practice welding question

[Rodsmachineshop]

my step dad when do steel worked work had a test like that . he said it was like welding steel but you did not get any penetration when welding the plates and he said you could use them over he had never seen anything like that before he thought was neat / had to me some special metal of some type

The only material that comes to mind would be carbon or possibly graphite plates..would like to see a set of those plates in action myself...

been surfing internet sure would like to know what there made of , I also had afreind at San Onfre nucular plant they use pipes for test welding that was the same way after welding they x rayed the pipe to see how the weld was . they was reusable to weld on, frank was funny he still works there he rides up and down the cooling pipes on his back wearing a radiation suit and ultra sounding the pipes lol he glows in the dark hahahaha

Most power Nuclear Power Plants have welders weld a pipe in the 6G position for welding tests.

At my plant we have the welders perform a TIG root and cap the joint with a few with stick passes. This is performed for both Carbon and Stainless materials and then the samples are x-rayed. Less than 30% of welders pass the test and many of these welders have 20+ years’ experience. Other plants may vary the test, just depends on what their program owner and the Level III inspector set up for the test.

As for radiation suits, there is no such thing as a radiation suit. Most radiation nuclear workers are exposed to go through clothing (Gama Rays). The clothing is used as a cover to keep contamination (activated materials or materials giving off radiation) off of workers. By keeping the contamination off of workers, the spread of contamination is better controlled.

What do they call this clothing ?

The clothing typically called PCs (Protective Clothing). Just as someone may wear gloves to keep chemicals off of their hands, PCs are worn to keep contamination off of your own clothing and body. Most Nuclear plants use Orex now days, a clothing that melts down with hot water. This clothing is awesome for disposal issues because it drastically minimizes disposal volume compared to the older cotton clothing.

yep.
yep,
and oh yea, every time I see a movie where they dawn the “Radiation Suits” it kills me. They are basically rain coats.

After the accident in Japan, my own Dad ask me why don’t they just get some of those radiation suits and walk in there.

Had to explain you couldn’t walk around with 3’ of lead strapped to you.

I am thinking carbon or graphite would be brittle to knock around. I would think they would shatter... But I could be wrong... Nice to know someone else has heard of them.

I came across some sites on testing blocks welding but did not say anything about them

I tried doing a search and came up empty... My internet has been screwed lately... Only running for a couple minutes an hour... Nice.... They have got some problem with several channels down.

I can not see how you could visually check if no penetration. And X-ray either. Maybe something to weld and break apart just to get the feel of welding and not so much test the actual welds?

I'll ask my Dad next time I talk to him (worked on cranes and cement plants most of his life and semi trucks).

But I have heard every welding story he has back to 50+ years ago and he never told that one. All the pipe welding (G) tests and certs.

And no doubt the man can weld and only requires a stick welder. I can't get him to take one our units, old school (and older now). But I know he would complain about MIG and never admit he likes the look of TIG.

I am curious. Sounds like it was not to test the welds as much as setting up the welder for it being in the right power range for maybe the rod??, but I do agree it sounds strange. He said it was only used on that one job. Never seen them used since.
