Excellent joint efficiency in GTAW hot wire narrow gap applications

摘要

Where weld joints must exhibit strength, integrity and corrosion resistance, such as thick walled components for super critical power plants or nuclear power plants, the application of hot-wire Gas Tungsten Arc Welding (GTAW) - specifically GTAW narrow gap welding (GTAW-NG) - is finding increasing use. GTAW-NG is generally regarded as a low deposition process and higher deposition processes often find wider use within the power generation industry. However, GTAW hot wire offers superior weld properties and excellent joint efficiency in narrow gap applications.
