Arc Characteristics of Ultrasonic-Magnetic Coaxial Hybrid GTAW. [PDF]
Materials (Basel), 2022 Ultrasonic-magnetic field coaxial hybrid GTAW(U-M-GTAW) is a new non-melting electrode welding method proposed by combining ultrasonic assisted GTAW(U-GTAW) and magnetic assisted GTAW(M-GTAW) on the regulation characteristics of the GTAW arc. U-M-GTAW introduces ultrasonic and magnetic field effects into GTAW to improve arc characteristics.

Comparison of SMAW and GTAW Welding Properties
Mechanics Exploration and Material InnovationLow carbon steel is a type of welding with good formability, machinability, hardenability, and weldability. It can be welded without preheating or postheating processes. Notch strength and sensitivity to weld cracking are the factors that influence the weldability of low carbon steel. SMAW and GTAW welding techniques were applied in this study.
