Today’s FSW “Meet the Team” features Tim Stotler. Tim has been at EWI for almost as long as there’s BEEN an EWI – 26 years. Tim “grew up” on resistance and solid-state welding processes and is currently the Technology Leader for friction processes at EWI. Tim has literally been involved with the Friction Stir Welding […]
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 MoreDesign engineers are increasingly faced with the need to join dissimilar materials as they are seeking creative new structures or parts with tailor-engineered properties. Sometimes a part needs high-temperature resistance in one area, good corrosion resistance in another. Structures may need toughness or wear resistance in one area combined with high strength in another location. […]
Read MoreFriction has been used to weld parts for both new make and for repair for many decades. The friction welding family of processes encompasses many different variants, including rotary friction welding (inertia, direct-drive, and radial), linear friction welding, and more recently, friction stir welding (FSW). In each case, friction heats the material to a plastic […]

Please don’t hesitate to contact Nick if you have any questions or interests related to EWI or Arc Welding. You can reach him at 614.688.5000 or [email protected]. Technical Expertise Nick Kapustka is […]
Read MoreLightweighting is a process of replacing a material with another to reduce weight while maintaining performance. Automotive reduces weight to improve fuel efficiency primarily since the payload itself is fairly constant. Aerospace uses lightweigting to increase payload and range. In that respect, the advantage of lightweighting for heavy manufacturing is closer to that for the […]
Read MoreThis installment of “Meet the Team” features Randy Dull. Contrary to his name, he is a quite personable fellow that is very knowledgeable with all things arc welding. Please don’t hesitate to contact Randy if you have any questions or interests related to EWI or Arc Welding. You can reach him at 614.688.5095 or [email protected]. […]
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 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, […]
