This is the third part in a series of posts about fabrication work that we do for the bridge industry including long forming and welding. In Part 1 we showed a photo of the formed bridge girder and in Part 2 we showed the same girder after it had studs welded onto it. The photo below shows the girder during the galvanization process which is performed to inhibit rust on the component.
When customers face big challenges they search for a supplier of big ideas and big solutions. AT&F recently rolled nearly 9” thick flat plates into cylinders for just such a customer. The pressure vessel shell segments are a combination of 1/4" thick 304 Stainless Steel plate and 8 ½” thick carbon steel backer plate fused by the explosion cladding process. AT&F used the largest plate roll in North America to roll the thick flat plate into cylinder segments in just a few hours at its headquarters in Cleveland, Ohio.
Since 2003, WIRE-Net has recognized manufacturing leaders who demonstrate WIRE-Net's mission through their work and accomplishments. Mission Builder Award Winners are selected for their role in strengthening manufacturing in Northeast Ohio and supporting WIRE-Net's goals – to create healthy communities and fuel economic growth.
Bridge girders, like the formed ones pictured below, will be used to replace tens of thousands of aging short span bridges throughout the country. These girders are a critical component of state-of-the-art bridge technology which drastically increases the speed that bridges can be built. See more about AT&F's bridge girder fabrication here.
Few companies have the capabilities to cold roll an 8" thick cylinder. This particular cylinder has been explosion cladded with a corrosion resistant metal.
NASCC: The Steel Conference is the place for engineers, fabricators, detailers and erectors to learn about structural steel design and construction, to interact with their peers and to see the latest products for steel buildings and bridges. The Steel Conference offers more than 100 technical sessions and is the premier educational event for structural engineers, fabricators, erectors and detailers. In addition to practical seminars on the latest design concepts and construction techniques, the Conference offers an extensive trade show (featuring products ranging from structural software to machinery for cutting steel beams) and plentiful networking opportunities. It's a once-a-year opportunity to learn the latest techniques, see the most innovative products and network with your peers and clients. One low registration fee gains you admittance to technical sessions, keynote address, the T.R. Higgins Lecture and the exhibition hall.
We are packaging some beautiful stainless steel rail parts for shipment today. These parts will end up being used as side sills for locomotives.
The process of rolling steel is more complicated than it might seem at first. Depending on the process used, different factors need to be considered. For example, cold rolling a part increases its brittleness which can cause it to break under the wrong conditions. When hot rolling, other factors need to be considered such as how to avoid or correct transformations in the material or thermal distortion.
We had the honor of having our customer on site to witness the inaugural use of our newest Cellulosic Ethonol unit. This biofuel unit was produced by AT&F Advanced Metals located in Orrville Ohio, specializing in corrosion resistant metals including titanium, zirconium, and hastelloy.
