Def on this point; part of why i tracked down one of the studies instead of 'people say;' not one-size-for-all nor is outright recklessness needed. Say what you will on those parachuters up there, them being unskilled isn't one of those things you can claim. ED: Hell of a snipe, Reese. Have some top-notch scaffolding.

Someone read a paper about exhaust pulse scavenging, took a very large pull off their vodka bottle and looked at their fume extraction system with a new found purpose.

Usually when those videos are posted it’s 2 or 3 guys standing right beside the platform turning the metal while the machine flattens it so this is a step up.

This is why when doing animal rescues like this you a) have the animal blindfolded/hooded so they can't see which keeps them calmer and b) have a vet on hand to drug the animal first so it doesn't do this.

Ok so I'm not going to think that someone here knows whats specifically being made, but what the poo poo is going on? Like they're forging some Iron, or steel, but what would be the end result? Does this piece get sent somewhere to be machined in to product X? Ir does it get cut in to pieces and then further stamped/forged? I know that "hardened" steel (there are lots of types of hardening) is more difficult to machine, but what about forged steel? Also more difficult? Less difficult than if it had some sort of hardening process done to it?

This is a powerhammer, there are all kinds of these devices and they are used to forge huge cast iron blocks into a more desired shape and also to strengthen the iron/steel. It will be cut up or put into a dye and hammered more, or both, and eventually machined into probably some gently caress off huge gears or heavy industrial poo poo. After that it can be hardened by being heated and cooled in a specific way.

wesleywillis posted:Ok so I'm not going to think that someone here knows whats specifically being made, but what the poo poo is going on? Usually in these videos they are making some kind of giant pipe flange or similar fitting, used either for fluid-carrying pipes or to connect structural members together for a bridge or something. Yes, the part will be machined to the exact size afterwards.  Here is a video that shows the whole process, along with photos of the machining at the end. https://www.youtube.com/watch?v=_0bbTZrcYMc There are basically four ways of making something like that: 1) start with a huge square billet of steel and machine the whole thing out 2) cast the object in sand and machine it down to size 3) forge the object from an ingot and machine it down to size. 4) weld several smaller pieces together and machine the joints. Machining from a billet is extremely slow, wasteful and costly, both in terms of material and tooling. Sand-casting is effective, but because the metal crystallizes in the final form, cast parts can be brittle. Heat-treating can help somewhat. The main advantage is that it's quick and only uses as much metal as is required. Forging makes the strongest parts, because by repeatedly hammering the metal and flowing it into shape instead of just freezing it, you work out all the voids and grain boundaries. The crystals align with one another and release all their stresses. You also can start with a lump of metal that's only as big as you need. Welding several pieces together is effective if you haven't got heavy tooling, but the welds are potential weak points. Basically, for this type of application forging gives the strongest parts with the best material efficiency. The only real downside is that it requires very large heavy equipment. Here is a nuclear reactor pressure vessel being forged. A piece this size could not realistically be cast or machined, and a welded/bolted/riveted design would have obvious weak points. Forging is the best technique.  e: re. "hardened" steel -- a whole other can of worms. The final properties of the steel depend on its exact alloy and its heat treatments. It could be hard and brittle, or flexible and tough, or somewhere in between. A flange will be closer to the tough end because you don't want it to fracture when the bridge or pipe shift around. Regardless of the alloy, when it's being forged it will be in a malleable state, and it will cool to an annealed (relatively soft [for steel] and tough) form. If it needs to be hardened for extra wear resistance, they will perform steps like heating and quenching it after the machining is done. If the hardened part has to be re-machined to size, they will grind it afterwards. Sagebrush fucked around with this message at 01:41 on Sep 28, 2020 |

He was wearing full face protection as well as heavy gloves like one should. He forgot about wearing a shirt with sleeves. He spent 2 hours welding while wearing a tank top. I have never seen a sunburn so bad. The funny thing was, he knew exactly why he was an idiot, it just slipped his mind.

I wore a welding mask, gloves...with shorts and a T-shirt. Spent about 10-minutes welding. One of the worst UV burns ever. It was my first time arc-welding. I had no idea.
