Don’t even ask how much this fuel tank will cost to fill. The giant cylinder is just one of the two tanks that will hold the fuel used to power NASA’s new Space Launch System when it blasts off to take missions to Mars and deep space.
In recent decades, material scientists have made ever-stronger metals—but the techniques used to weld them often ruin their properties. Now, a team has developed a way to weld together these previously un-weldable materials.
Here’s a really lovely process of metal working from Artismia: he melts down these basic metal rods into this metal glob and then stylizes and polishes and shaves down the glob into a beautifully designed door knocker. It’s surprisingly fun to see the entire transformation, like making art from nothing.
Friction welding spins so fast and burns so hot that it looks like the excess orange metal is something that's not meant for this world. The metal pipes forge together so colorfully (and almost unnaturally) that I never get bored of watching the process.
A few weeks ago, a tiny gallery in London was transformed into a scene straight out of the 19th century. Amid piles of sand, a worker donned a silver apron and safety helmet and poured molten hot steel down a track to create long slabs of metal. The man in the apron was Raphael Hefti—not an industrial worker, but an…
By now we all know that graphene has tons of potential applications, from virtually no-light camera sensors, to terabit upload speeds, to all your wildest dreams. Now, researchers have figured out how to chemically spot-weld graphene, wiring tiny graphene structures to real electronics with one-atom wires.
GE has a new 20kW hybrid laser arc welding (HLAW) system that's a lot more advanced than the welding methods we have now. Comparatively speaking, the new GE laser wields enough power to weld one-inch thick steel in a single pass. Current welding technologies need up to a half dozen passes.
