| Abstract Scope |
The energy sector relies on scheduled shutdowns and maintenance to maintain operational integrity, but completing these processes efficiently within time and budget constraints remains a challenge. Unexpected component failures, without readily available replacements, can significantly extend downtime and escalate costs beyond those of a planned shutdown. Wire Arc Additive Manufacturing (WAAM) is being explored as a solution for on-demand fabrication. This presentation showcases a case study on the fabrication and qualification process of a 2” CL150 flange using WAAM. The flange was produced with ER70S-6 welding wire, classified under SFA 5.18, in accordance with ASME Section IX, QW-600 for Wire Additive Welding. Fabrication was performed using the Lincoln Electric Sculptprint RND WAAM machine and its proprietary Sculptprint modeling software. After printing, the flanges were milled to meet ASME B16.5 geometric specifications. They were designed to meet the mechanical requirements of SA 105 forged material specifications. This work demonstrates the qualification procedure for WAAM components and establishes the feasibility of WAAM as a manufacturing method for pressure components. |
