Applying Lessons from Welding to Large Scale Metal Additive Manufacturing

Picture for Applying Lessons from Welding to Large Scale Metal Additive Manufacturing
Available for download

Direct energy deposition processes that utilize wire feedstock have been deployed to deposit and fabricate near net shape functional metal parts at high deposition rates. Is this just multi-pass welding or is there more to it? Should the material requirements for additive be the same as those defined for welding? Is weld quality the same as part quality? A large metal additive part fabricated using a robotic wire arc additive system will be used to demonstrate the similarities and identify critical differences between essential variables for welding and additive manufacturing. The opportunities for both welding and additive manufacturing to learn and leverage one another to develop unique and novel materials, process controls and further fundamental understanding of metal deposition processes will be outlined.

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.

Alloy 718 is a common oilfield material for permanent and service equipment in need of high-mechanical ratings and resistance to corrosion especially environmentally-assisted cracking in sour gas wells. In past decade Alloy 718 production from traditional and newer mills has greatly increased in response to global demands; independently yet driven by similar market growth additive manufacturing (AM) has expanded beyond rapid prototyping to become an industrial production process namely in the aerospace. Today 718 bar stocks as per API6CRA are produced by over a dozen mills worldwide;similarly 718 powder products are increasingly offered by both traditional and newer mills with intents to servea multitude ofAM technologies. Due to the rise of new economic forces in the O&G there are today needs for evaluating (ultimately qualifying) newer 718 producing mills as well as 718 powders in combination with various AM technologies. Due to concerns overraw-material properties a study was conducted to analyze 718 materials from these various origins utilizing (1) mill cert big-data analyses (2) third-party recertified mechanical test data (3) a multitude of sour service test results outside the traditional NACE MR0175/ISO15156 operational service limits among others. The later raw-material test implemented in the early 2010s for screening and qualification purposes aims at quantitatively comparing 718 production heats of various origins and with additive manufacturing also generating interests since the early 2010sthe same tests have also beenextended to determine how layer-by-layer deposited materials compare to bar stock materials.
