Chris Conrardy, EWI CTO, announced a pilot program to help small and medium-sized manufacturers address cybersecurity threats in an increasingly interconnected industry. This cybersecurity cooperative was introduced at “The Importance of Cybersecurity for Manufacturers.,” an event hosted by Manufacturer’s Edge, NoCO Manufacturing Partnership, and CAMA.
Read MoreIn his blog Who Let the Frogs Out?, my colleague Marc Purslow wrote about EWI’s innovative work to automate the repair of austenitic manganese steel (AMS) frogs; the special trackwork components used by railroads to allow track to converge, diverge, or cross. In this Phase I project sponsored by the Federal Railroad Administration (FRA), EWI […]
Read MoreNon-metallic inclusions are residual products from de-oxidation, de-sulfidation and other chemical reactions which take place in the steel making process. Since these inclusions serve as heterogeneous nucleation sites during the solidification of liquid steel, they are often found at grain boundaries. Modern high-strength low-alloy (HSLA) steels are produced using thermo-mechanically controlled processing (TMCP) to roll […]
Read MoreEWI is capable of performing orbital welding, a specialized welding process whereby the arc is rotated mechanically around a static workpiece such as a pipe in a continuous process. The technique was developed over 50 years ago, and with today’s modern technology is a sound, robust, and easy-to-use method of joining cylindrical components. These components can be […]
Read MoreI recently rode my bicycle across America and saw a whole bunch of craziness: A hurricane in Maine, hail storms in the Arizona desert, a haboob in the California sand dunes, and hundreds of giant frogs…giant steel frogs…more specifically, giant battered austenitic manganese-steel frogs! No, I didn’t lose my mind cycling for 43 days alone. […]
Read MoreFour months ago, I arrived fresh from the OSU Mechanical Engineering program to begin my first job as one of EWI’s design engineers. I am grateful to have initiated my career with such an innovative, technically advanced organization. In the short time since joining their design & advanced automation team, EWI has exposed me to […]
Read MoreBackground Self-shielded flux-cored arc welding (SS-FCAW) wires have been used on oil&gas pipeline since last century. Back to the beginning of SS-FCAW application on pipeline welding, the alloying strategy of line pipe steel was rather straight. It adopted a solid-solution strengthening mechanism to achieve the desired mechanical properties. Carbon, manganese, silicon are the most popular […]
Read MoreRefractory metals such as Ta, Nb, Mo, and W possess excellent corrosion resistance in many environments. They offer significant strength at high temperatures. While these elements are often alloyed with other non-refractory metals, their high-temperature strength and corrosion resistance are usually degraded by alloying. Though these metals are quite expensive, aggressive environments frequently require their […]

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 […]
