Thermal efficiency on welding of AA6061-T6 alloy by modified indirect electric arc and current signals digitalization
Keywords:Thermal efficiency, AA6061-T6, Current, Data acquisition, HAZ
The results of the thermal efficiency on welding by modified indirect electric arc technique (MIEA)  of the 6061- T6 aluminum alloy are presented. These values are in a range of 90 to 94 %, which depend of the preheating employed. Thermal efficiency was obtained by means of a balance energy which considers the heat input, the amount of melted mass of the welding profiles, and welding parameters during the joining, especially of the arc current data acquisition. Also, some dimensionless parameters were employed in order to determine the approximation grade of the melted pool, the heat affected zone (HAZ), and their corresponding values with the experimental results.
