Assessing MMA Welding Process Stability Using Machine Vision-Based Arc Features Tracking System
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,

Effect of main arc voltage on arc behavior and droplet transfer in tri-arc twin wire welding
Increasing the weld deposition rate invariably increases the welding heat input in monofilament arc welding or high efficiency twin wire arc welding and hence cannot be easily optimized to satisfy the needs of special applications requiring high weld ...
