Another Happy Graduate of AINDT!

Hey guys,

I just finished my first week and thought I'd share what it has been like. Of course, I'm just assisting on these for now, but once I get my certs, I'll be out there on my own doing this stuff.

Day 1: MT on welds for a piece to be used by a private space exploration company.

Day2: UT lamination scans on large steel plates used for construction of a new ferry.

Day 3: PT on welds for ferry construction; UT shear wave on pipe welds

Day 4: UT thickness gauging the hull of a small freighter

Day 5: UT thickness gauging safety pins on the top of a grain elevator (about 100 feet up, harnessed and dangling off the roof); MT on a repair weld for the boom of a cement truck

Never know what the day will hold for me, and I really like that. No RT, which is unfortunate. We've mostly got maritime customers, but it seems like there is quite a bit of railroad, construction, paper mill, and manufacturing customers, too.

It's a good gig. I'll let you know when another position opens up.

Thanks again for everything,

Morris

Understanding Hydrogen Induced Cold Cracking in Welds

Karsten Madsen | Apr 26, 2017

"Like others, I probably contributed to some weld cracking earlier in my career through ignorance about the effects of hydrogen on some metals. Problem #1 … working as a young Welder, there was usually a stash of 7018 electrodes somewhere handy saving a trip to the holding oven. Problem #2 … I'm showing my age in saying that at that time, microwave ovens had not yet showed up in cafeterias to warm up meals. No problems though as electrode ovens did a good job of heating up leftover mac 'n cheese or a can of baked beans for a warm dinner.

Adding to our ignorance, the welding rods used in both of these circumstances seemed none the worse for the wear making welds that appeared to be acceptable. So the loosely applied rules about keeping the electrodes only in dry holding ovens and used within 4 hours did not seem to justify compliance. Moisture absorbed by SMAW electrode flux coating is only one source of hydrogen entering a weld deposit. It can also exist in FCAW wires, SAW flux or come from high ambient humidity or lubricants used in other manufacturing processes. Moisture of course is hydrogen and oxygen while oils and greases are usually hydrocarbons.

My intent here is to explain in understandable terms why it is so important to control weld exposure to hydrogen for those higher strength steels that are susceptible to hydrogen induced cold cracking (HICC). I’m not a Metallurgist and I may be taking some liberties in the following explanation, but to me at least hearing the effects of HICC first hand and my analogies to explain this phenomenon seem to make sense."

NDT Training: The Best Investment You'll Ever Make

Title: Choose A Career In Nondestructive Testing

Make A Great Living In A Growing Sector

"It’s no secret that the US economy, and the global economy in general, have seen some tough times. Many sectors were slow to recover from the 2008 recession, and for the American middle class, things aren’t getting much easier.

In many career fields, an expensive college education leads to a middle class income saddled with student loan debt. NDT (nondestructive testing) is one incredible exception. A career in nondestructive testing requires a relatively small investment in education, and the payoff is an excellent salary.

Just how excellent is that salary? Glad you asked. We researched education and salaries for various careers and compared the results to a typical NDT salary, as reported by PQNDT in their annual NDT salary survey. Check it out–and check out the full survey from PQNDT. Whether you’re a seasoned NDT professional or you’re considering a career in NDT, the survey from PQNDT is an incredible resource."

Emerging Growth Markets for NDT

The emerging markets for NDT inspection services are Brazil, China, India, and South Africa. Surprisingly, of these markets, China is the smallest. This is due to the trend in China wherein end-user industries prefer performing NDT inspections in-house rather than outsourcing. Similar to the global NDT inspection services market, these emerging growth markets are characterized by a large number of competitors, although most participants are relatively small. 

End-user industries such as oil and gas and power generation are the key drivers. High oil and gas prices have ensured that the operators earn significant revenue. This revenue has been duly invested back into developing the infrastructure in the energy industry.
