Research Paper


The development of new welding consumables requires several samples and experiments that must be performed to achieve the required mechanical properties. In the development of a metal-cored wire with a target tensile strength of 1150 MPa and acceptable impact toughness, thermodynamic and kinetic calculations via MatCalc were used to reduce the experimental work and the resources required. Micro-alloying elements were employed to obtain high strength as an alternative approach to conventional solid solution hardening. Investigations of the microstructure were performed via atom probing to understand the effects of micro-alloying elements. In particular, the influences of different elements on the precipitation behaviour in the weld metal were evaluated. The calculated mechanical properties are in accordance with the results obtained from experiments and can be explained by microstructural investigations. The approach is exemplified through vanadium and clarifies an efficient development route.
