Friction 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 […]

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 […]
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 MoreYou may remember we recently purchased a LECO GD-500A OES chemical analysis system to round out our weld testing capabilities (see my previous link – https://www.ewi.org/chemical-analysis-testing-time). Well it is finally here and we are officially running! The LECO GDS-500A is an OES (Optical Emission Spectrometry) chemical analysis system for elemental analysis of ferrous and non-ferrous […]
Read MoreThe EWI Materials and Lab Services teams are very excited to announce the acquisition of a Glow Discharge Spectrometer (GDS), bolstering our current chemical analysis capabilities. The GDS unit will allow EWI to perform bulk chemical analysis in-house, very quickly, and extremely accurately. Our GDS is currently calibrated for low alloy steels, stainless steels, nickel […]
Read MoreHybrid arc welding pairs two arc welding processes such as GTAW (Gas-Tungsten Arc Welding) and PAW (Plasma Arc Welding), or GMAW-P and PAW. Predominant advantages are high penetration up to 3/8-in (9 mm) with keyhole PAW and simultaneous filling of a small vee groove to weld ½-in or more in a SECB configuration for stainless […]
Read MoreUltrasonic Metal Welding is a unique process that has typically been limited to applications involving softer, high conductivity alloys. Skipping over the physics and metallurgy of the process; let’s just say that high-frequency vibrations are transferred to the work pieces via a set of ultrasonic tools to create a solid-state bond. For welding softer materials, […]
