Machine learning models for determination of weldbead shape parameters for gas metal arc welded T-joints -- A comparative study [PDF]
arXiv, 2022 The shape of a weld bead is critical in assessing the quality of the welded joint. In particular, this has a major impact in the accuracy of the results obtained from a numerical analysis. This study focuses on the statistical design techniques and the artificial neural networks, to predict the weld bead shape parameters of shielded Gas Metal Arc ...

Assessing MMA Welding Process Stability Using Machine Vision-Based Arc Features Tracking System
Sensors, 2020 Arc length is a crucial parameter of the manual metal arc (MMA) welding process, as it influences the arc voltage and the resulting welded joint. In the MMA method, the process’ stability is mainly controlled by the skills of a welder. According to that,

A Multi-Sensor Interface to Improve the Learning Experience in Arc Welding Training Tasks [PDF]
arXiv, 2021 This paper presents the development of a multi-sensor user interface to facilitate the instruction of arc welding tasks. Traditional methods to acquire hand-eye coordination skills are typically conducted through one-to-one instruction where trainees must wear protective helmets and conduct several tests.
