Adaptive Control of Aluminum Alloy GTAW Process

2010 International Conference on Electrical and Control Engineering, 2010
Visual sensing and adaptive control were combined in aluminum alloy pulse gas tungsten arc welding(GTAW) to control the penetration. The property of aluminum alloy GTAW was analyzed firstly. Stochastic system theory was used in the welding process, and the stochastic system model between the welding parameters and welding pool geometric parameters was ...

Cobalt-Base Superalloy Coating Using GTAW Process

Materials Science Forum, 2013
In harsh operational conditions, the low-alloy steels need to be protected from the environment. Thus, against corrosion and wear, an ordinary choice is metallic cladding. In this sense, the present study aimed to evaluate the properties of cobalt base superalloy coating deposited by gas tungsten welding process (GTAW) on steel SAE 4140.

Process stability for GTAW-based additive manufacturing

Rapid Prototyping Journal, 2019
Abstract 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, 2017
Abstract 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, 2019
Weld 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
