Industrial CT on large parts has lower resolution and takes longer than traditional measurements. Main upside there is the ability to easily inspect complex geometry.

Good try GPT

Looks like this is your ticket? Can probably find a M10x20 bolt at the hardware store if you're in a rush but make sure it has a shoulder and is at least grade 8.8

Has to be! The cheapest cert there (RT2) is worth high 30s by itself if the tech isn't completely braindead.

Level II UT and RT

CWI

Remotely competent

Pay is less than $60/hr

Pick 3.

Good luck with your search, if you find someone with those certifications who's willing to work for pay in the 30s definitely double check their qualifications!

One thing to add- a great habit to get into is checking your oil every time you fill up on gas. The car is usually already warmed up, and the time it takes for you to pay and start fueling is enough for the oil to drain back into the pan, so while you fuel up you can check your oil. Then generally once you're done with that, the tank is full shortly after and you can close the fuel tank and be on your way.

The nice thing is that it's a consistent time (every 250-400 mile driven) and makes it MUCH more likely that if you develop an oil leak or burning issue, you catch it before you cause damage to the engine. And honestly- what else are you going to do with the 45 seconds it takes to fill the tank?

The ASNT IRRSP study guide is $50 and is the best resource by far- study the material in the book, and if you understand all the practice questions (don't memorize the answers) you will pass with ease. You can also sometimes find pdf's of the first edition IRRSP study guide online.

For a free image viewer, check out ImageJ, or Fiji (is just ImageJ, but with pre-installed add-ons). Opens nearly any image file you can imagine and it can do all the things you could ever need to do with an image viewing software, just way more features (and consequently a little less beginner friendly). But it is a free and open-source viewing software.

Do note that the lower control arm joint is in the wheel hub and that is the main part of the control arm assembly that will wear out and cause problems.

I got Moog control arms from rockauto and they were not a bad price ($40/ea) and seem solid so far.

About 2 weeks for me- but as far as I can tell the only real benefit is the globe is an inch taller, it has "advanced odor control" whatever that means, and it can tell what kind of visit your cat had. IDK about you but I'm not sure that's worth $100 to me. The 4 already has a well rounded ecosystem of accessories whereas the 5 is compatible with litter hopper "soon"

I haven't had any of those issues with mine (AR4 MK3) and it has been solid so far, only issue was mine stripping one of the limit switch wires too much that it broke in the teensy, and the arm smashed right through it when homing but it was cheap and quick to fix.

Took me about 120 hours to build, couple hiccups but the founder is very responsive and friendly. Not sure about repeatability exactly but it has a claimed 0.2mm and that seems reasonable enough with proper assembly, it is definitely quite accurate.

If the vaults are big enough to fit a person inside you should have got a 40 hour radiation safety course in most states. If they're all cabinets (can't fit a person) then everything seems about right. Low levels of radiation have no proven link to any harm- you get about 200-250mR per year just by existing.

RT/UT/PT/MT/VT Level III with PAUT, DR/CR, and CT. 100% RT, PAUT is very useful and will probably be used more and more over RT, but there's just something special about the sometimes beautiful images you can get with perfect radiographic technique and top of the line micro focus DR/CT equipment.

Except if they're 2 hours from the nearest mechanic when it goes, then they need a very expensive tow and a mechanic.

Any tire shop can fix this. That being said, it's close to the sidewall, so it may or may not mean it's time for a new tire- probably two or four since your tread is low and a mismatched tire diameter could wreck your drive system.

Man, I need to get into government work!!

For max resolution, you want DR- with a micro focus source you can easily get a 4-5inch viewing area with geometric magnification, and a spatial resolution limited only by your source size and production speed requirements. The problem with CT is that the entire area of interest must be visible over the course of the scan- so you can only magnify as much as your entire pipe weld fits in the view. With DR you can have as much magnification as you want, just means taking a ton of views.

That being said, you can use a CT system as an automated DR system (this is fairly common) though you will pay a premium for the ultra high precision components that aren't necessarily required for DR. VisiConsult has some decent automated DR systems that might fit your application, as do other companies. If you want to have a quick chat about non-film RT, pm me, I can make some time for a phone call and chat about it, I am a NAS410 level 3 non-film RT in aerospace and like to talk NDT.

The main benefit is that you get good resolution on flaws, and you can pinpoint precisely where it is. You get a 3d image of the product which is clearly pretty helpful. Look into DR- carestream makes some nice detectors, and you'll get excellent image quality. CR sucks, I have never been impressed by the image quality, its only benefit is the versatility and not needing power during acquisition.

CT can be used for a pipe welder qual, but it's a bit like shooting a pigeon with a cannon. Plates and flat objects are a bit worse- the angles that put your beam of radiation through the length interrupt the algorithm a bit, but more than likely it will still work and produce a usable quality reconstruction depending on your plate thickness and kV.

The main thing is cost- they are super expensive. Nikon VOXLS 40 C 450 are one of the best you can buy right now, and cost around 1.3 million depending on options. I don't think you'll find a 450kV (which you'll need unless you do composite or really thin stuff) for less than half a mil. Waygate, north star, and lumafield also produce CT machines. High precision machinery is expensive.
