Abstract
A welding system using electromagnetic arc oscillation was developed for narrow groove welding. The arc and bead characteristics in narrow groove GMAW were shown using electromagnetic arc oscillation. Arc signal characteristics for automatic joint tracking were also investigated. The periodic change of welding current with electromagnetic arc oscillation was examined by experiments and numerical analysis and adapted to develop an automatic joint tracking system in narrow groove GMAW.
