Additive Manufacturing in Power Plant Component Production and Repair

Over the past few decades, Additive Manufacturing (AM) has rapidly evolved, transforming industries around the world. In the power plant sector, technologies like Selective Laser Melting (SLM) and Wire-Arc Additive Manufacturing (WAAM) are making a significant impact on both the production and repair of critical components. This paper takes a closer look at these innovative techniques and their practical applications within the power industry, such as the creation and repair of turbine parts, boilers, and other essential equipment. The mechanisms of SLM and WAAM are explored, with a demonstration of how they enable the creation of complex parts with improved mechanical properties and faster production times compared to traditional methods. Along with this, the standards and regulations that shape the use of AM, such as AWS D۲۰.۱, API ۲۰۵, and the ۲۰۲۳ updates to ASME Sec. IX, are examined, with new guidelines for incorporating the Wire-Additive Manufacturing process into welding standards being included. The paper also emphasizes the benefits of AM in power plant maintenance, especially when it comes to cutting down on downtime and enhancing the performance of repaired components. Through a discussion of both the technological advancements and the regulatory landscape, this paper aims to offer a complete picture of how AM is becoming an increasingly essential tool in the power industry.
