In the April issue of The Fabricator, Steve Massey, EWI’s Engineering Manager in the Arc Welding group, talks about technology advancements that can boost the performance in submerged arc welding (SAW). Specifically, he identifies techniques such as increased stick-out, twin-wire, and tandem welding. In the article, “3 Ways to Boost Submerged Arc Welding Performance,” Massey says that these three widely used techniques […]
Read MoreEWI hosted a welding merit badge clinic on Saturday 13 April for Boy Scouts in Columbus and the surrounding areas. The welding merit badge is one of the newest in scouting. It is the 128th current merit badge and was released on Feb. 24, 2012. The event was held at the EWI facility in Columbus […]
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 my June 28th blog post titled “Low-tech, High-impact!” I discussed work completed by EWI’s Steve Massey highlighting the benefits of mechanization of backgouging and welding as they relate to productivity. In this post I will review the basics of carbon arc gouging and discussing other benefits of mechanizing the process. Carbon arc gouging is a […]
Read MoreStrip cladding is a high-productivity option for surfacing applications which uses a wide, flat strip in place of a wire electrode. Much like submerged arc welding (SAW), the process takes place beneath a granular flux which melts and forms a slag to protect the molten puddle. There are two variations of strip cladding; submerged arc strip cladding […]
Read MoreIn the last 6 years, Brad Nagy, Steve Massey, and I have conducted a significant amount of research on tandem gas metal arc welding (T-GMAW) and have been consistently impressed by the versatility of the process. Tandem GMAW combines two independently-controlled GMAW torches into a single welding torch with a common gas-shielding nozzle. The two electrodes are in […]
Read MoreOne of the great things about working as a welding engineer is that since the discipline is so young, there is still a lot of room for innovation. Relatively speaking, many welding technologies are still in their infancy, so innovation is often par for the course. Since coming up with the “next greatest thing” is so […]
Read MoreOn Saturday March 31st a group of EWI staff competed in the pinewood derby race, which was put together by the Columbus Dispatch. Our competitors were Battelle’s armored car division, OSU-CAR and a real Cub Scout. The event was held by Battelle in their old building. Our team consisted of: Ed Herderick, Applications Engineer – […]
Read MoreToday marks the last day of Movember and our EWI Mo Bros gathered one last time for a group photo. During the month of November, Movember is responsible for the sprouting of moustaches on thousands of men’s faces, in the US, around the world and of course, at EWI. With their Mo’s, our engineers help […]
Read MoreMonica Day from NBC 4 Columbus was at EWI this week to kick off Movember with the EWI associates that are participating in Movember. Steve Massey (Arc Welding – 5.5 year goatee), Marc Purslow(Arc Welding – perpetual facial hair), and John Castorano(Shipping & Receiving – 35 year goatee) all sold raffle chances to cut off […]
