Manufacturing electronic devices with materials only microns in thickness is no small task. Due to the challenges that come with the miniaturization of these devices and their components—the joining of dissimilar, often delicate materials, for example—it is crucial to develop joining processes that are reliable and repeatable. Each application calls for a different approach, and […]
Read MoreEWI is one of the few organizations in the world that can both develop and deploy new technologies to successfully help aerospace, automotive, consumer goods, defense, heavy industrial, oil & gas, advanced energy and rail companies bridge the gap between R&D and manufacturing implementation. Our manufacturing innovation solutions improve the latest manufacturing technologies ranging from […]
Read MoreWe receive many questions about the difference between soldering and brazing. They are very similar joining techniques, both involving the melting of a filler metal to join two or more components without melting the base material of the components. The American Welding Society (AWS) defines brazing as such a process which involves a filler metal […]
Read MoreWhen most people hear the word “welding” they think of the guy in the local garage with an arc welder and a mask, or the army of spot welding robots used to build a car body. You might be surprised to learn that there are many more welds in the sensors and motors in a […]
Read MoreBelow are highlights from Mark Norfolk‘s presentation on Ultrasonic Additive Manufacturing (UAM) a few days ago at the ASM Symposium at GE’s Global Research Center in NY. Mark is a senior project manager at EWI and the CEO of Fabrisonic, an EWI spinout. Ultrasonic additive manufacturing (UAM) is a novel new process that produces true metallurgical bonds with full density and […]
Read MoreEWI has a strong participation in the 2011 International Automotive Body Conference and Expo (IABC – www.bodycongress.org) which will be held at the Michigan State University (MSU) Management Education Center in Troy, MI on November 9-10, 2011. One of EWI’s senior engineers, Menachem Kimchi, Automotive Business Development Manager, will present two papers (co-authored by EWI’s […]
Read MoreWith Halloween coming up my wife and I have started to stock up on candy for the kids. Chocolate comes in all shapes and sizes, but have you ever wanted to design your own chocolate creation? Well new technology will let you do this. Recently additive manufacturing of chocolate has come to the market. ASTM […]
Read MoreFor many years, engineers have been fascinated with, and have come to rely on, the ability to create parts directly from CAD models for the purpose of visualizing design concepts or verify functionality. Stereolithography has served this need quite well for developing appearance models and prototypes. However, since these parts are generally fabricated from resins, […]
Read MoreMaterials that cannot be welded must be joined with mechanical fasteners, solder, braze, or adhesives. For extended service above 450oF, a solder or braze is required. At lower operating temperatures, adhesive bonding is used. Adhesives can bond many diverse material combinations and offer the best approach for joining dissimilar materials in corrosive environments. Fasteners, brazes, […]
