            "description": "Recent research of gas metal arc welding (GMAW) has proven that the sheath voltage dominates the total voltage fall in the current circuit and delivers most of the energy, which is finally transferred to the wire and the weld pool. This data set provides the results for droplet temperatures and the energy delivered to the wire anode in comparison with the sheath voltages. These quantities have been studied experimentally for a typical pulsed GMAW process in the one drop per pulse mode for mild steel under Ar with 2.5% CO2 with different peak currents from 350 to 650 A. A constant wire feed speed of 4 m/min as well as constant arc height are considered. The processes were studied with non-intrusive optical methods, i.e. without strong modification. The droplet energy was determined by high-speed two-color pyrometry and an analysis of the droplet surface temperature and geometry. In addition, the Joule heating in the wire anode was also estimated from surface temperature measurements. It was found that the averaged droplet energy is almost independent of the peak current and approximately 1/3 of the total electric energy. A voltage equivalent of the energy delivered to the wire anode from the plasma was deduced. Subtracting the work function of iron, the value of this voltage is around 3V. The detailed quantities can be found in this data set.\r\n",
