The emergence of 3D characterization tools has permitted significant advancement in the field of materials characterization. As an emerging solid-state joining process, plasma arc welding (PAW) feature multiple microstructural characteristics such as flow patterns, flash, and pores that can benefit from 3D analyses. In this study, ceramics based on SiC/ZrB2/ZrC compositions were welded. Varying welding parameters such as arc power and plasma flow resulted in changes in weld pool shape and size. The porosity distribution, as well as phase percentage variations were analyzed using Robo-Met.3D, an automated system for 3D materials characterization. The optical microscopy data was analyzed using a software packages capable of performing each stage of post-acquisition processing and analysis. The resulting visualizations and analyses provide insights into the plasma arc ceramic joining process.
