Apply the power of ultrasonics to welding, joining and more. Ultrasonic technology offers a high-power tool for a broad range of manufacturing applications. For more than three decades, EWI has been a pioneer in developing ultrasonic technology for joining solutions. Our applied R&D program helps manufacturers harness the unique qualities of ultrasonics to successfully join […]
Read MoreJerry Gould, EWI Technical Fellow for Resistance and Solid-state Welding, will be a featured speaker this month at the 6th Annual Global Automotive Lightweight Materials (GALM) Summit in Detroit. His presentation, Joining As An Enabling Technology For the Manufacture of New Generation Lightweight Automotive Structures, will cover the following: Technical challenges in welding of new […]
Read MoreWhy Polypropylene Cannot Be Welded with ABS In order for two materials to weld, there are three main requirements. The materials must be chemically compatible (i.e. the polymer chains must be able to form secondary bonds). Some plastics are compatible this way, however it is mostly different types of amorphous plastics that are compatible with […]
Read MoreManufacturing 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 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 […]
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, […]
