Study of the efficiency, performance of welding metal and deposition coefficient of the Esab brand e6011 sticked electrode

Abstract

This work aimed to determine the efficiency, performance and deposition coefficient of the E-6011 electrodes for the SMAW process, under the UNE-EN ISO 2401 standard of the ESAB brand. The study was carried out in the city of Santo Domingo using the quantitative approach and a total of 2 test tubes for each of the ESAB E6011 electrodes, with their respective diameters and amperages. This comparative study evaluated the performance of ESAB E6011 electrodes of two diameters 1/8 and 5/32 inches in the SMAW welding process. The results indicate that both diameters exhibit similar nominal and effective performance, with minimal material losses during welding. However, the 5/32-inch electrode demonstrated slightly better overall performance, characterized by higher metal transfer efficiency to the weld bead and higher deposition performance. This higher efficiency is supported by a higher deposition coefficient on the 5/32- inch electrode, suggesting better current utilization and welding time. It is concluded that the ESAB brand E6011 coated electrode is a reliable and efficient option for welding applications that require high quality and performance, given its mechanical properties, arc stability and deposition coefficient.
