According to the 2017 Infrastructure Report Card published by the American Society of Civil Engineers, US bridges are continuing to deteriorate in condition with many elements approaching the end of their service life, receiving a “D+” grade. As a result, the Federal Highway Administration estimates that nearly 25.0% of the nation’s bridges require repair and replacement. Consequently, demand for industry services will increase as governments are left with no choice but to attempt to improve their bridges and elevated highways.
Recent advances in forging technology help to address the structurally deficient or functionally obsolete challenges faced within the US infrastructure industry. Our aim with this presentation would be to provide a better understanding of today’s forging technology as it relates to heavy movable structures and gearing.
Our objectives include:
Provide a metallurgical overview of forging. In critical load-bearing applications, the superior structural integrity of forgings makes them the preferred choice due to enhanced mechanical properties, impact strength and fatigue endurance limits… often boosting service life.
Examine options to upgrade castings, rolled and welded plate and machined bar stock to near net shape forgings in order to eliminate structural flaws and weldment problems for maximum strength components.
Discuss advantages/disadvantages of carburized gearing vs. through hardened gearing.
Discuss enhancements in finite element analysis for modeling of applications.
At the end of this lesson, the learner will be able to:
Identify the differences and best use-cases between five different metalworking alternatives (open die, closed die, ring rolling, casting and fabrication).
Describe how the Hybrid forge process can reduce manufacturing cost as compared to other metalworking techniques.
Correctly identify how grain flow affects fatigue problems and stress corrosion in metal parts.
Bridge owners, government agencies, designers, contractors, suppliers and other groups involved in movable bridges and heavy movable structures, as well as purchasers and R&D specialists. This includes both privately owned and publicly owned bridges.

Jeremy Copley has been with Scot Forge for 17 years; 13 of which he spent in the Forge Department working as a Blacksmith. Recently, he has transitioned to the Forging Development Team, where he pushes the envelope of forging design using 3D forging simulation software to prove out concepts. His experience both with engineering and manufacturing allows him to better communicate and collaborate with customers on their forging needs.
Kyle Rackers is a Senior Metallurgical Engineer at Scot Forge and a graduate of Missouri University Science & Technology (S&T). With more than 10 years of experience working with metals, he is a member of the Forging Industry Association (FIA) Technical Committee and sits on the FIERF Board of Trustees.
Patrick Nowak is a Senior Metallurgical Engineer with 17 years of experience and has been an active member of ASTM subcommittee A01.06 on Forgings since 2008. He is currently serving as the Secretary of this subcommittee, which has oversight for forging specification covering a wide variety of applications, including gears for infrastructure. He is also serving as a Producer Vice Chairman of ASTM Main Committee A01 on steel products. Patrick is also a member of the ABS technical specifications committee. He has extensive experience forging and heat treating carbon, alloy and stainless steels. (Guest Expert on webinar)
