Abstract: High entropy alloys have emerged as novel engineering alloys with remarkable mechanical properties in a widerange of temperatures. Among the several high entropy alloys that were already described, the equiatomicCrMnFeCoNi alloy is the most studied one. In this work, gas tungsten arc welding of as-rolled CrMnFeCoNihigh entropy alloy sheets was performed. The microstructural characterization encompassed the use of electronmicroscopy, including electron backscattered diffraction, synchrotron X-ray diffraction analysis, microhardnesstesting and mechanical evaluation. A comprehensive description of themicrostructural evolution, including textureand microstrain determination, of the joint is presented and discussed. Upon mechanical testing, the jointssystematically failed in the fusion zone due. The large grain size and low hardness of this region justifies the failurelocation. The joints' mechanical behaviour is correlated with the material microstructure.
