In general, recycled gypsum can be used. Of course, this depends on whether the recycled gypsum is a direct return from a process, such as from manufacturing gypsum boards, or whether the recycled gypsum includes parts from construction sites. Impurities, such as salts, silicones, retarders, accelerators, and others, thus affect how much of the recycled gypsum can be added to the production of gypsum wall blocks. Please share your contact information with us at gypsum@grenzebach.com, and we can exchange further information.

Thank you! 🤩

SpaceX uses it to build their rockets' bodies made of steel sheets. So it probably works with every metal.

@@gergelyjuhasz8654 Does this mean yes or no?

@@chrisallen2005 Yes but with caveats. If it's an exceptionally hard or high melting point material like tungsten, you'll probably break the rotating pin before you can weld, but materials like this are hard to weld by conventional means already anyways. For somewhat hard materials like a lot of steels, you may need to replace the pin fairly often which could be expensive but if your weld properties are improved enough vs. the conventional techniques then it may be worth it

@erichmielke672 no. though tungsten carbide is not typically joined by FSW processes, it can be. to directly respond to your question though, NO - in fact, FSW is employed on a massive range of material, from aluminium to superalloys like inconel, stainless steels, carbon steels, and even poly composites like UHMWP or nylon-poly.... the process is the same, you just have to change your rpm, feedrate, and probe type (or pin - the tool that is buried into the material, stirring the workpieces together). you might have a HSS probe for poly, and a coated, cemented carbide tool for use in high carbon steels or superalloys.

tungsten carbide is typically cemented@@thomasjones7380 ..employing FSW for carbide can be done theoretically, but the practical application is lol pretty impractical. inertia friction welding though, that's more common for tungsten. tungsten carbide/cemented tungsten carbide has an extremely high melting point, and as you increase the temp of carbide, it becomes increasingly brittle which makes it not the most appropriate candidate for FSW - especially when you consider that most probes are made of high carbon steel, or *drumroll* tungsten carbide.

Hello Mr. Torres, the application is realized with robots of type (or: named) KUKA KRC2. The customized gripper consists of vacuum grippers and counter holders. If you want more details, please contact us: www.inos-automation.de/en/contact/. Best regards from Stuttgart.

Friction stir welding is suitable for joining of non-ferrous metals with low melting temperature, like aluminum, copper or magnesium. FSW of steel is still in research, especially due to the low lifetime of the tools.
