| Research Abstract |
The aim of the present study was understanding and precise prediction of arc welding process, and then its dynamic behavior was analyzed from numerical simulations and experimental observations using an imaging spectroscopy. The present study revealed contents of metal vapor in the arc plasma and their concentrations, dynamic changes of plasma temperature and heat intensity into the base metal, and also time dependence of weld pool formation during the arc welding process
