In this study, a model for the melting efficiency of Gas tungsten arc welding (GTAW) was developed and validated using experiments. It was found that the melting efficiency increases with current, speed, arc length and electrode tip angle. The melting efficiency is found to be stable with increase in electrode diameter. The results were compared with existing studies. © (2014) Trans Tech Publications, Switzerland.
