linear friction welding has been added as a related post - related requested by newtboy on that post.

This is just like ultrasonic welding that they do with plastic, but way more powerful. The movement creates friction and heats both parts to liquid, then stops at the proper alignment so it becomes one part when the metal solidifies almost instantly.
Reminded me of this....

Actually it was rhetorical, I knew where I was going to start, I was not asking you in a real way or expecting you to answer...that's what rhetorical means.
Because the video was limited to American schools and systems does not mean the comments will be, we have a diverse bunch of sifters from all over the globe that might want to comment, and might not stick to America as the only place that counts. It is logical to ASSUME you might have meant only American schools, but some of us don't assume we know another's meaning and just go with what you wrote. If you wanted to limit your comment to American schools, you could easily have written exactly that. There's not a character limit on posts!
Or, perhaps Bareboards2 knows some Americans that would be insulted by your painting them as lowest common denominators at their basest. I would be one. I admitted those you describe exist, and may even be a majority, but Americans are not homogenous by far, and there are many that do exactly what you claimed they don't.
It's not hard to CARE, it's hard to retain, it's hard to focus, it's hard to attend at times, it's hard to come up with supplies, it's not hard at all to CARE about education, and I've never met a person of lesser means that didn't wish they could get more education. Saying they don't care is insulting, saying they don't achieve (as well as rich counterparts) is fact, sad tragic fact.
Yes, I agree, we need to help the poor a LOT more, their plight is getting worse daily while those not in need are the only ones succeeding.
I'm right there with you on free higher education, for the betterment of the nation AND it's citizens. College grads are far less likely to commit violent crimes or otherwise be drains on society, so are a boon for all.
It sounds like you may be confusing a lack of time, money, ability, and energy with a lack of caring, or perhaps not. As I said, those you describe do exist, in large numbers, they are simply not the ONLY variety of American student.
What?!? If this woman is in class working and paying for a degree while trying to raise 3 kids, one disabled, it sure sounds to me like she CARES about education, and that she's not lacking in educational pursuance or lack of drive, she's possibly failing for lack of energy and time would be my guess, or maybe from lack of educational preparation, or innate ability. If she didn't care, she shouldn't be spending money and time being in class working for a degree that no longer guarantees more money, she should be in welding class, or making bank cleaning up the school. There's nothing wrong with that, I've done both. People who only want to get more money and don't care about knowledge should go that route, they'll have a much better chance of success and not be in crippling debt for a chance they'll use their diploma for financial gain.
WTF?!? When they stopped the abuse, did you care then? The poor have tribulations, but are not constantly working to the bone unable to even contemplate a better future because they're outrageously accosted by life every second of the day. Be real. When there's time to think, many people of all social strata think how they would like to lean something new. You obviously cared enough to be in classes now even with this abuse you speak of, just like I did when and after all those things happened to me (but with only one brother. For me it was actually incentive to learn more and be 'better' than my brother whenever possible, in order to have a better life, I know I'm a freak though ), so what's your point? The poor don't think about furthering their education 100% of the waking day because they're too busy being poor, so they don't care about it at all? That's just silly. I think many if not most don't think about it much because they've determined there's no reasonable opportunity for them to achieve it, so why dwell on what you can't have. It' s not an issue of not careing.
I think we should help them have the opportunity to gain higher education and ability to make use of that opportunity because we know most of them DO CARE about education, but could certainly use help to achieve it. Those that don't care (I again admit they exist, but not only among the poor) should be helped to care, because it's important for them and us to have everyone educated.
Jon Stewart was generalizing, not making a statement about each and every American. I only take issue with the broad brush strokes painting all Americans in the same ugly color, I think we're a quite varied and interesting group, and I don't resemble your generalization in the least...and I'm American. I did admit that I think many, if not most Americans do fit your description, but you seem to still take exception to that viewpoint.

Padding? Who needs any padding!

Also it's not a outdoors gym. It's a kids playground. But with all the anti-theft chains welded on, they only ones who can play there are weightlifters.

Can't stand politics. Apolitical. In a reasonable world, politicians would be rounded-up and placed in internment camps awaiting trial for crimes against humanity....Or wait, that's too harsh-Dress 'em in clown make-up, strip 'em naked and toss em one by one into oncoming roller-derby traffic for a few healthy rounds of clothes-hanging.

