Plasma transferred arc welding (PTAW) hardfacing of components is a vital and complex science. Numerous military, industrial, and commercial products (e.g., pumps, augers, valves, etc.) depend on the hardfacing process to provide a wear-resistant surface so components can achieve optimum performance efficiency and service life. The science of hardfacing is complex because an intimate relationship exists between respective welding processes, component design, and the hardfacing alloy/base metal metallurgy. Welding p..
