Friction welding is the process of joining two metals together by spinning them rapidly until they heat up enough to meld together. Anni, Lauri, and his dad Timo from the Beyond the Press channel show how rigged up an old manual lathe to join two hammers together by rapidly spinning one while the other was stationary.
If you’ve ever walked through an outdoor sculpture garden, you’ve probably seen sculptures that move when the wind blows. Artist Anthony Howe is known for creating kinetic sculptures like these. In this video, he provides a glimpse into the painstaking process that’s involved in making these dynamic and precise works of art.
As we’ve seen before, it’s possible to make a weapon out of melted washers. But Hassan Abu-Izmero was challenged by a friend to build a viking axe by welding the washers together, rather than melting them down and forging them. The resulting axe looks super cool, and actually works thanks to its razor-sharp cutting edge.
While humans are still very much a part of assembling vehicles, robots are often used for the heavy lifting and dangerous tasks like painting and welding. Watch in awe as an army of 45 KUKA robots work in harmony at MAGNA Presstec to create frames for the Mercedes-Benz G-Class SUV.
Magnets are extremely useful for welding steel, as they can be used to hold pieces securely together without clamps. Strong Hand Tools magnets are unique thanks to their double-jointed design, which allows them to hold round, flat, or square metal parts at any angle, and in a snap.
Looking for a project to put basic welding skills to use? Check out this DIY idea from Ollari’s – a lamp with a shade made by welding a bunch of steel nuts around a curved form, and a base made out of the same. It’s a cool enough design that we’ll forgive his spelling of “baking soda.”
While much welding is done by adding molten hot metals with a torch or electrical current, friction welding creates strong joints by rubbing metal together at a high speed. Here, two blocks of titanium are merged into one. If you thought that was cool, check this out.
