The objective of the research was to evaluate the potential of refractory chromites from Victoria I deposit (in Camagüey, Cuba) as a source of chromium for producing electrodes to recharge parts by manual electric arc welding. A mixture of rutile, graphite, refractory chromite, sodium silicate and AISI 1009 steel rods was used as raw material. The experimental electrodes were obtained by pressing the coating from a dosed mixture with the previous components. The mass balance predicts the weld bead can be alloyed with carbon and chromium by introducing refractory chromite and graphite in the rutile coating. The experimental results corroborated that the welding process allowed obtaining 2.3% carbon and 2.89% chromium in the metal deposited by the experimental electrodes. Results show that refractory chromites from Camagüey constitute a potential source of chromium for manufacturing rutile-coated electrodes for recharging parts by manual electric arc welding.
