Additive manufacturing has gone from the future of manufacturing industry to one of the widely investigated domain in the manufacturing industry.
One of the key characteristics of additive manufacturing is high initial cost of manufacturing and need for special equipment. With Wire-Arc additive manufacturing, it is industrially feasible and economical to adopt the AM method for producing large components of engineering materials.
This work will adapt the understanding of steel weld metal microstructures in multi-pass butt welds to support the development of new welding consumable compositions which are optimised for additive manufacturing.
The alloying elements present in the consumable will have an optimised composition such that a desired microstructure along with material properties, is obtained at the end of the printing process.