'No Country' and 'True Grit' of the last 7 films (did love the scenes with Richard Jenkins and J.K.Simmons though in Burn After Reading, otherwise that film was simply hard to watch) and of course Lebowski and O brother....but seriously....Inside Llewyn Davis? What more of a complete piece of shit can one imagine?

Imagine if you will, two Jewish men driving down the street laughing at people while throwing burning hundred-dollar bills out the window.

A series as a nod to Fargo screams rehash of pop-culture on the fucking skids and a reason to spend your cable money on learning to plasma-weld or something.....

Welcome back BTW @volumptuous. Still got yer Aunt Jemima Cookie Jar

Last time I tried to vote they turned me away at the polls in that rigged election-machine Gore/Bush election back in 2000....I was gonna write-in a made-up name. I realized that year that my mission was to decry all presidential elections as complete and utter farce and an insult to the collective consciousness.

It seems that this is simply a robotic MIG welder set at low power/high wire speed and grounded to the floor plate. It would likely not be good for anything structural, but great for art and the like.
Neat!
Side note, that guy should be wearing a face mask, and the window should be UV tinted to avoid blinding people watching, welding is dangerous if you ignore the safety equipment (my eyes were damaged by it, and I always used proper safety equipment).

I took HROP welding at that high school...17 years after this.

Ah, I can see you have a FORT in mind. There is no FORT, really. The whole area is the Fort, the land itself. The "blocking fort" ARE the bunkers -- on top of the bluffs and at water level. There are two other forts in a triangular shape -- one on Whidbey Island and one on Marrowstone Island. The idea was if any boat came into the waters of Admiralty Inlet, one of the forts bunkers' big guns could take them out.

The bunkers are all still there. They were going to jackhammer them away, but they were made from imported Belgian concrete and they just would NOT break up.

So you can go crawling around in all sorts of bunkers. Some of the rooms have had their doors welded shut, for safety reasons. But there are plenty to explore.

These three forts aren't on an estuary, however. It is ocean water, but not the ocean. The Pacific Ocean stops about where the Northwest corner of the Olympic Peninsula is kind of south of Vancouver Island, in Canada. Things get narrow there, and the ocean waves can't reach. Or something. So there are bodies of water that ships and boats follow going east, then they turn south to Seattle, which is on the coast of Puget Sound.

It's all very confusing. I can never figure out which way is north. Port Townsend has water on three sides, fer pitys sake!

Oh, and they did remove the big guns, even as they left the bunkers. You can see where they were and get a good sense of how big those guns were.

None of the three forts ever shot in anger. Just practice.

Exactly! "Shop fronts" only.

So when are you coming to America? It is beautiful in my part of the country, albeit very young by European or even East Coast standards. We are very proud of our oldest building. I think it was built in 1875 or something. Maybe even later. Ha.

i tried my hand at this.
i apprenticed under a man whose daughter i was dating at the time.
yeah..i was young and didnt really think that through.

his technique was nothing like this though.
lots of hammering and welding and cutting.
good god it was dirty and i was pretty awful at it.

Interesting, must be a fairly constant temperature there.

In my country they welded the rails together to save money on maintenance, which was fine until the next hot summer when they all expanded and buckled.

Your video, Railroad Thermite Welding, has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

His welding looks a lot like soldering.

Dude, you had a golden ticket in a frozen market as a daily head and blew it-only up from here! I'm telling you, spend the next ten years learning to weld pipes n shit!

Comcast sadly, is the only provider with decent speeds for the needs around my general area-All the "G" networks blow for Mbps. Comcast's internet only package is about 10 bucks less than a bundle with cable so.......For the first time in about 30 years, there's television programming in the home.

After about 3 months now, I'll turn the thing on when I am washing dishes and all I do pretty-much is parody the adverts, re-scripting them in my head like I'm working on a pitch.

After so long without any alternative programming than that of my own (save a bit of F.M. radio whilst driving), my bullshit detector (located near the conarium at the cerebral juncture) goes off at the slightest movement of the continental plates in New Zealand.

I see myself doing without the internet in the future as well as mobile devices beyond a basic cellphone-Probably give them all up for a variety of diversions like welding, tending animals, and building all manner of objects d'arte, to sell to folks to put in their homes next to their televisions, or connect to their many devices-

Now you know my 20-year-plan, see you at 68, update in ten....

Is he wearing welding goggles?
