Plasma Transferred Arc (PTA) hardfacing is a versatile method of depositing high-quality metallurgically fused deposits on low cost surfaces. Soft alloys, medium and high hardness materials, and carbide composites can be deposited on a variety of substrates to achieve diverse properties such as mechanical strength, wear and corrosion resistance, and creep. PTA hardfacing has significant advantages over traditional welding processes such as oxyfuel (OFW) and gas tungsten arc welding (GTAW).
