Droplet transfer in arcing-wire GTAW
Journal of Manufacturing Processes, 2016Abstract In arcing-wire GTAW process, the wire melting speed and weld penetration are decoupled. To well study the arcing-wire GTAW, especially the droplet transfer mode, the forces imposed on the droplet are analyzed firstly and compared with those in conventional GMAW. Then the experiments have been carefully designed and conducted.

Effect of GTAW on the Mechanical Properties of Mild Steel
Journal of Advanced Mechanical Engineering Applications, 2022 Tungsten metal arc welding (GTAW) is a highly popular welding technique in manufacturing. The welding factors such as welding current, voltage, speed, and gas flow rate play a significant role in determining the welding quality. This study discusses the effect of GTAW factors on the mechanical properties of commercial steel welding. Base

Journal of Materials Processing Technology, 2020
Abstract A notable advantage of the GTAW process with the use of a hot wire is the higher deposition rate, which can be twice as high as that achieved with a cold wire for the same welding current. In the conventional procedure, the wire is heated through the passage of current to create heat by the Joule Effect.

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

Development of Activated Flux for Deep Penetration in GTAW
Materials Today: Proceedings, 2019Abstract Gas metal tungsten (TIG) welding is one of the best suited fabrication methods in industries due to lower capital cost, contamination free and sound quality of weld joints. However, there are few drawbacks like the limited penetration capacity and limited productivity in TIG welding.

Improvement of Arc Properties in GTAW of Aluminium Alloys
Materials Science Forum, 2019Gas tungsten arc welding (GTAW) is a widely used method of joining aluminium and its alloys. Despite the fact that a lot of research has been done in this area for several decades, there are many unresolved issues on the welding process control. Optimization of square wave alternating current profiles is one of them.
