The welding at 2.09 is not the welding described by the text. The video is rotation friction welding, where the friction is between the two round pieces being joined and there is no tool piece in the weld. Friction stir welding is where a rotating tool is forced along a joint creating heat and mixing the two parts being joined.Some of these machine tools are being operated without guards. This only happens in places where safety rules don't exist. Fingers, hands, eyes are regularly lost operating such unguarded machines. Regulations are a good thing when it comes to protecting workers. Unionize peoples!

I take this moment to give thanks & respect to the hard working people of the world who make the world what it is.Some build & produce by their back & their sweat. The real heroes of the world.This is just a shout out to all the workers out there, whatever your profession. Celebrating your skill and thank you for your hard work and service for us all.The dedication and work ethic displayed by these individuals are remarkable. Their commitment to delivering high-quality results while maintaining an impressive pace highlights the professionalism and pride they take in their work.

I thought in my trade of driving MR Mack trucks with triple steer front axles- and a 4 section 58 meter concrete pump boom was something. This makes me appreciate being able to operate and pump over 250 yds of concrete per hour. Trouble was having a supplier to keep you in mud to place.Fun fact. In Poland, the transport of such large, oversized loads can only take place at night. This is an additional difficulty.

I find it soothing watching people create products in factories. I'm a former paper maker so I find end products very rewarding.The traditional Korean bells look and sound amazing. Such a lot of work to make just one. I hope this traditional skill continues.All the engineering that went into all the machinery used to make all these products is incredible.

This is so painful to watch! I've seen many times where these are buried to the door and it didn't take no 2 hours to get out. I would have used some logs floats personally instead of them steel sheets.Wow, watching this was extremely painful, coming from a family of heavy machinery operators.If you drive by on that road above you can still see them trying to remove that machine today, it has become a tourist must see site. Be safe.

If anyone reading this should ever find themselves in the Miami, FL area, go visit the "Coral Castle", in Homestead. One man, Edward Leedskalnin, built it over a 28 year period. He was a Latvian immigrant who only had a 4th grade education, and was definitely NOT an engineer. Everything is made from limestone quarried from the site itself. When Edward bought the property, it was 'out in the boonies', and he had his share of privacy. Edward often worked late at night, never allowed anyone to watch him at work, and never told anyone how he built it or moved the stones around. The average weight of the various pieces is 14 tons each, the heaviest weighs in at over 30 tons. The construct includes various structures, including a 2-story "castle", an obelisk, various tables, chairs, the sun, planets, a 9 foot tall, 8-ton gate which is balanced so perfectly, a child can swing it open, a throne, and a 30-ton, 2 story slab which is part of a polar telescope. All hand-carved out of limestone and the stones all fit together so perfectly, no light passes between them.

Amazes me how they let some of these people into a machine to begin with.. the demo guys all did a good job too.If you going to name a video fails, then make it all fails, the building collapse videos aren't fails, they're purposely being torn down.It must suck knowing you've destroyed your country's only working excavator.Someone should tell these excavator operators that the counterweight is much heavier that the bucket.

I was a power lineman and working in the Irvine area and getting ready to set an hundred foot steel pole. Forty feet of it went into the ground. While digging the hole with a well digger we broke through the ground and there was a rushing river at the bottom of the hole. Frankly it scared the heck out of me. If you fell into that no one would ever see you again. We had to dump abound 20 yards of concrete to bring it up to where we could set the pole. We set the pole and encased it in foam.

This incident happened in the Port of Hamburg on the Ferry "Tollerort" on line 68 bringing some Airbus Plant employees to work in the morning. According to the Police three people sustained minor injuries, i.e. cuts from shards of the broken window. The ferry, which is part of the Hamburg public transportation system, was never in peril and moored at a terminal where the passengers could disembark. The injured were treated by a doctor of the public transportation operator. One was treated as outpatient at the hospital (everything covered by insurance). One lady, who got soaked and also sustained cuts on her hands, went to work after receiving treatment from the operator's doctor.The glass panes are supposed to withstand such stress and this has never happened before, which is why the incident is now under thorough investigation by the operator and the authorities concerned.

The real danger here is the guy that “saw that coming” and chose to do nothing. Those are the types of guys that get people killed on sites.As my grandad used to say “the man who never made a mistake, never made anything”.“Saw that coming” Being a foreman, I always give the veteran guys shit when they witness a green horn fuck up like that, it fucking boils my blood. Especially when they record or shout to other guys and tell them to watch. We all started from the bottom at one point, so do the right thing a speak up.
