Investigation Of Corrosion In WAAM Manufactured Materials

Investigation of Corrosion in WAAM Manufactured Materials
Available for download

Among the many additive manufacturing processes, Wire Arc Additive Manufacturing (WAAM) has recently been drawing interest due to its great and attractive prospect for fabrication of large parts, the possibility to process a vast range of materials in form of welding wires, and the addition of further details to semi-finished components [1]. However, most of the research have currently focused on optimization of the WAAM process parameters and analysis of the resulting thermal and residual stresses [2]. Unlike conventional manufacturing processes, WAAM process and post-processing treatments result in unique microstructures and material surfaces that alter the corrosion performance of the materials but are not fully studied or understood yet.

To develop the commercial applicability of Wire-Arc Additive Manufacturing (WAAM), there is a crucial need to understand the corrosion behaviour of the fabricated materials for industry acceptance. It is wellknown that WAAM process has a complex thermal process, resulting in unique microstructures and material surfaces. The current studies on corrosion resistance in the WAAM process are focused on Stainless Steels, Steels and Nickel-based alloys due to the potential industrial applications. Hence, a comprehensive review of the resulting microstructural evolution and corrosion resistance of the WAAM manufactured Stainless Steels, Steels and Nickel-based alloys has been presented.

AM brings significant benefits in better performance, inventory management, and lifecycle cost reduction to the Oil & Gas industry. Both manufacturers and users are working towards AM qualification and standardization in order to realize and sustain these benefits. Starting at the product level, the goal is to ensure the product is sound in its form, fit, and function, and free from macroscopic (surface, sub-surface, internal) anomalies deleterious to its performance. Product qualification is supported by a foundational metallurgical or AM material qualification.1

The overall goal was to determine if a set of additive manufacturing (AM) parts could comply with the testing requirements of wrought or welded materials for sour service as outlined in NACE MR0175 / ISO 15156-3:2015. Recommendations for a qualification pathway for AM parts in sour service are included.

Seawater injection is commonly utilized for offshore wells to maintain or increase oil production; however, treatment for seawater before injection is always necessary to reduce or remove bacteria, dissolved oxygen, sulfate, and other impurities. Seawater typically has >2000 mg/L sulfate. Without proper sulfate removal, such high levels of sulfate can cause not only barium sulfate, strontium sulfate, and calcium sulfate scales, but also reservoir souring and H2S corrosion in the presence of sulfate reducing bacteria (SRB). Therefore, sulfate removal from seawater is critical before seawater injection into reservoir.
