Since 2006, Siemens Energy has demonstrated a continuing commitment to high-quality additive manufacturing through both Laser Powder Bed Fusion (LPBF) and Wire Arc Additive Manufacturing (WAAM) technologies. This discussion outlines Siemens Energy’s strategic approach to material development and part production for US Navy hardware utilizing WAAM technology. The project focuses on the use of ER70S filler material while adhering to ASME BPVC Section IX and US Navy specifications to ensure compliance with established WAAM standards. The proposal emphasizes a comprehensive delivery schedule and a strong focus on sustainability. A detailed Manufacturing Process Control Plan (MQCP) will guide the verification process, incorporating build strategy reports, mechanical property testing, and structured light scanning to fulfill quality assurance requirements. Siemens Energy prioritizes collaboration with all stakeholders in the value chain, facilitating testing, inspection, approvals, and acceptance processes. The partnership with Scot Forge FAST test center enhances testing capabilities, reinforcing the initiative’s commitment to effective material and part verification. This initiative represents a significant advancement in maintaining high standards of quality and compliance throughout the manufacturing process, ultimately supporting the US Navy’s operational readiness and sustainability goals.
Learning Objectives:
understand the differences between traditional Navy WAAM qualification process vs a "new method" aligned to the US Navy Tech Pub documentation.
Understand how WAAM has led to a reduction in lead time from PO to Part delivery
Understand how WAAM leads to an increase in quality over casting equivalent hardware.
