If Rosie the Riveter had entry to a brand new riveting expertise, the character of WWII fame may have labored sooner and made lighter merchandise. As we speak, a newly patented riveting method developed by Pacific Northwest Nationwide Laboratory (PNNL) makes light-weight magnesium simpler to kind and reduces the time wanted to affix every rivet.
Magnesium is likely one of the lightest metals—making it ultimate for higher gas financial system in automobiles. Nevertheless it trails behind aluminum and metal in industrial use as a result of it is generally brittle and troublesome to form into structural elements. The brand new friction-based riveting expertise, referred to as Rotating Hammer Riveting (RHR), avoids the necessity to pre-heat the metallic to kind the rivet and improves the fastening joint. It additionally works on aluminum rivets, that are utilized in airplane development. The processing technique can be considerably sooner, which may save money and time in airplane and car development.
