      abstract     = {In the fusion-based welding processes, filler materials are
                      commonly used to adjust and improve the composition of the
                      fusion zone with the aim of optimizing both microstructure
                      and mechanical properties. However, in the field of welding
                      high entropy alloys, the influence of different filler
                      materials on the microstructure and mechanical response is
                      still scarce, owing to the yet incipient usage of welding
                      technologies for these novel, advanced engineering alloys.
                      To bridge this knowledge gap, Inconel 625 filler wire was
                      used during gas metal arc welding of the well-known
                      CoCrFeMnNi high entropy alloy. To systematically analyze the
                      microstructure evolution and mechanical properties of the
                      welded joints, multiscale characterization techniques were
                      employed. It is shown that the different regions of the
                      welded joint possess distinct microstructural features due
                      to the weld thermal cycle, which is further compounded in
                      the fusion zone by the introduction of the filler material.
                      The use of Inconel 625 filler promotes a solid solution
                      strengthening effect in the fusion zone and became the main
                      contributor to the yield strength of this region (302 MPa
                      (via solid solution strengthening) vs 478 MPa (yield stress
                      from tensile experiments). Since Hall-Petch strengthening is
                      predominant in both base material and heat affected zone,
                      but not on the fusion zone due to the large grain structure
                      that developed, the addition of Inconel 625 filler
                      demonstrates to be a feasible approach to increase the
                      typically low fusion zone strength. By coupling
                      microstructural characterization with mechanical property
                      analysis, aided by the calculation of the strengthening
                      mechanisms, we unveil processing, microstructure, property
                      relationships, providing a broader basis for the widespread
                      application of gas metal arc welding for high entropy
                      alloys.},
