ABT Inc.

Our research and development of specialized welding equipment has allowed us to introduce an entirely new and unique fabrication process. This process virtually eliminates the distortion that is normally associated with the manufacture of waterwall panels. The Certi-Weld process includes: • Application of preheat and maintenance of heat throughout the welding process. • No bulging or distortion occurs during the welding process. • No extensive straightening is required after the panel is welded. • No stresses occur from the straightening process. Certi-Weld Overlay Panels At ABT, we have combined the weld overlay and the manufacture of waterwall panels into one continuous operation. Now, out customers can "sole source" overlay panels, improving the price and delivery of overlay projects. The benefits of Certi-Weld are as follows: • The tubes and membrane are clad and straightened prior to the assembly of the panel. • Eliminates the distortion from cladding an existing panel. • Eliminates the risk of "blow through" in the cladding process. • As in our unclad Certi-Weld panels, no excessive straightening is required which is usually a considerable problem with overlay panels.

SuperHeaters, Economizers, Re-Heaters, Waterwall Panels, Generating Tubes & Wall Openings ABT fabricates Boiler Replacement Products for utility, waste to energy, pulp & paper, O.E.M.'s and large & small industrial companies. Our capabilities include fabrication of carbon steel, stainless steel, Inconel®, and High alloy elements of all sizes & grades.

ABT produces custom designed die castings for industrial use according to ASME, ASTM and ISO standards. With advanced technology, rich experience, and mass production capability, we are able to offer cost-effective castings of the highest quality.Forging Process Forging is a manufacturing process in which metal is pressed, pounded or squeezed under great pressure into high strength parts by the application of compressive force through the use of a power hammer or machine press. Advantages Forging products have several advantages over other manufacturing processes. • Stronger and more ductile • Component repeatability • Consistent Quality • Long life Material Aluminum, Carbon, Alloy, Stainless Steels, Tool Steel, Titanium, Brass and Copper, etc. Equipment Crank Forging Press, Abrasive Forging Press, Hydraulic Forging press, Horizontal Forging Machine, etc. Maximum Mass 50, 000 lbs Dimensional Tolerance +-0.003"
