Press Release: AT&F Wisconsin Upgrades Facility

AT&F is pleased to announce recent upgrades to our Wisconsin facility, including a brand new plasma and oxy-fuel cutting table with a 5-axis beveling head, and improvements to a large capacity boring bar. In addition to the equipment upgrades, AT&F Wisconsin is pleased to announce the addition of a Certified Weld Inspector (CWI) to further enhance the welding quality and provide a valuable resource for proper procedures and training. These upgrades are part of AT&F’s continuous improvement initiative and bolster the Wisconsin facility’s capabilities for a competitive market.

From the Floor: Turbine Compressor Segments

AT&F manufactures for some of the most physically demanding markets. Inside a gas turbine engine, pressure and heat are built in a compressor to achieve maximum efficiency. The efficiency of the engine relies on the quality of the compressor; the more heat and pressure the compressor can handle, the more efficient the engine will be. AT&F has taken on the manufacture of segments of these compressors. Crimped, rolled, and burned from one piece of A36 carbon steel, the six-inch cylinder was then cut in half and blasted in our blasting room.

From the Floor - Rolled Tanker Cylinders

AT&F is big in the maritime industry. Shipbuilding is a process marked by compliance to established standards. So when AT&F was approached to form hawse pipes for the anchor system on heavy tanker ships, we put our expertise to work. The American Bureau of Shipping (ABS) standardizes the engineering of various grades of steel for shipbuilding, and the hawse pipes are no exception. The ABS-A carbon steel was cut, rolled, and tested to the specifications of the customer, but before shipping the parts out, an inspector from ABS visited our facility and spent two days verifying that every job had been done in accordance with ABS standards. After careful inspection the pieces were stamped, approved and sent off to the customer.

From the Floor - Heavy Cylinder Processing

When it comes to thick plate rolling, AT&F has you covered. If you've been following the blog, you'll remember a while ago when we posted photos of thick wall cylinder rolling. This is another one in the set of cylinders being prepared to ship to the customer to assemble a huge pressure vessel to produce low-calorie sweetener. This cylinder is unique because it is mostly comprised of standard carbon steel with a 1/4″ thick layer of 304 Stainless Steel cladding. Due to weight, the customer chose to ship the large cylinders one at a time and weld them in the field.

From the Floor - Heat Exchangers

Heat exchangers, like the ones pictured below, are used to heat or cool many different liquids. These components are used for numerous different applications in a wide range of industries. AT&F Advanced Metals has built many heat exchangers over the years out of specialty metals including tantalum, titanium, and various grades of stainless steel.

From the Floor - Bridge Girder Fabrication Part 2 - Welding

In our last post about short span bridge girders we showed some photos of the tub girders after we formed them in our long single ram press. In another process, we weld studs onto the bridge girders as shown in the photo below.

From the Floor – Thick Wall Cylinder Rolling

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.

From the Floor - Short Span Bridge Girders

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.
