Periodically, EWI Associates write to share their experiences on the job. Miranda Marcus, Applications Engineer in our ultrasonics group and technical lead for plastic and composite joining, has published several popular articles about her life as a engineer in the world of applied R&D. Her latest essay, recently published on the question-and-answer blog site Quora, […]
Read MoreEWI will again host its five-day Fundamentals of Welding Engineering course at its Columbus, OH, headquarters, November 10-14, 2014. Taught by top-notch EWI engineers, this class provides engineers and technicians with an overview of the various aspects of welding technology including welding processes, welding metallurgy and weldability, welding design and testing (including mechanical testing and NDT), and qualifications and procedure review. […]
Read MoreThe Crazy Brilliance of Radio Frequency Welding When it comes to welding plastics, three contributing factors matter: heat, force, and duration. While there are multiple ways of controlling and applying each of these, the heating method defines the welding process: Welding Process Heating Method Vibration Surface Friction (linear) Spin Surface Friction (rotational) Hot Plate Conductive […]
Read MoreThis week the “Meet the Team” series introduces George Ritter of the EWI Materials group. George specializes in the areas of adhesives and plastics. George has spent over 30 years in industrial research environments, with much of that time spent on structural adhesives bonding applications. Please feel free to contact George if you have any […]
Read MoreIn the most recent EWI Insights, there is an article highlighting a recent Friction Stir Welding (FSW) study with Polypropylene with nanocaly filler. This welding study showed that superior weld joints could be obtained in thick section thermoplastic composites. The weld strengths obtained for 6 wt% nanocomposite were significantly higher than those found during other […]
Read MoreWhile ultrasonic welding is one of the most popular plastic welding processes, it is also the most sensitive.There are many interdependent factors that make this welding process a nightmare in many manufacturing environments including complex joint designs, material considerations, tooling, and environmental factors. Ultrasonic welding can be very successful if its limitations and process requirements […]
Read MorePlastic is constantly incorporated into new applications. As one of the go-to plastic welding specialists, I have the opportunity to develop assembly processes for several unique and challenging applications. I have had experiences welding components ranging from several meters to a few millimeters in length. It is truly exciting to work on such a variety […]
