gained popularity in PMI testing. This is likely due to their portability and ability to provide the full chemistry of a metal including true carbon measurement.

In this post, we’ll cover questions around portable OES including:

 

What is an optical emission spectrometer (OES)? An optical emission spectrometer, or OES, is a spark- or laser-based system designed to accurately determine the elemental composition of metals by burning the metal surface and measuring the light wave emissions coming from the plasma created.

 

And specifically for portable OES:

  1. History of portable optical emission spectrometers
  2. Pros and cons of using portable optical emission spectrometers for PMI
  3. Costs of using portable optical emission spectrometers for PMI
  4. Mistakes to avoid when using a portable optical emission spectrometer
  5. Portable optical emission spectrometer brands

What is PMI Testing (Positive Material Identification)?

Posted by Chris Carolan on Mar 5, 2020 6:00:00 AM

It’s tough for me to hear about accidents in the news caused by faulty parts and materials.

Take, for example, the most recent SpaceX dilemma that caused Elon Musk’s rocket company to cut ties with PMI Industries. Because of falsified metal tests, faulty parts were shipped to SpaceX in order to build their Falcon 9 and other Falcon Heavy rockets.

 

"Failure to comply with quality control measures undermines the integrity of essential equipment and technology." - U.S. Attorney James P. Kennedy, Jr.

 

It’s possible that as many as 10 of SpaceX’s government missions have been impacted by the defective materials, including those with NASA, the Air Force, and NOAA.

That’s a preventable blunder with a huge impact. PMI Industries is now out of business.

Luckily, SpaceX had multiple points in the supply chain where PMI testing took place. They were able to identify at 76 individual parts that were rejected before making it to the final mission. Well done, SpaceX.

With the right positive material identification (PMI) testing in place, fatal disasters can be avoided.

 

That’s why I’ve dedicated this series of The Manufacturing Show to #MastersofPMI.
