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.
