Research Scale Plasma Transfer Arc Welding and Characterization

A PTA-AM platform is used for processing specialized metallic alloys and hard-facing materials, enabling controlled deposition and tailored surface performance. Research focuses on optimizing process parameters to refine bead geometry, reduce dilution, and improve mechanical properties. The workflow includes precision machining, edge preparation, and detailed metallographic sample preparation to support accurate evaluation. Material characterization covers hardness, modulus, yield and ultimate tensile strength, along with advanced methods such as XRM, EDS, SEM, and wear testing to analyze microstructure and functional performance.
