Process stability for GTAW-based additive manufacturing
Rapid Prototyping Journal, 2019Abstract Purpose Traditional gas tungsten arc welding (GTAW) and GTAW-based wire and arc additive manufacturing (WAAM) are notably different. These differences are crucial to the process stability and surface quality in GTAW WAAM. This paper addresses special characteristics and the process control method of GTAW WAAM.

Keyhole thermal behavior in GTAW welding process
International Journal of Thermal Sciences, 2017Abstract GTAW was found to be able to conduct keyhole mode welding when the applied welding current is high enough with a special-modified torch. GTAW uses free-burning arc as the heat source, the keyhole thermal behavior should differ to that in plasma arc welding. In this paper, to understand the keyhole process in the novel keyhole welding process,

Model Predictive Control of GTAW Weld Pool Penetration
IEEE Robotics and Automation Letters, 2019Weld pool penetration is a major indicator of weld integrity but it is not directly measurable. The key to solving this issue is to find or create observable phenomena that can be used to derive the penetration. An innovative method has recently been proposed/developed to derive the penetration from the reflection of projected laser from an oscillating

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.
