Influence of the welding current on the consumption parameters of tubular electrodes from hardfacing of pieces in sugar industry

Abstract

It is carried out the determination of consumption parameter of coated tubular electrodes for hardfacing of pieces in sugar industry. Two versions of coated tubular electrodes (ferroalloy particle size in the soul ≤0,1 mm and in the range of 0,1- 0,25 mm) are evalueted. This study is made in comparative way, using the DIN E60-10 Z commercial coated electrode, which has same diameter (4mm) and same application (hardfacing, widely applied in sugar industry) as this studied. Starting from the results, the best operational range for this electrode is established, in that referred to welding current, looking for the biggest efficiency in the application.
