GOMEZ-PEREZ, Carlos René et al. Mc. Lean-Anderson design applied for recovered electrodes obtaining with carbon, chrome and titanium alloys. Ingeniería Mecánica [online]. 2013, vol.16, n.2, pp.132-143. ISSN 1815-5944.

In the present work the behavior of recovered electrodes for superficial filler with Shielded Metal Arc Welding (SMAW) process is study. For the experimental design a coating calculation procedure and a Mc. Lean- Anderson type experimental plan are used. On the experimental design a matrix, composed by Calcite (26,73 %), Ferrosilicio (19,02%), Ferromanganese (16,58%), Rutile (26,69%), Potassium Silicate (11,70 %), and a alloy, conformed by Graphite (2 ≤ X1 ≤ 10), Ferro Chromium (5 ≤ X2 ≤ 35 %), ferrotungsteno (5 ≤ X3 ≤ 10 %) and matrix (60 ≤ X4 ≤ 80 %) is conjugated. In the work some criteria on the selection of the levels limits to explore during the experimental plan are offer, starting from considerations on the materials employees, their ranges and the procedure of production of the electrodes.
